  • Patent number: 12134218
    Abstract: Provided is a method of molding, by using a mold, a component including a metal plate and a thermoplastic resin containing a thermoplastic resin arranged on a surface on one side of the metal plate, the mold including at least a movable mold and a fixed mold including a support portion. Specifically, the molding method includes: an arranging step of arranging a premolded metal plate within the mold; a fixing step of fixing the metal plate by pressing the metal plate against the movable mold with use of the support portion; and a molding step including forming a cavity between the fixed mold and the metal plate by closing the mold, bringing the thermoplastic resin into close contact with the metal plate, and forming an exposed portion by exposing the metal plate out of the softened thermoplastic resin with use of the support portion. With this, without leakage of the thermoplastic resin, a joint region to a metal surface of another component can be reliably secured.

  • Patent number: 11597126
    Abstract: A method for producing carbon fiber reinforced resin molded article of the present invention includes press-molding a mixture-made body including carbon fiber and thermoplastic resin to produce the article that is composed of CFRP. The method further includes perforating pores into the mixture-made body, before press-molding mentioned above. As, in perforating, at least the pores are formed so as to penetrate through a hardened part of a surface of the mixture-made body, the article made of the CFRP that does not have poor appearance, such as whitening or marble pattern, can be produced.

  • Patent number: 11230067
    Abstract: A carbon fiber-reinforced resin molded body of the present invention derives from kneaded materials of a thermoplastic resin and a carbon fiber and includes at least a three-dimensional complex shaped region and a substantially flat plate-shaped region arranged in a profile direction. Fluidity of the kneaded materials at predetermined temperature is such that fluidity of the kneaded material forming the substantially flat plate-shaped region is lower than fluidity of the kneaded material forming the three-dimensional complex shaped region, which makes it unlikely to cause defects in ribs, posses, and other portions. Thus, a carbon fiber-reinforced resin molded body with low cost and high strength can be provided.
