SEMICURED RESIN SHEET WITH PATTERN AND PREPARATION THEREOF AND PREPARATION OF FRP MOLDING WITH PATTERN USING SAID SEMICURED RESIN SHEET WITH PATTERN

摘要

PURPOSE: To shorten working time on a mold, to improve productivity and to obtain an FRP molded item with a pattern having high design properties. ;CONSTITUTION: A method for preparation of a semicured resin sheet 6 with a pattern wherein an uncured resin 2 for forming a surface layer is placed in a bulk shape on one end part of the surface of a base film 1 and an end part side of a face with a pattern 3 of a transfer film 4 one face of which is patterned with an ink being soluble in the resin 2 for forming the surface layer is pushed thereon and then, the transfer film 4 is pressed from one end part side of the surface of the base film 1 by means of a roller 5 and is laminated on the resin 2 for forming the surface layer while the bulk resin 2 for forming the surface layer is uniformly drawn and is made into a semicured condition by curing treatment and the pattern is transferred from the transfer film 4 and in addition, if necessary, this transfer process is repeated to make the pattern into a multilayered pattern, and a method for preparation of an FRP molded item with a pattern wherein the semicured resin sheet 6 with a pattern is laminated with the molding material on a mold and is molded by pressing and heating, are provided.;COPYRIGHT: (C)1993,JPO&Japio
