This PPT is about a composite material our team made by using Banana fibre

1. Banana fiber reinforced
composite material
Kongu engineering college,
Perundhurai,
Erode.

2. Introduction
This paper is about using natural materials instead of
using synthetic materials in composite wall production.
Composites are formed by combining materials together
to form an overall structure that is better than the
individual components.

3. Examples of
composite material
Composite building materials such as cements, concrete.
Reinforced plastics such as fiber reinforced polymer.
Metal composites .
Ceramic composites(composite ceramic and metal
matrices).

4. Synthetic composite
Composite material made of artificially produced
materials are called as synthetic composites .
Glass reinforced plastic, Thermo plastic composite
are some of the examples of synthetic composites
.
These composite materials are commonly used
nowadays .

5. Natural composite
Natural composites exist in both animals and plants.
Wood is a composite – it is made from long cellulose
fibers held together by a much weaker substance called
lignin.
The bone in your body is also a composite.

6. Preparation of banana fiber
reinforced composite wall
 Extract fiber from a plantain stem and yarned it
in to form of thread .

7. Banana Fibre Twist

8.  Align the
prepared thread
from a plantain
,vertically and
horizontally over a
cardboard and
poured the gap
with resin .

9. Resin
Resin used is Poly ester .
 Poly ester tends to have yellowish tint, and is
suitable for most backyard projects.

10. Pictures of resin

11. Comparison

12. Hardener
Hardener we used is methyl ethyl ketone peroxide .
When the peroxide is mixed with the resin ,it
decomposes to generate free radicals, which initiate
curing reaction .

13. Picture of hardener

14. Filler
Filler we used is silicon powder .
Normally filler is used to accompany the pores in
composite material .

15. Prepared composite wall

16. Composition in
percentage
Resin-60%
Hardener -10%
Filler- 30%

17. Properties measured
We checked the tensile strength of the composite
material and it is up to 33 Mpa
Thermal conductivity is less .
Material will not absorb water ,hence this shows the
resistance it will provide during rainy season.

18. Applications

19.  It can be used in
Automobiles for
preparing parts of
vehicles .

20. Advantages of natural fiber
 Environmentally friendly •
 Fully biodegradable •
 Non toxic •
 Easy to handle •
 Non abrasive during processing and use •
 Low density/light weight •
 Compostable •
 Source of income for rural/agricultural community •
 Good insulation against heat and noise •
 Renewable, abundant and continuous supply of raw materials
•

21.  Low cost •
 Enhanced energy recovery •
 Free from health hazard (cause no skin irritations) •
 Acceptable specific strength properties •
 High toughness • Good thermal properties •
 Reduced tool wear •
 Reduced dermal and respiratory irritation •
Ease of separation .

22. Future experiments
To producing this material in sizes near to the sizes
of asbestos sheet .
To test all the properties of the material .
To use calcium carbonate as a filler instead of using
silicon powder.
