CHARACTERIZATION OF BANANA FIBER/PISTACIA VERA SHELL CELLULOSE REINFORCED COM...IAEME Publication
The main objective of the work is to add value to the agricultural residue by fabricating a partially biodegradable composite that shows the best combination of properties. To achieve this, Pistacia Vera shells are opted and cellulose is extracted from it, of both nano and micro sized. Such cellulose is added as filler, to the long banana fibers reinforced polyester composite. Also, this novel material is characterized by testing tensile strength, flexural strength, impact strength and thermal conductivity. Peak Tensile strength for Pistacia Vera shell banana fiber/nanocellulose reinforced composite is found to be 19% higher than banana fiber based composite. Similarly, Flexural, Impact strength and Thermal conductivity results also exhibited good synergism.

Tensile and Flexural Properties of Sisal/Jute Hybrid Natural Fiber CompositesIJMER
During the last two decades using natural fiber as reinforcement in polymers has increased
drastically. The present research work has been carried out to make use of sisal/jute natural fibers. The
aim of this paper is to describe the development and characterization of new set of hybrid natural fiber
composites. It is made by reinforcing sisal/ jute fibers with epoxy resin in matrix by using hand layup
technique. The natural fibers were extracted by retting and combing process manually. Hybrid
composites were prepared using sisal/jute fibers of 0/40, 10/30, 20/20, 30/10, 40/0 weight fraction ratios
while overall fiber weight fraction was fixed as 0.4 weight fraction. The tensile and flexural properties
were carried out using hybrid composite samples. The results indicated that addition of sisal fiber in
jute/epoxy composites up to 50% weight fraction results increasing the mechanical properties

Effect of fibers on Hybrid Matrix CompositesIJERA Editor
Frictional co-efficient, impact quality; dielectric quality and compound resistance examination of bamboo/glass strands strengthened epoxy half breed composites were considered. Two distinctive crossover composites, for example, treated and untreated bamboo filaments were manufactured and impact of soluble base treatment of the bamboo strands on these properties were additionally concentrated on. It was watched that, effect quality and frictional co-proficient properties of the half and half composites increment with expansion in glass fiber content. These properties observed to be higher when salt treated bamboo filaments were utilized as a part of the half breed composites. It is watched that, concoction resistance was fundamentally increments for all chemicals with the exception of carbon tetrachloride.

You can share your opinion in the comment Section.
The natural fibers are renewable, non-abrasive, bio-degradable, possess a good calorific value, exhibit excellent mechanical properties and are inexpensive.
This good environmental friendly feature makes the materials very popular in engineering markets such as the automotive and construction industry.
The banana fibers are waste product of banana cultivation, therefore without any additional cost these fibers can be obtained for industrial purposes.

Viscoelastic response of polymeric solids in sliding contactspadmanabhankrishnan4
Abstract: The viscoelastic response of polymeric solids to sliding contact conditions
is observed and analyzed with respect to the sliding speed, material composition,
and geometry. It was discovered that polymeric solids produced their own distinct
viscoelastic signatures that cause resonance at certain sliding speeds which can be
explained with resonance conditions for electromagnetic waves. The observed viscolelastic phenomenon is characterized with respect to the relaxation and recovery
times for rigid polymeric solids. It is confirmatory as a demonstration of proof of
existence of viscoelasticity and self-organization in these materials under sliding contact conditions. Viscoelastic observations are also made on the aged specimens in
sliding contact.

Composite based on short Agave Americana (Rambaans) fibre (untreated and alkali treated) reinforced epoxy resin using three different fibre length (3 mm, 5 mm, and 10 mm length) are prepared by using open mould technique. The composite thus prepared were subjected to the evaluation of different mechanical properties such as tensile and impact strength. The results obtained suggest that composites reinforced with Agave Americana fibre exhibited better mechanical properties than neat epoxy. All mechanical test showed that alkali treated fibre filled composites withstand more fracture strain than untreated fibre composites.

Material Properties of Chitosan-Based Fibers and Fiber Embedded
Scaffolds
In the United States, nearly 1 in 100 babies are born
with heart defects. Defects such as heart valve
deficiency cannot be treated so easily, causing the
infants to have open heart surgery every year. To settle
this issue, we contributed to a study of chitosan-based
material properties that can be used to engineer tissue
for mechanical heart valves. Chitosan was used
because it is a polyelectrolyte with reactive functional
groups, gel-forming capability, high adsorption capacity
and biodegradability. Chitosan can also go under
several types of modifications. In this study, we used
glycidyl methacrylate (GMA) chitosan fibers with UV
cross-linking. With those fibers, we first tested their
resilience with the tensile testing when the fibers were
dry and hydrated. We then, included the fibers in the
scaffolds and tested the strength of fiber embedded
scaffolds. The objective of the research is to make the
fibers stronger.

•Cross-linked fiber embedded scaffolds are stronger and
stiffer than scaffolds with no fibers.
•Centrifuge chitosan solutions at the speed of 5000rpm.
for 10-15 minutes.
•The rate was 0.5mL/min.
•During cross-linking with the UV lamp, beaker and the
UV lamp were covered with aluminum foil to keep the
concentration of UV light
Fibers were able to be more stiffer and stronger via
cross-linking and thus, cross-linked fiber embedded
scaffolds were stronger and stiffer as well
Future Work
In the future we will make non-woven scaffolds with chitosan
fibers by felting. Then, we will compare the non-woven scaffolds
and cross-linked chitosan fibers. Lastly, we will test both kinds of
scaffolds with cells to evaluate the cell growth on them.
Materials and Methods - Scaffolds
•Centrifuge chitosan solution at the speed of 5000rmp.
for 10 minutes.
•Fill dishes with 5mL chitosan solution.
•The dishes with fibers (figure 1 ) were frozen in dry ice
and alcohol bath for 3 hours.
•For fiber embedded scaffolds (figure 2), fibers were cut
into 2 mm (length) & were layered between chitosan
solution.
•Afterwards, scaffolds were freeze dried for 24 hours.
