    摘要: One or more layers of structured thermoplastic polymer are located within the interleaf zones of a preform or prepreg. The structured thermoplastic polymer is a film or membrane formed by: a) dissolving polyethersulfone or polyetherimide in a solvent to form a polymer dope; b) dispersing a curing agent for an epoxy resin in the polymer dope to form a curative-enriched polymer dope; c) casting the curative-enriched polymer dope onto a surface to form a dope layer; and d) removing the solvent from the dope layer to form a layer of structured thermoplastic polymer.
