a) Matrix phase

Functions of matrix phase are as follows

1. To bind reinforcing particle / fibre strongly
2. It acts as medium for distribution of applied load to the dispersed phase.
3. It keeps the reinforcing fibre I proper orientation for the high strength development
4. It prevents propagation of cracks due to its plasticity

b) Dispersed phase

Functions of Dispersed phase are as follows

a) The dispersed phase comprises of fibres, normally with small diameter preferred to bulk ones.
b) Dispersed phase

The dispersed phase comprises of fibres, normally with small diameter preferred to bulk ones. A special type of fibres widely known as Whiskers are used.

Whiskers have following properties

1. They are very thin single crystals
2. They possess extremely large length / diameter ratios
3. They are flaw free
