Abstract

The tensile properties of various carbon matrix composites, reinforced with C and SiC fibers, have been evaluated. The objective is to assess mechanics procedures for characterizing the influence of holes and notches. Interpretation has been attempted using large‐scale bridging mechanics, with linear elastic fracture mechanics as one limit and notch insensitivity as the other. Important differences between the materials, associated primarily with the fiber/matrix interfaces and the in‐plane shear strength, have been identified and attempts made to rationalize these differences.
