Abstract
The invention provides a method for simultaneously forming a surface texturing pattern (embossed pattern) on the surface of an FRP product when manufacturing the FRP product by hot-pressing a prepreg material. A prepreg materialis a woven sheet formed by weaving a weftand a warpwhich is impregnated with thermosetting resin. A release film laminateformed by sandwiching an adhesive filmbetween release filmsandis placed on a surface to be provided with surface texturing, before subjecting the same to hot-pressing. The softening temperature of the adhesive filmis close to the curing temperature of the thermosetting resin, so as to allow the thermosetting resinto be pushed into the space between hard FRP fibers during hot-pressing and to form the surface texturing pattern on the surface of the member.
