A method for bonding thermoplastic fiber-composite parts comprises providing surface texture on one or both parts being bonded, and/or providing both parts with engagement features. Such surface textures and engagement features have a specific geometry and fiber alignment that facilitate fibrous interlock between the two parts at a bonding interface via in-situ consolidation.

A forming module for forming a composite laminate part over a tool is provided. The forming module comprises a base, a ply carrier control assembly adapted for controlling the position of a flexible ply carrier on which composite resin plies are mounted, and a head section mounted on the base and adapted for automatically forming the composite resin plies from the ply carrier onto the tool.

The present invention relates to a method for producing foam and foam produced thereby. The method for producing foam includes a step for producing foam by kneading and injection molding a first extrusion product and a second extrusion product, wherein the first extrusion product is obtained by extruding a first composition including an aromatic vinyl-based resin, and the second extrusion product is obtained by extruding a second composition including a polyamide resin and a foaming agent.

A system for manufacturing a thermoplastic prepreg includes a double belt mechanism that is configured to compress a fiber mat, web, or mesh that is passed through the double belt mechanism, a resin applicator that is configured to apply monomers or oligomers to the fiber mat, web, or mesh, and a curing oven that is configured to effect polymerization of the monomers or oligomers and thereby form the thermoplastic polymer as the fiber mat, web, or mesh is moved through the curing oven. The double belt mechanism compresses the fiber mat, web, or mesh and the applied monomers or oligomers as the fiber mat, web, or mesh is passed through the curing oven so that the monomers or oligomers fully saturate the fiber mat, web, or mesh. Upon polymerization of the monomers or oligomers, the fiber mat, web, or mesh is fully impregnated with the thermoplastic polymer.

An injection molding process method of a plastic part on a metal shell to form a high-strength combination comprises: forming a molding cavity which is inwardly concave from the outer surface and extending through flanges at periphery of the metal shell to area beneath bridges protruding from flanges, the bridges being removed after the injection molding. A plastic part with slight deformation is in the molding cavity and is tightly combined with the metal shell due to the bridges. The protruding bridges can be removed from the flanges by milling or cutting without damaging the plastic part, thus the plastic part does not require to be remachined, and the appearance of the metal shell is not affected.

The apparatus includes an upper mold and a lower mold that sandwich the metal member and the resin material, and a drive unit that vertically moves an elastic member attached to a molding surface of the upper mold and at least one of the upper mold and the lower mold. A cavity for arranging the resin material is provided by the upper mold 110 and the lower mold. The elastic member is arranged so as to seal the resin material in the cavity.

A mold is for press molding a metal plate and a resin material to produce a metal-resin composite. The mold includes an upper mold and a lower mold that sandwich the metal plate and the resin material. A cavity for arranging the resin material is provided by the upper mold and the lower mold. The upper mold has a recess into which the resin material leaking from the cavity is caused to flow.

A mold for producing a metal-resin composite by press-forming a metal member and integrally molding the metal member that is press-formed and a resin material includes an upper mold and a lower mold that sandwich the metal member and the resin material. The upper mold includes a first press surface for press-forming the metal member and a second press surface for integrally molding the metal member and the resin material. A distance between the first press surface and the lower mold is shorter than a distance between the second press surface and the lower mold.

The object of the present invention is to provide a cleaning agent that is superior in the initial cleaning effect and allows residues to be easily distributed evenly in the next fabricated molded article. The object is achieved by a cleaning agent used for a molding machine and including a thermoplastic resin and a glass wool.

A polymer composite composition for use in high temperature applications such as furnaces, heat shields and aeronautical jet and rocket motors. In a particular application, the disclosed composition is applied to the manufacture of rocket motor cases, or parts thereof, to provide rigid thermal protection (RTP). The polymer composite composition comprises cyanate ester resin, fine lengths of carbon fibre and refractory filler material.
