Question

Write a short note on Particle reinforced composites. 

Answer 1

The size of the particle is in dispersed phase are of nearly the same in all directions.
Large particle composites:
In this sub type of composites, particulate phase should have following characteristics:
1. Stiffer and harder as compared to matrix phase.
2. It acts as reinforcing material.
3. It restrains the movement of matrix surrounding to itself.
4. The bond strength between two phases governs mechanical properties of composites.
