How A Polymer Is Important Class Of Reinforcement
1.INTRODUCTION
"A combination of two or more materials (reinforcement, resin, filler, etc),differing in form or composition on a macro scale". They usually consist of
high performance fibres as reinforcing phases and polymers or metals as matrices.
Generally two phases of composite they are matrix phase and reinforcement phase or dispersed phase. Matrix is the primary phase, having a
continuous character, and its usually more ductile and less hard phase, it hold the dispersed phase and shares a load with it another one is reinforced
phase is embedded in the matrix in a discontinuous form. This secondary phase is dispersed phase .it usually stronger then the matrix therefore it is
sometimes act reinforcement phase.
Composition of fibres reinforced composite the fibres are important class of reinforcement, as they satisfy the desired conditions and transfer strength to
the matrix constituent influencing and enhancing their properties as desire.
A polymer is defined as a long chain molecule containing one or more repeating units of atoms joined together by strong covalent bonds. A polymeric
material is a collection of a large number of polymer molecules of similar chemical structure . matrix rein which provide the continuous phase of the
composite is expected to serve. Provide a uniform distribution of the structural and environment load to the reinforcing fibre through a good adhesion
and a strong interface with the reinforcement. A absorb the impact of loads minimize

Mt1310 Unit 3 Lab Reports
The tensile testing was done on the three composite specimens (90В°, and two 45В°) were completed with a servo–hydraulic load frame with a wedge.
The one in the lab was the MTS 647 hydraulic wedge grip and an 810 material test system. The specimens had strain gages with a Wheatstone bridge
to collect data such as time, distance, load, axial strain, and transverse strain. From the strain gages, evidence can support how and when the specimen
material failed under the stress being applied to it. The test was run for three times on three different specimens. The first specimen that was tested in
the hydraulic load was the 0В°/90В° specimen, which is made of carbon and epoxy laminate composite. The 0В°/90В° specimen was tested first out of

The specimen ends were not thick or had moving wedge grips to keep it secure in the holders of the servo–hydraulic load frame. The movement of the
specimen in the machine causes some of the data to be an inaccuracy. Also, the transverse strain causes issues with the strain gages that are called
transverse sensitivity. The transverse sensitivity affects the accuracy of the data that is being collected for the transverse strain more than the
longitudinal strain. This is greatly seen in the percent difference in the strain values such as in one case the Longitudinal strain was .4% while the
transverse strain was 30%. Another issue with the strain gages was that if the strain gages weren't properly placed on the specimen the data accuracy

Epoxy Decision Making Research
Dispensing Machines:
The quickest and most straightforward strategy for grouting splits is with an epoxy resin distributor. The epoxy resin is blended in the blending
chamber as it is required; in this manner there is no worry about pot life and the risk of the epoxy resin setting up in the pot and in the lines.
A few sorts of hardware have been created with the end goal of pumping the best possible extents of epoxy resin sap and solidifying operator to a
blending spout or blending head at or close to the infusion port. This hardware is all restrictive in nature and along these lines it is impractical to give
any insights concerning its cosmetics.
An essential part of such gear is that it is difficult to know for certain what extents of ... Show more content on Helpwriting.net ...
The pumping of the blend into the primary port ought to proceed until the epoxy resin cement begins to leave the adjoining port. At that point the main
port is connected and the pumping operation to the following nearby port starts. In the wake of grouting into a port has been finished, a great technique
for stopping the filled port is by the utilization of decreased wooden dowels. Anything that can be constrained into the port to stop the stream of the
grout might be utilized (e.g., pencils, plugs, elastic tubing).Care must be taken to infuse the epoxy resin cement at such a rate, to the point that the
infusion weight does not surpass that weight which the surface seal can endure or which may harm the structure. On the off chance that port–to–port
go of epoxy resin glue is not demonstrated, grouting might be halted promptly and an examination ought to be led to figure out where the epoxy resin

Advantage And Disadvantages Of Cardanol
INTRODUCTION AND OBJECTIVES
Recently developed wide range of innovative monomers and prepolymers starting from cardanol, a renewable and low cost industrial grade oil
obtained by vacuum distillation of Cashew nut shell liquid (CNSL), extracted from the Cashew nuts. CNSL is a byproduct of the cashew industry. The
nut has a shell of about 3.2 mm thickness inside which is a soft honeycomb structure containing a dark reddish brown viscous liquid. It is called the
CNSL, which is the pericarp fluid of the cashew nut.
In the search for the cost effective modern materials, CNSL and its products have a significant role to play. Being renewable, it offers much advantage

Dynamic mechanical analysis showed that increasing fiber content provides an improvement in the rigidity of the composites. Cardanol modified
resol reinforced nanoclay composite was prepared and mechanical properties of the final composites were improved by doping a 6 wt% of nanoclay in
cardanol modified resol (CMR) into the epoxy matrix. The results show that a 15 wt% of CMR in epoxy is a most suitable ratio (Nguyen et al 2007).

Low Velocity Impact and Impact after Compression in Cork Based Composite material
ABSTRACT:
Experiments are carried out in the investigation to find out the role of cork as an ideal core material, which is used as a shield plate in the front of
land military vehicles to verify the energy absorption and damage tolerance. Composite materials are used in various industries these days due to its
high strength to weight ratio putting them into light weight applications. Vacuum Assisted Resin Infusion Method is chosen to manufacture the
laminate. Specimens are cut according to American Society for Testing and Materials Standards are used. Low velocity impact is carried out on the
specimens to observe the energy absorption capabilities of the specimens with two different testing variables i.e., energy level and amount of the
viscoelastic material. Afterwards, Compression after Impact test is carried out to study the Damage tolerance of the impacted specimen. The study of
all the results from the above tests shows us the energy absorption and damage tolerance with the presence of cork as a core material. Further studies
can be done in different energy levels, different viscoelastic materials and also different fibres and resins. INTRODUCTION:

Critical thrust force Analysis in Machining of GFRP with Coconut fillers using Jodrill
Abstract: Ever increasing pressure on industry to reduce costs and ecological need of the hour forms the basis of the present research endeavor.
Coconut coir is abundantly available in India as a bio–waste. Naturally available coconut fibers in their original form have been used as fillers in glass
fiber reinforced epoxy composites. Thrust force being an important parameter in drilling induced damage has been analyzed during drilling of the
fabricated composites at four different spindle speeds and three feed rates. Thrust force generally reduced with increase in spindle speed but increased
rapidly with feed. Stepped increase in thrust force was observed while analyzing thrust force signals due to geometry of Jodrill.
Keywords: Glass fiber reinforced epoxy laminates, Coconut fillers, Thrust Force
1.Introduction: It has been well established that drilling of FRP's lead to drilling induced damage thus reducing component's life and reliability.
Thrust force induced in drilling of FRPs is one of the major reasons for drilling induced damage [1]. Several studies have been made worldwide to
critically review the delamination induced in drilling of FRPs. These research efforts clearly indicate direct relationship of damage induced with thrust
force induced during drilling of FRPs [2–6]. Various mechanistic, mathematical and analytical models have been developed based on different
reasoning,

Scorching A Laminate Kitchen Counter
Laminate kitchen counters are easy to burn or scorch with a hot pan. To avoid damaging your kitchen counter top, you should always use a trivet.
However, if an accident does occur, you can try a few different methods to fix the burn on a laminate kitchen counter. Step 1: Create a paste with
baking soda and water. Use steel wool to work the paste into the burned area, and lift the stain. TIP: If a baking soda paste will not lift the stain on
the counter, try using Ajax or Comet and water to create a paste to attempt to lift the stain. Step 2: Use a sponge and water to remove the paste after
you have finished scrubbing. Dry the area with a rag. Step 3: Buff the kitchen with carnuaba wax to provide a small layer of protection and restore

Sometimes you won't be able to buff the burn spot away. The pan could have burned through the layer of laminate, making a serious mark that will not
be able to be fixed by removing the burn marks. Step 1: Fill the depression in the kitchen counter top left by the burn with two part epoxy and a metal
putty knife. Clean the knife immediately after use. Allow the epoxy to harden for the full time recommended by the manufacturer before continuing.
TIP: Only mix enough two part epoxy for the job, paying particular attention to the required proportions. Once mixed two part epoxy must be used
within 20 minutes: a chemical reaction, not outside air, is responsible for epoxy hardening. Step 2: Sand the area with a fine grit sandpaper to remove
any rough patches. Use a tack cloth or soft cloth to remove any dust that was a result of the sanding. Step 3: Apply laminate sealant to the surface of the
epoxy patch and the surrounding kitchen counter to blend the sealant. TIP: If your kitchen counter appears to be a bit worn, clean the rest of the
kitchen counter thoroughly, then apply laminate sealant to the entire surface. The sealant should restore the shine to the entire kitchen

The History Of Nanocomposites During World War II
The History of Nanocomposites Before the use of nanocomposites, humans have used natural composites to improve their welfare and way of life
throughout history. The Mesopotamians would use natural adhesive to glue wood pieces in different ways to make plywood. Archaeologists have
found multiple natural composites used by ancient civilizations, but one of the most prevalent was the use of straw. Utilizing straw allowed these
civilizations to increase the strength of their building bricks, thus making there shelters stronger. This is how natural composites were first used by
early humans. In the 1930s, numerous synthetic composite technological breakthroughs were born. "In 1935, Owens Corning launched the fiber
reinforce polymer (FRP) industry by introducing the first fiber glass. In 1936, unsaturated polyester resins were patented. Because of their curing
properties, they would become the dominant choice for resins in manufacturing today. In 1938, other higher performance resin systems like epoxies
also became available." (Cite) The creation of FRP was vital to the military during World War II due to its notably high to strength to weight ratio. Not
only was FRP used for electronic housings and other electronic components, but was also used to create the first fiberglass reinforced boat hull. The
war efforts spawned copious amounts of commercial products made with FRP. This is how synthetic and natural composites were revolutionized
during the 20th century. A

How Does Polychlorinated Biphenyls Affect The Environment
Polychlorinated Biphenyl or PCBs is a chlorine based organic compound with the formula of C12H10в€’xCLx . Polychlorinated biphenyls was used in
many different things such as coolants, lubricants for transformers, and other electrical equipment. The production of polychlorinated biphenyls is
stopped all together in the united states in the year of 1977 by the United States Environmental Protection Agency (EPA). The EPA did this due to the
buildup of polychlorinated biphenyls found in the environment. Since Polychlorinated biphenyls have built up in our environment this means that they
must have an affect on the environment. According to the EPA once polychlorinated biphenyls enter the environment it contaminates our drinking

Advantages And Disadvantages Of Composites In Oil Industry
COMPOSITES IN OIL AND GAS INDUSTRY
Composite materials are multiphase materials obtained through the artificial combination of different materials in order to attain properties that the
individual components by themselves cannot attain. They are not multiphase materials in which the different phases are formed naturally by reactions,
phase transformations, or other phenomena. An example is carbon fiber reinforced polymer. Composite materials should be distinguished from alloys,
which can comprise two more components but are formed naturally through processes such as casting. Composite materials can be tailored for various
properties by appropriately choosing their components, their proportions, their distributions, their morphologies, their degrees of crystallinity, their
crystallographic textures, as well as the structure and composition of the interface between components. Due to this strong tailor ability, composite
materials can be designed to satisfy the needs of ... Show more content on Helpwriting.net ...
Due to the use of them, mass of construction is reduced up to 80%. Composites are already greatly used for the production of pipe systems for fluid
transport, pressure vessels, drill pipes and their couplings, tanks for fluid storage, risers, pipes for "coiled drilling" installations, partitions on platforms
for the protection against fire etc. Basic advantages of the use of composite materials when compared to conventional material which is steel, are
reduction of mass of primary and secondary constructions, introduction of new technologies (for example installation of conducting infrastructures into
drill pipes), better physical and chemical characteristics (corrosion resistance, buckling strength), longer life time of the construction (for example
within 25 years carbon fibers lose 2–10% of initial strength), easy installation of the construction, higher safety at work, and minimum

The Advantages And Disadvantages Of Composites
The attraction of composites primarily stems from their ability to replace standard lightweight/high strength metals or wood with an even lightweight
/higher strength alternatively. Additionally, composites offer new design flexibilities, improved corrosion and wear resistance, low thermal
conductivity and increase fatigue life.
Advantages of using composite material are:
пЃ¶Composites can provide a specific modulus (ratio of material stiffness to density) that is three and half to five times greater than steel or aluminum.
пЃ¶The fatigue endurance limit is much higher than for steel or aluminum.
пЃ¶Composites can provide a specific tensile strength (ratio of material stiffness to density) that is approximately four to six times greater than steel or
aluminum.
пЃ¶Toughened composites can give impact energies significantly higher than aluminum alloys.
пЃ¶The potential for corrosion is significantly reduced.
пЃ¶Design flexibility is greater and can allow for physical property directionality in parts where desired.

The Weight Reduction Of The Drive Shaft
Abstract – Almost all automobiles (at least those which correspond to design with rear wheel drive and front engine installation) have transmission
shafts. The weight reduction of the drive shaft can have a certain role in the general weight reduction of the vehicle and is a highly desirable goal, if
it can be achieved without increase in cost and decrease in quality and reliability. It is possible to achieve design of composite drive shaft with less
weight to increase the first natural frequency of the shaft and to decrease the bending stresses using various stacking sequences. By doing the same,
maximize the torque transmission and torsional buckling capabilities are also maximized.
Key Words: Propeller shaft, Drive shaft, optimization,Composite material, Composite drive shaft design etc. INTRODUCTION
The advanced composite materials such as Graphite, Carbon, Kevlar and Glass with suitable resins are widely used because of their high specific
strength (strength / density) and high specific modulus (modulus / density). Advanced composite materials seem ideally suited for long, power driver
shaft (propeller shaft) applications. Their elastic properties can be tailored to increase the torque they can carry as well as the rotational speed at which
they operate. The drive shafts are used in automotive, aircraft and aerospace applications. The automotive industry is exploiting composite material

The Pros And Cons Of Froth Surf Board Spaces
At the center of each surfboard is some kind of froth, that is referred to in the business as a clear. Froth surf board spaces will decide numerous

Environmental Impact Of Plastics
In order to comprehend the environmental impact of plastic, it is important to understand the journey plastic takes from the time one throws it away,
to the time it ends up in the vast unknown. The first place most plastic travels to after being disposed of is a landfill. It can sit in these ever
expanding landfills for up to 1,000 years before it's able to decompose. During the time plastic lives there, rain water periodically floods through the
waste, getting absorbed by the plastic's water–soluble compounds. Some of these compounds are highly toxic, and when combined together, they
create a more harmful compound called leachate. This liquid is often times absorbed by the ground below, draining through and into other soil, into
groundwater, and into streams. As a consequence, the ecosystems and wildlife touched by leachate are polluted and poisoned. Other plastic that
doesn't end up in landfills after use is instead sent through our waterways into our ocean. A 2015 study by the journal Science reported that 8 million
tons of plastic ends up in our oceans each year. After arriving to the ocean, plastic spends its first few months floating around until it is carried into a
massive vortex of accumulated trash. There are five of these plastic–debris vortexes, called gyres, located around the world: The North Atlantic Gyre,
The South Atlantic Gyre, The Indian Ocean Gyre, The Great North Pacific Gyre, and The South Pacific Gyre. Plastic is trapped in the currents of these
gyres,

Advantages And Disadvantages Of Polyepoxide
Epoxy or polyepoxide is a cross linking thermosetting polymer that cures (polymerizes and cross–links) when mixed with a "hardener" or curing agent.
Most common epoxy resins are formed by the polymerization between epichlorohydrin and bisphenol–A. Dr. S.O. Greenlee of United States and Dr.
Pierre Castan of Switzerland were in the year 1936, first jointly synthesized bisphenol–A based epoxy resins.

The matrix used in this study was an epoxy polymer based on bisphenol–A resin (Araldite LY 556) and an aromatic hardener (Araldite HY 932).
Weight percentages ranging from 0.0225 to 0.15 wt% of the pristine CVD–grown [50] MWCNTs (diameter 5–10 nm, length a few microns) were first
dispersed in ethanol in an ultrasonic bath at room temperature for 1 h. The solution was then mixed with the resin and stirred for 1 h at 2000 rpm
at 80В°C. Ethanol was evaporated in a vacuum oven at 80В°C for 1 h, and the mixtures were stirred again for 1 h at 2000 rpm. After adding the
hardener, the mixtures were stirred at 2000 rpm for 15 min. The resulting epoxy nanocomposite was hardened in a vacuum oven at 140В°C for 8 h.
Composite sample containing 0.025% of CNTs in the epoxy resin show a remarkable improvement in the dispersion of CNTs in the epoxy resin due to
ultrasound exposure. At these lower filler fractions, neither the processing behaviour (viscosity) of the matrix nor the surface finish of the samples was

Composite Structure And Its Effect On Weight And Hardness...
Wonder composite materials, with a power and universal lightweight relative to weight and hardness properties fell over most of the store of metals and
alloys recently. Properties composite depends largely on the characteristics of its constituent materials, the distribution and the interaction between
them. In general, filler is the main load bearing Members, while the matrix keeps them in the desired location and orientation, as pregnancy transfer
means between the fillers and protects them from environmental damage. The composite characteristics may be part of the total volume of the
characteristics of components or the ingredients may interact cooperatively resulting in improved or better properties. Apart from the nature of the
constituent materials, engineering promote ( The size and size distribution) affects the properties of composite greatly. Composite structure is a
combination of two or more different constituents that can be physically distinguished, resulting in a final product that has better performance than
each individual constituent does. Composite materials consist of a matrix (polymer, metal or ceramic) and one or more reinforcing phases (fibers,
particles, flakes or fillers). The different constituents are combined judiciously to achieve a system with better structural or functional properties than
can be attained by any of the constituents alone. Composites are becoming an essential part of today's materials due to advantages such as low weight,

The fiber phase is usually made from materials that are usually stronger and have a higher modulus of elasticity than that of the matrix, but they are
often very brittle [2]. Therefore, the matrix phase is usually the source of the composites' ductility, whereas the fiber is the source of its strength.
Furthermore, composited have a wider range of properties than the other types of material; thus, they are used in more application. For instance, the
material used in fishing poles should have a high tensile and compressive strengths, and a high modulus of elasticity, as that they are subject to high
stresses, which they need to withstand without failing or going through much plastic deformation. Moreover, fishing poles have to be ductile and
flexible, as that they should have the ability to bend. Such properties cannot often be achieved by using a single type of material; however, those
properties can be found in different composites. According to Philips [3], fishing rods are commonly made of fibers glass or carbon embedded in a
matrix of epoxy or lignin.
Because of the unlimited number of matrix/ fiber combinations that can be used to form composites, and the great number of variables that can be
controlled in composite materials, composites can attain a wide range of mechanical properties. For instance, the mechanical properties depend on the
properties of both the matrix and the fiber phases; as that, the

Introduction: In order to conserve natural resources and economize energy, weight reduction has been the main focus of automobile manufacturers.
Weight reduction can be achieved primarily by the introduction of better material, design optimization and better manufacturing processes. The
achievement of weight reduction with adequate improvement of mechanical properties has made composite a very good replacement material for
conventional steel. A composite is composed of a high performance fibers such as carbon, Kevlar, graphite or glass in a matrix material that when
combined provides better properties compared with the individual materials by themselves. The composite materials are used in structural application
areas, such as in aircraft, space, automotive, for sporting goods, and marine engineering. The various type of glass fibers available are Carbon fiber,
C–glass, S–glass and E–glass. However, carbon epoxy material is better than other fibers but because of its high cost, it has limited applications.
Favorable relation between cost and properties of a material can be obtained with E–glass fiber/epoxy. The major step of composite in automotive
business is extension of use in to truly structural application such as primary body structure and to chassis and suspension system. These are the area
which has to sustain all major road load

Clutch Facing Clutch facing is the heart of clutch assembly which actually transmits power from engine to transmission or drive shaft. It is a friction
surface which binds face plate of fly wheel and pressure plate of clutch assembly. A major benefit to using a lining or facing is that it prevents
metal–to–metal contact within the clutch set, resulting in less wear and tear on the clutch components. Clutch facings tend to have mid–level
coefficients of friction, and are responsible for removing most of the clutch vibrations from the engine. They also aid in allowing engines to achieve
high speeds without damaging the components. Fig.1 Clutch Facing 3. Desirable Characteristics of Dry Clutch Facings Clutch friction linings are
subjected to severe rubbing so that generation of heat in relatively short periods takes place. Therefore, the lining material should have a combination of

Epoxy Lab Report
Various methods are utilized to modify epoxy resins to improve their toughness. Based on the structure–property relationships, the traditional chemistry
approaches have been: chemical modification of a given rigid epoxy backbone to a more flexible backbone structure; lowering the crosslink density by
increasing the molecular weight of the epoxy monomers and/or decreasing the functionality of the curing agents. The most common approaches are the
incorporation of dispersed toughener phase(s) in the cured epoxy matrix. The second phase includes rubbers, thermoplastics, block copolymers and
hard inclusions such as silica, glass beads, etc.

Another reason is the low glass transition temperatures of the rubbers that lower the maximum use temperature and the modulus of the epoxy resins.
The high performance engineering thermoplastics such as poly(ether sulfone)s, poly(ether ketone)s and poly(ether imide)s were used as toughener for
epoxy resins [34–36]. The major advantage of these thermoplastic modifiers is that their incorporation into epoxy resins does not result in reduction in
modulus and glass transition temperature. In comparison with rubber modified systems, the use of tough thermoplastic polymers offers better
improvement in fracture toughness for higher crosslink density epoxy systems. The advantages of thermoplastic modified epoxy systems lie in the fact
that the modulus and the Tg of the modified epoxy can be maintained, and the fracture toughness can be improved in direct proportion to the amount of
thermoplastic added. The use of reactive thermoplastic modifiers provides good adhesion between epoxy and thermoplastic phases. Several toughening
mechanisms that have been proposed for the thermoplastic modified epoxies [37]. These mechanisms are illustrated in the Figure

Cut And Chip Test Testing
Cut–and–Chip Test
Ohio Northern University
May, 2016 – July, 2016
Background: Cut–and–chip is a phenomena in tires that manifests itself primarily from prolonged off–road use. As the tires are used off–road, the tread
compound will be cut by rocks and eventually large pieces of the tread rubber are chipped off. Current tests involve manufacturing a series of test tires
and sending them to a test track in Texas. The tires are then run on a controlled gravel road. Each set of tires is run for 1000 miles, 500 each day for
two days. In each set of 500 miles, 100 miles are on flint rock and 400 miles are on the highway. The tires are then ranked visually by multiple engineers
to determine which rubber compounds demonstrate the best cut–and–chip resistance. Thus, current testing is expensive, time–intensive, and subjective.
Students at Ohio Northern University therefore built a tester that can use a lab test for tread rubber compounds. Cooper will be able to save time and
money by testing much fewer compounds with the road test. However, although this tester is a very successful design, the cut–and–chip lab test using
this tester is a brand new idea that has never been done by any engineers, as we know. Therefore, a summer intern project was created to investigate the
usage of the tester and the cut–and–chip lab test. It should be noted that the investigation is a proof of concept study that many trials have to be
performed to use the lab test for tread rubber compounds to
