Abstract

The structure and physical and mechanical properties of a silicon carbide–based composite material reinforced with metallic fibers were studied. The optimal content of the reinforcing phase was determined, and the fiber surface was modified to improve adhesion to the matrix. Impact toughness, three-point bending strength, and the coefficient of linear thermal expansion were measured. It was found that fiber reinforcement contributes to the redistribution of internal stresses, leading to improved resistance to impact and bending loads. A correlation was revealed between the strength characteristics and the amount  of the reinforcement.
