Question

Write a note on ‘Matrix phase’ of composite material.

Answer 1

• Composite materials are combination of two or more materials with significantly different properties than the original materials.
• Composites are made up of Matrix & Reinforcement.
• Matrix is a continuous phase which holds the reinforcement.
• Matrix is more ductile,soft phase.
• It holds dispersed phase and share load.
• It phases the stress to reinforcement via interface but protects the reinforcement fibers.
• Ex.Concrete: Where cement is matrix and sand,stones are the dispersed phase.
