Question

What is the main role of matrix in composites! a)-to transfer stress to the other phases b)- to protect phases from environment c)-to reduce the hardness d)-to enhance ductility

Answer 1

Therefore, the options a)-to transfer stress to the other phases b)- to protect phases from environment, are both correct.

Step-by-step explanation:

A composite material is made by mixing two or more materials of different physical and chemical properties. The characteristics of the resulting composite material is different from the properties of the constituting materials.

The two main constituting phases of a composite material is the binder or the matrix and the dispersed phase (reinforcement).

The main function of matrix in a composite is to protect the fibers from any environmental damage and transfer stress to the other reinforcement phase.
