Effects of Moisture and Fatigue on the Residual Mechanical Properties of S-Glass/Graphite/Epoxy Hybrid Composites

摘要: The static mechanical properties of S-glass/high-strength graphite/ epoxy hybrid composites were investigated before and after exposure to high humidity for 1000 h. Graphite-to-glass ratios 0, ∞, 1, 2 studied. Both unidirectional (0 deg) quasi-isotropic fiber orientations In general, the stress cycling caused a decline in tensile strength, an increase Poisson's ratio, no change whatever elastic modulus base composites. addition moisture did not result basic alteration behavior or cycling.
