Method for producing carbon fiber reinforced resin molded article, and apparatus for producing carbon fiber reinforced resin molded article

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.

FRP MOLDING SYSTEM AND METHOD

An FRP material has a circular arc part, and a member fixed to the circular arc part. The FRP forming system has a portion-pressing device, a member positioning mechanism, and a transport device configured to form the FRP material as a single body of a circular arc-shaped FRP part. The FRP material may comprise a single layer prepreg or a plurality of prepregs that have been layered. The portion-pressing device has upper and lower molds sandwiching a portion of the FRP material in a radial direction orthogonal to the circular arc part, and compresses intermittently a portion of the FRP part. The member positioning mechanism locates the position of the member relatively to the upper or lower mold. The transport device moves the portion of the FRP material that is compressed by the portion-pressing device. The portion-pressing and the transport are repeated to form the FRP part.

LAMINATING AUXILIARY JIG FOR MULTILAYER COMPOSITE MATERIAL AND METHOD OF USING THE SAME
20230067711 · 2023-03-02 ·

A laminating auxiliary jig includes a base having an accommodating recess, and a pressing plate pivotably attached to the base and having a positioning trough. When the pressing plate is opened, it is separated from the accommodating recess, which a first composite material is put into. When the pressing plate is closed, it is located in the accommodating recess and pressed on the first composite material, the positioning trough communicates with the accommodating recess, and at least one middle foam material is put into the positioning trough to be positioned and attached to the first composite material. When the pressing plate is opened again, a second composite material is put into the accommodating recess to be attached to the middle foam material. Therefore, the laminating auxiliary jig helps a user quickly complete laminating the multilayer composite material. The method of using the laminating auxiliary jig is also provided.

Method for manufacturing fiber-reinforced plastic

A method for producing a fiber reinforced plastic can suppress with which wrinkling or bridging in a convex surface or a concave surface having a large curvature at the same time even if the fiber reinforced plastic has a complicated three-dimensional shape. Such methods for producing a fiber reinforced plastic may involve shaping a prepreg sheet in which continuous fibers are impregnated with a resin material into a three-dimensional shape to produce a fiber reinforced plastic (a); wherein at least a portion of the continuous fibers in an area (X) of the prepreg sheet corresponding to an area (X′) in which the fiber reinforced plastic (a) is shear-deformed is bent in an in-plane direction in advance.
