Abstract: A method of manufacturing a composite molded body includes a first step of introducing an FRP base material into a mold via a slit part provided in the mold, and inserting the FRP base material along a mold cavity; and a second step of injecting a molten thermoplastic resin composition A into the mold cavity to form the FRP base material into a three-dimensional shape and integrate the injected thermoplastic resin composition A and the FRP base material. The method makes it possible to easily and accurately mold a composite molded body of which a desired portion is efficiently and accurately reinforced in the same mold.

Abstract: A seat cushion frame for a vehicle includes a composite material containing reinforcing fibers which extend in at least the frame extension direction is integrated with an injection molded thermoplastic resin. The weight of the entire seat cushion frame can be greatly reduced, the rigidity and strength required for each section of the frame can be readily secured, required functions such as submarine prevention or the like, can be fulfilled, the number of components can be greatly reduced, and the overall structure can be greatly simplified.

Abstract: A fiber-reinforced resin structure having a hole into which a connector that connects to another member is inserted, wherein a bearing strength at a part of an inside surface of the hole on which a load from the connector acts, represented by a stress at which displacement of the part of the inside surface of the hole starts increasing even without the load acting on the part of the inside surface of the hole from the connector increasing, is less than a breaking strength of a fiber-reinforced resin constituting that part of the structure.

Abstract: An injection molded body includes a fiber reinforced thermoplastic resin composition formed by combining fibrous filler with thermoplastic resin so that the weight average fiber length in the injection molded body is 300 ?m or more, and the injection molded body has a skin layer, a core layer and a skin layer in this order in the thickness direction. The thickness of the core layer, in which the primary orientation direction of the fibrous filler is 40° or less when the direction perpendicular to the flow direction of the resin composition at the time of injection molding is set at 0°, is 20% or less relatively to the thickness of the injection molded body.

Abstract: A structure for a passenger vehicle interior is a structure for constituting the vehicle interior of a passenger vehicle, is formed in a monocoque structure in which the entire structure from the front side to the rear side of the vehicle interior is integrally formed by a fiber-reinforced resin, has a bowl-shaped structure part which is provided at least on the front side among the front side and the rear side of the structure and which opens toward the rear side, and has a side-wall part formed as a vertical wall that is continuous with the bowl-shaped structure part and extends in a front-rear direction of the structure, at each of both side parts of the structure, and a manufacturing method therefor.

Abstract: A panel for a truck having an FRP plate including a woven fabric of reinforcing fiber as a main rigid member, a cargo compartment for a truck using the panel and a truck equipped with the cargo compartment for a truck. The panel and the cargo compartment are light, have sufficient rigidity and strength and excellent in processing and fabricating properties.

Abstract: A cargo container which has sufficient strength and rigidity. The container includes side walls, a roof and a base, wherein at least the side walls are made of FRP (fiber reinforced plastics) plates, and wherein adjacent two sides of the plates are made of an integrally formed continuous FRP panel. The cargo container is suited for use in an aircraft, ship, freight train or the like.

Abstract: The invention relates to a brush holding device used in a motor, and a method of assembling a brush holding frame onto a base plate in the brush holding device. In the brush holding device, flanged portions are protruded from both sides of a lower portion of a brush holding frame, and a pair of fixing portions each having a recessed portion substantially identical in shape to a cross-sectional shape of a corresponding one of said flanged portions are provided. The brush holding frame is inserted between the fixing portions while being slid on and along a base plate surface until the flanged portion on both sides of the brush holding frame are respectively fitted to the recessed portions of the fixing portions. Cover portions are provided on the brush holding frame at a level lower than the guide hole so as to cover the fixing portions when the fixing portions and flanged portions are fitted together.

Abstract: A cargo container wherein at least two walls adjacent to each other are constituted using an integrally formed FRP panel, and a cargo container having a sandwich panel including a core and FRP skins as a main rigidity-maintaining member and wherein at least two walls adjacent to each other are formed integrally. The cargo container according to the present invention is light and has sufficient strength and rigidity as compared with a conventional aluminum-alloy container, and can reduce time and cost required for fabrication and production thereof. Further, the cargo container constituted using the sandwich panel including the core and the FRP skins has excellent freezing, refrigerating, cold insulating and heat insulating performances.
