摘要： An FRP continuous molding apparatus continuously molds an FRP from a layered sheet that includes prepreg sheets layered over each other. The prepreg sheets each include thermoplastic resin and reinforcement fibers, and differ from each other in fiber orientation. The FRP continuous molding apparatus includes: sheet feeding devices continuously feeding the layered sheets in a feeding direction; a layering device layering, over each other, the layered sheets fed from the sheet feeding devices, and thereby forming a sheet layered body; and a shaping mechanism molding the sheet layered body into an FRP while the sheet layered body is being transferred in the feeding direction. The FRP has a cross section that is a target shape. The sheet layered body includes the reinforcement fibers whose fiber orientation is the feeding direction.

摘要： 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.

摘要： A fiber reinforced plastic (FRP) molding system in which FRP material, having stacked prepregs, is molded to manufacture an arc-shaped FRP component. The FRP molding system comprises inner and outer jig plates, a partial pressing device, and transfer devices. The jig plates are arc-shaped members having outer and inner surfaces that respectively fit with inner and outer surface shapes of the FRP component. The FRP material is sandwiched between the jig plates to form an integrated jig plate. The partial pressing device intermittently compresses a portion of the integrated jig plate in a radial direction orthogonal to an arc of the FRP component so that the FRP component is partially molded. The transfer devices intermittently move the compressed portion of the integrated jig plate by the partial pressing device. By repeating the partial pressing and the transport, the entire integrated jig plate is compressed to form the FRP component.

The outward flange includes: a bonding layer; a foundation layer disposed on the bonding layer; one flange constituting layer having a leg layer which is laminated from one slope surface of the foundation layer to the bonding layer and a wall layer which rises from the one slope surface; and the other flange constituting layer having a leg layer which is laminated from the other slope surface of the foundation layer to the bonding layer and a wall layer which rises from the other slope surface. The foundation layer is formed by laminating roving layers, while the flange constituting layers are formed by laminating a plurality of biaxial fabric layers including a biaxial fabric of a non-crimp structure.

摘要： A joint structure includes a connection member provided between a reinforced member and a reinforcing member and connecting both of them to each other. The connection member includes a first coupling portion and a second coupling portion that are coupled to one and another of the reinforced member and the reinforcing member, respectively. The first coupling portion is coupled to a joint portion of one of the reinforced member and the reinforcing member by an adhesive or welding. The first coupling portion and the joint portion are shaped so as to be caught by each other in a joining direction in which the reinforced member and the reinforcing member are joined to each other.
