Abstract
A study is made on the features of failure in a fibrous composite material in relation to the volume proportion of reinforcement. Fractographic analysis shows that failure in such a material begins at the matrix-fiber interfaces and is independent of the volume proportion of reinforcing phase, being distinguished by fracture crack propagation occurring in concentric regions of tensile stresses and involving brittle failure in the glass-ceramic matrix. The failure rate at the matrix-fiber interfaces is related to the adhesive strength of the glass ceramic-stainless steel system and the cohesive strength and dissipativeness of the glass-ceramic matrix, and it alters substantially as the volume proportion of the reinforcement increases.
