2. What is a Composite?
โข Two or more chemically distinct material which when combined have
improved properties over the individual material.
โข Composites can be Natural or Synthetic
โข It is combination of two material
1. Reinforcing phase
2. Matrix phase

Reinforcement fibres Matrix Material Interface
Glass, Carbon Metal Bonding Surface
Orgainc,Boron Ceramics
4. Polymer Matrix Composites
โข It is a composite material composed of a variety of short or
continuous fibres bound together by an organic polymer matrix.
โข Matrix materials are usually Thermosets and Thermoplastics โ
Polyester, Epoxy, Silicon, Rubber
โข Reinforcing fibres are Glass, Graphite, Boron

Reinforced plastics Advanced Composites
5. Metal Matrix Composites
โข It is a composite with at least two constituent parts one being the
metal and other being a metal or material like ceramic or organic
compound
โข It is made by dispersing a reinforcing material into the metal matrix
โข Commonly used matrices are Aluminium, Titanium, Nickel.

10. Conclusion
โข Composite materials have enormous potential, but the composite
industry will need to demonstrate their advantages for each
application and compete with advocates of metals.
โข They will never completely replace metals.
โข There would appear to be significant future opportunities for
composites in the automotive industry, especially if one considers
their potential advantages compared to metals.
