Publication number: 20210023746Abstract: The method includes placing a block-shaped second resin on a backside of a composite sheet within outer edges, the composite sheet being made up of a plurality of stacked fiber sheets impregnated with a first resin and pressing the composite sheet and the second resin by a heated mold, to produce a resin molded article having the composite sheet embedded in a part of a surface of a resin layer of the second resin that extends to sides of the composite sheet. The composite sheet is formed such that a first fiber sheet of the plurality of fiber sheets positioned closest to a front side of the composite sheet is larger than other fiber sheets and covers the other fiber sheets entirely from the front side, when placed inside the mold.Type: ApplicationFiled: April 17, 2019Publication date: January 28, 2021Applicant: PACIFIC INDUSTRIAL CO., LTD.Inventors: Yuya FUKUI, Yoshinari NAITO, Shinichi FURUNO
