COMPOSITE MATERIAL
INTRO BY
Have you ever heard of
composite material?
COMPOSITE MATERIAL
A composite is when two or more different
materials are combined together to create a
superior and unique material with amazing
properties such as
Flexibility
Lightness
Robustness
Just is in nature, man is able to re-create
comparable structure.
The first uses of composites date back to the
1500s B.C. when early Egyptians and
Mesopotamian settlers used a mixture of
mud and straw to make bricks.
This is an insulative and economical composite
building material
Now a days a composite material is a
combination of at least two different material
Reinforcement
Matrix
One which is generally fibrous but axis of
reinforcement which is contained within the
matrix. This matrix maintains the fibers in a
geometric composition.
Thus creating an extra ordinary efficient
material which is:
Light
Robust
Flexible
Competitive
Many different manufacturing processes
have been developed such as:
1. Vacuum molding
2. Infusion molding
3. Low pressure resin injection
4. Compression molding
1. VACUUM MOLDING
of reinforcement pre impregnated with resin.
2. INFUSION MOLDING
with resin for wind turbine blades
3. LOW PRESSURE RESIN INJECTION
for tennis racket
4. COMPRESSION MOLDING
of car body parts
By combining numerous manufacturing
techniques, the aeronautics industry also
relies on these highly efficient composites.
Shaping our surrounding, these extra ordinary
materials also services source of inspiration
for designers.
The ‘big bench’ that is light and robust and 6m
long maintained on two fulcrums only. The
big bench is designed with the help of
polyester board reinforced with the fiber
glass. this model is processed by
Pultrusion.
Using various methods of reinforcement,
fiber glass is impregnated with polyester
resin and continuously pulled through a
heated die which hardened the resin and
simultaneous shaping of it. The fashioned
part is then cut into a required length. The
flexibility of board gives the designers the
ability to bend it into a curved shaped and
at the same time increases the load
capacity considerably. These properties
never before achieved with conventional
homogenous material.

The big bench won the first prize in two
contests organized by JEC.
Everyday manufacturers and designers
encounter challenges with unexpected and
spectacular results like these

In view of sustainable development, new
passing research and technical evolution may
to be explode continuously. Therefore, the
use of natural fibers like Hemp & Ramie,
what should make recycling
of material easier is a
Challenge to be taken up
today in order to meet
tomorrow’s objectives.
