The invention relates to a method for producing a semi-finished product for producing a composite molded part (7), in particular a composite fiber molded part, wherein a higher-melting reinforcement material (8), in particular higher-melting reinforcement fibers are combined with lower-melting fibers (10) made of thermoplastic into a laminate (4), wherein the lower-melting fibers are spun and after spinning are combined at a fiber temperature T.sub.F with the higher-melting reinforcement material, in particular with higher-melting reinforcement fibers, into the laminate forming the semi-finished product. The fiber temperature T.sub.F lies in a temperature range between a temperature of 25 C. below the heat distortion temperature T.sub.W to 55 C. above the heat distortion temperature T.sub.W of the thermoplastic of the lower-melting fibers.

In a gear comprising a resin material including a fibrous filler, a plurality of teeth formed at equal angular intervals are provided to a first outer peripheral part. When the gear is manufactured, the resin material is filled from a specific portion (first toothless part) which faces in a direction orthogonal to a center axis line, and in which the teeth are not formed in a portion that overlaps the first outer peripheral part when seen from the direction orthogonal to the center axis line. Therefore, there is a gate mark in the specific portion. Between the specific portion and the center axis line, the degree to which the filler is oriented in a direction intersecting the center axis line is higher than the degree to which the filler is oriented in a direction running along the center axis line.

The present disclosure describes a composite material that includes a polysulfone aromatic polymer combined with an adhesion promoter, and a reinforcing fiber. The polysulfone aromatic polymer may be a polysulfone aromatic polymer, a polyethersulfone aromatic polymer, or a polyphenylsulfone aromatic polymer. The adhesion promoter may be, for example, a polyamideimide or a polyamide-amic acid polymer. The disclosure also describes a method of making a composite material using a solvent-dissolved polysulfone aromatic polymer and a reinforcing fiber.

A member for chassis is provided. The member for chassis includes a frame part that is made of a thermoplastic resin bonded to at least a part of an external-form end face of a laminated sheet with an intermediate layer arranged between a pair of fiber reinforced resin sheets. The thermoplastic resin that configures the frame part is extended to a surface of the laminated sheet. An opening is provided on the surface of the laminated sheet that has been covered with the extended thermoplastic resin, and the member for chassis includes an anchor part formed by putting the thermoplastic resin into the opening.

A hot press cushioning material (10) of the present invention includes, as a base material, a woven fabric layer (11) using bulky yarn (12) as at least one of the warp and weft, and a nonwoven fabric layer (14) placed on one surface side of the woven fabric layer (11), a part of the nonwoven fabric layer (14) being embedded in the woven fabric layer (11). A nonwoven fabric-resin composite layer (18) is formed in the opposite surface of the nonwoven fabric layer (14) from the woven fabric layer (11) by impregnation with resin (15). A woven fabric-rubber composite layer (19) is formed in the other surface of the woven fabric layer (11) by impregnation with rubber (16). The nonwoven fabric-resin composite layer (18) and the woven fabric-rubber composite layer (19) have voids (17) therein.
