FIBER-REINFORCED COMPOSITE MATERIAL FILLED WITH RESIN PARTICLE

摘要

Layered, fiber-reinforced composites comprising a cycloaliphatic epoxy resin matrix and continuous fiber are toughened by including a resinous particulate modifier in said matrix resin within the inter-ply spacing of the layered composite. The method of the invention is particularly effective in providing composite structures having a marked improvement in toughness over similar composites based on other epoxy resins.
