Abstract

In the reported experiments, the influence of hybridization with stacking sequence variation on static stiffness, strength, ultimate strain and residual properties after thermal cycling of graphite/Kevlar 49/epoxy and graphite/S-glass/epoxy angle-ply laminates was investigated. Tensile stress-strain curves to failure and uniaxial tensile properties were determined for all laminates. Theoretical predictions of modulus, Poisson's ratio and ultimate strain were made, based on linear lamination theory, constituent ply properties and measured strength. Reasonably good agreement was found between the theoretical predictions and experimental results. Stacking sequence variation did not show any significant systematic influence on the measured results. Extensive test data are presented and discussed.
