Cure path dependency of static and dynamic mode II interlaminar fracture toughness of interlayer toughened composite laminates

Faster cure cycles are desirable to achieve higher production rates for thermoset prepreg composites. This work studies the effect of cure cycle on the static and dynamic Mode II interlaminar fracture toughness (GIIc) of an interlayer toughened thermoset prepreg composite, Toray T800SC/3900-2 B. Unidirectional laminates with different interlayer microstructures were manufactured to the same degree of cure using cure cycles with varying heating...
