2. materials made from two or more constituent materials with
significantly different physical or chemical properties , that
when combined, produce a material with characteristics
different from the individual components.
Composite matrices are widely categorised under 3 categories
1. Metal matrix composite
2. polymer matrix composites
3. Ceramic matrix composites

3. It is composite material with at least two constituent parts,
one being a metal. The other material may be a different
metal or another material, such as a ceramic or organic
compound.
This possess high strength, light weight and high stiffness to
the composite materials.
PROCESS FOR MANUFACTURE
1. Liquid state process
2. Solid state process

4.  increase in the longitudinal Young's modulus as a function of
fiber volume fraction.
 The larger the fiber diameter for a given fiber volume fraction,
the larger the amount of tough, metallic matrix in the interfiber
region that can undergo plastic deformation and thus contribute
to the toughness.
 Good thermal as well as mechanical fatigue properties
APPLICATIONS:
a. Used in making carbide drills
b. used in defence weapons like tank armours
c. used in making jet landing gear etc.

5. 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 materials is a collection of a
large number of polymer molecules of similar chemical
structure. IN the solid state, these molecules are frozen in
space either in a random fashion or in a mixture of random
and orderly fashion.
Methods Of Manufacture:
High Pressure Compression Moulding.
Pressure Bag Moulding.
Injection Molding.
Filament Winding.
Resin Transfer Molding

6.  High strength at low weight

APPLICATIONS:
1. housing for electrical tools,
2. automotive applications,
3. plastic drawers,
4. metal inserts, Etc..

7. Conclusion
Development of graphs for both the tests
Wear test on pin-on-disc
Compression test on hot pressing machine
Specimen preparation
Material selection as polymer composite material

9.  Wear is nothing but removal of material due to any
frictional force.
 The wear test was conducted on pin-on-disc machine
present in the tribology lab.
 The main aim of performing this test was to determine
the wear rate and coefficient of friction of the early
mentioned composite specimen.
 4 samples were taken in order to determine the results
 In the three samples the wear rate increases with the
increase in load on the stainless steel disc.
 But when the load on the 4th sample was high then due
to removal of more metal and action of them as a
lubricant reduces the friction and wear rate

11.  The wear rate gradually increases for this specimen of composite
material while the load is increased. Although the wear rate will
decrease after a certain point of applying load due to the action of
removed particles as lubricant.
 Using fibre flax materials in place of asbestos material for
reinforcement was a better option. As, the use of asbestos will lead to
the emission of toxic gases. These toxic gases are very hazardous in
nature and causes harmful effect on human body such as cancer.
 While the use of fibre flax material will be eco friendly as these
materials are naturally extracted.
 The specimen have good wear resistance capacity but no tensile
strength due to the use of less amount of reinforcement fiber in the
specimen composite
