Water Exposure of Stressed Graphite Fiber Composites

Abstract

Graphite fiber-epoxy resin composites are tested for their interlaminar shear and flexural strength retention under long-term loading at 50% of their ultimate strengths. Specimens are evaluated in both wet and dry environments. The largest deterioration occurs in the flexural specimens loaded in water. Under this condition, the per cent of strength retained varies from 0 to 81%, depending upon the resin system used.
