Abstract
A curable composite laminate having an interlaminar region formed between adjacent layers of reinforcement fibers. The interlaminar region contains soluble polyimide particles that are dissolvable in the one or more thermoset resins at a curing temperature of the curable matrix resin, and insoluble thermoplastic particles that remain as discrete particles in the interlaminar region at the same curing temperature. Such curable composite laminate is capable of high resistance to the propagation of delamination upon curing.
