EFFECT OF FIBER GEOMETRY ON STRESS IN FIBER-REINFORCED COMPOSITE MATERIALS, PHASE 1.

Abstract

Five photoelastic models of fiber-reinforced composite material configurations were designed for the purpose of investigating the effects of various fiber end shapes and broken fibers on the shear stress distribution in an elastic matrix. Maximum shear stresses along fiber boundaries in the vicinity of fiber discontinuities are presented. Stress distributions resulting from squareended, round-ended and pointed fibers were found to be similar. Peak stresses in 'broken' fibers were about twice as high, and decreased with increasing gap length between fiber ends. A description of future configurations to be investigated is presented.
