An Experimental Investigation into the Grindability Aspects of Newly Develope...IDES Editor
Ceramics are getting widely used in many engineering applications. These ceramic materials need to be ground. Unfortunately, the ground ceramic components mostly contain surface/subsurface damages. To minimize the grinding induced damages selection of appropriate grinding process parameters is very important. Ceramic composite material (AlSiTi) has been selected in the present study to investigate its grindability. This research work deals with the analysis of the process parameters such as wheel speed, table feed and infeed as influential factors, on the force components, grinding specific energy and surface roughness values based
on Taguchi’s experimental design method. Scanning electron microscopy (SEM) has been used to analyze the subsurface damages. The result provides valuable insight into the grindability aspects of the composite ceramic (AlSiTi).

Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.

You could be a professional graphic designer and still make mistakes. There is always the possibility of human error. On the other hand if you’re not a designer, the chances of making some common graphic design mistakes are even higher. Because you don’t know what you don’t know. That’s where this blog comes in. To make your job easier and help you create better designs, we have put together a list of common graphic design mistakes that you need to avoid.

Transforming Brand Perception and Boosting Profitabilityaaryangarg12
In today's digital era, the dynamics of brand perception, consumer behavior, and profitability have been profoundly reshaped by the synergy of branding, social media, and website design. This research paper investigates the transformative power of these elements in influencing how individuals perceive brands and products and how this transformation can be harnessed to drive sales and profitability for businesses.
Through an exploration of brand psychology and consumer behavior, this study sheds light on the intricate ways in which effective branding strategies, strategic social media engagement, and user-centric website design contribute to altering consumers' perceptions. We delve into the principles that underlie successful brand transformations, examining how visual identity, messaging, and storytelling can captivate and resonate with target audiences.
Methodologically, this research employs a comprehensive approach, combining qualitative and quantitative analyses. Real-world case studies illustrate the impact of branding, social media campaigns, and website redesigns on consumer perception, sales figures, and profitability. We assess the various metrics, including brand awareness, customer engagement, conversion rates, and revenue growth, to measure the effectiveness of these strategies.
The results underscore the pivotal role of cohesive branding, social media influence, and website usability in shaping positive brand perceptions, influencing consumer decisions, and ultimately bolstering sales and profitability. This paper provides actionable insights and strategic recommendations for businesses seeking to leverage branding, social media, and website design as potent tools to enhance their market position and financial success.
3. Definition
What is a composite?
• A composite material is made by combining 2 or more
distinct materials to give an unique and better
combination of properties.
• Distinct materials:
- Different at the molecular level (chemically
dissimilar) and mechanically separable.
- In bulk form, the constituent materials work
together but remain in their original forms (separated by a
distinct interface)
• Constituents: Matrix and reinforcing phase
4. Composite Characteristics
Advantages:
• Low density
• High specific stiffness (stiffness-to-density ratio)
• Very high specific strength (strength-to-density ratio).
• Much higher fatigue strength
• High corrosion resistance
• Design flexibility
• Good impact properties
• Noise, vibration, and harshness characteristics are better for
CM than metals
9. Fiber-reinforced composites
• Are the most important composites
• Design goals:
- Low density;
- High specific strength;
- High specific modulus.
• Constituents: - Fibers and matrix
- Agents, coatings.
10. Fibers
• Characteristics:
- Principal constituents;
- Occupy the largest volume fraction;
- Share the major portion of the load acting.
• Design considerations:
- fiber type, fiber volume fraction, fiber length, fiber
orientation.
• Some common fiber types:
- Glass fiber, carbon fiber, aramid fiber, boron fiber,
ceramic fiber, etc.
12. Matrix
• Roles:
- Keep fibers in place;
- Transfer stress between fibers;
- Provide a barrier against an adverse environment
(chemicals, moisture)
- Protect the surface of fibers (by abrasion)
- Minor role in the tensile load-carrying capacity, but major
influence on the compressive, inter-laminar shear, in-
plane shear, buckling, etc.
• Types of matrix:
- Polymer matrix, metal matrix, ceramic matrix
13. Polymer matrix
• Thermoset vs Thermoplastic
• Thermoset (resins):
- Examples: epoxy, polyester, and vinyl ester
- Used as matrix in continuous or long fiber-reinforced
composites
- Molecules are joined by cross-links rigid, 3-D network
structure. Once cross-links are formed, it cannot be melted
by heat.
- Long fabrication time.
(curing)
14. • Thermal plastics:
- Examples: PVC, PS, PP
- Individual molecules are not chemically joined together;
- Held in place by Van der Waals bonds and hydrogen bonds
that can be broken by heat;
- Heat-softened, melted, and reshaped as many times as
desired.
16. Glass fiber-reinforced polymer composites
• Glass is popular as a fiber reinforcement because:
- Easily drawn into high-strength fibers;
- Relatively strong very high specific strength
composites
- Inertness with various plastics
- E-glass, C-glass, S-glass
• High strength but not very stiff and rigid enough for some
applications such as: structure members for airplanes and
bridges
• Limited to services temperatures, below 200C ( t
polyimide resins)
• Applications: automotive and marine bodies, storage
containers, industrial flooring, etc.
17. Carbon fiber-reinforced polymer composites
• Carbon characteristics:
- Very high specific moduli and specific strengths (207-
1035 Gpa);
- Retain characteristics at elevated temperatures, high-
temperature oxidation;
- Not affected by moisture, inert with variety of solvents
19. Disadvantages:
- Much more expensive than PMC
- Reactions between matrix and reinforcement at elevated
temperatures composite degradation surface coating
or modifying the matrix alloy composition.
• Applications:
- Aerospace industry: Aluminum-alloy metal matrix
composites
20. Ceramic-matrix composites
Particulates, fibers or whiskers of one ceramic are
embedded into a matrix of another ceramic.
Improve significantly fracture toughness
Fracture toughness is the ability of a material
containing a crack to resist fracture.
• Applications:
- In high-temperature and severe-stress applications :
Components in automobile and aircraft gas turbine engine
21. Carbon-Carbon composites

- Resistance to creep;
- Relatively large fracture toughness;
- Low coefficient of thermal expansion; and high thermal
conductivity
Drawbacks:
- High-temperature oxidation
- Expensive
23. - The hand layup technique
- The industrial manufacturing technique:

Resin transfer molding, etc.
+ Curing
+ Prepreg
26. • Automotive industry
- Glass fiber
• Sporting goods industry
