Method for the fabrication of prepregs

摘要

The present invention relates to a process for producing a prepreg (20), comprising the steps of applying a matrix resin (21) on a resin support sheet, bonding a matrix resin-coated surface of said resin support sheet to one surface of a reinforcing fiber woven fabric (20), bonding a protective film to another surface of said reinforcing fiber woven fabric, subsequently applying heat and/or pressure in order to cause said matrix resin to impregnate said reinforcing fiber woven fabric, thus forming a prepreg in which a surface of said reinforcing fiber woven fabric facing said protective film displays a sea-and-island-pattern comprising resin-impregnated portions (island portions 61) where said matrix resin is present at said surface and fiber portions (sea portions 62) where said matrix resin is not present at said surface.
