Method for manufacturing thermosetting fiber reinforced plastic

摘要

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 material 2 is a woven sheet formed by weaving a weft 10 and a warp 20 which is impregnated with thermosetting resin 40 . A release film laminate 100 formed by sandwiching an adhesive film 130 between release films 110 and 120 is placed on a surface to be provided with surface texturing, before subjecting the same to hot-pressing. The softening temperature of the adhesive film 130 is close to the curing temperature of the thermosetting resin 40 , so as to allow the thermosetting resin 40 to 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.
