Properties and Residual Stresses in Angle-Ply Polymer Matrix Composites

Abstract

A series of samples of graphite/epoxy, glass/epoxy, and Kevlar epoxy were prepared. In addition, hybrids of glass epoxy and Kevlar epoxy were laid up in various configurations. The samples were subjected to hygro-thermal cycling and properties in the through-the-thickness direction were measured as a function of cycling. Thermal expansion and residual stress measurements were made and the effect of ply orientation was determined on both the hybrid and standard composites.
