Question

The principal applications of composites are in transportation industry, consumer products and industrial and scientific equipment.

(a) True

(b) False

I got this question during an internship interview.

This is a very interesting question from Polymeric Composites topic in division Polymers of Engineering Chemistry I

Answer 1

Right answer is (a) True

Explanation: The principal applications of composites are in transportation industry, consumer products and industrial and scientific equipment. But composites can fail on the microscopic or macroscopic scale. Compression failures can occur at both the macro scale or at each individual reinforcing fiber in compression buckling. Tension failures can be net section failures of the part or degradation of the composite at a microscopic scale where one or more of the layers in the composite fail in tension of the matrix or failure of the bond between the matrix and fibers.
