Summary

The flexural properties of a series of hybrid laminates, consisting of brittle substrates and carbon fiber/epoxy prepregs, have been examined. Two failure modes have been observed: (i) delamination along the prepreg/substrate interface, followed by frictional sliding, and (ii) cracking of the substrates, followed by tensile fracture of the prepreg layers. A simple model has been developed to describe the stress/strain behavior of the composites when the latter failure mode predominates. The model incorporates the sequential cracking of the various layers and the stress redistribution following each cracking event.
