Matrix Effects on Interlaminar Fatigue Crack Growth in Composites

Abstract

An experimental investigation was undertaken to study the effects of neat resin properties on interlaminar crack growth of composite laminates under fatigue loading conditions. To obtain a more fundamental understanding of the parameters involved, cyclic crack growth rates were characterized over a wide velocity range for three different resin systems and corresponding laminates using fracture mechanics techniques. Of special importance, the results seem to suggest that the threshold strain energy release rate range, ∆ Gth, in composites under Mode I conditions is controlled by the quasistatic fracture energy, GIC, of the neat matrix resin.
