Effect of Water Immersion on Fiber/Matrix Adhesion

Abstract

A study was made on the effect of water immersion on fiber/matrix adhesion in composites. Representatives of the four main classes of continuous fiber composites were tested: glass/thermoset, carbon/thermoset, glass/ thermoplastic, and carbon/thermoplastic. Water conditioning was done by immersion in 50 deg C distilled water. The only class of composites degraded by water was glass-reinforced thermoplastics. However, carbon-reinforced vinyl esters, a subset of the carbon/thermoset class, appear to have weak fiber/matrix bonds when dry, and these bonds are further degraded by water. In both cases, immersion in water hydrolyzed the interfacial bonds and caused large, irrecoverable property reductions.
