FIBER-REINFORCED COMPOSITE MATERIAL AND PROCESS FOR PRODUCING FIBER-REINFORCED COMPOSITE MATERIAL

摘要

A fiber-reinforced composite material which comprises carbon fibers and a resin, wherein the carbon fibers have crimps and have been entangled and the fiber volume content is 30 to 80%. The fiber-reinforced composite material combines quasi-isotropy with a high fiber volume content and has little unevenness in mechanical property.
