A series of samples of graphiteepoxy, glassepoxy, 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.
