摘要
A fiber reinforced polymer composition is disclosed comprising a reinforcing fiber and an adhesive composition, wherein the adhesive composition comprises at least a thermosetting resin, a curing agent, and an interfacial material, the fiber is suitable for concentrating the interfacial material in an interfacial region between the fiber and the adhesive composition upon curing of the adhesive composition, and the cured adhesive has a resin modulus of at least 4.0 GPa. Also provided is a prepreg comprising the fiber reinforced polymer composition and a method of manufacturing a composite article by curing the reinforced polymer composition. The resulting interfacial region, viz., the reinforced interphase, is reinforced by one or more layers of the interfacial material such that substantial improvements in tensile, compression and fracture toughness may be observed.
