Abstract The effects of a low-modulus high-strain interleaf layer, introduced at the midplane, on unidirectional carbon/epoxy laminates under flexural loading were investigated. The apparent energy-to-fail of the laminates increased significantly whereas the maximum load decreased slightly upon interleaving. Real-time microscopic observations during static flexure tests at the lowest deflection rate indicated a dramatic change of failure mode from the dominantly compressive fracture of the baseline laminate to the dominantly tensile fracture process upon interleaving. Failure modes of interleaved and baseline laminates showed no significant changes with test rate in the deflection rate range of 10−6 to 100 m/sec.
