A punch rivet for the attachment of individual components to one another of which at least one component is formed by a workpiece of composite material, the punch rivet having a flange of larger diameter, a rivet section of smaller diameter and a ring-like component contact surface at the side of the flange adjacent to the rivet section and surrounding the rivet section, wherein the rivet section has a ring surface at its free end for the piercing of the two workpieces, with the punch rivet having a central passage which extends over the full length of the punch rivet and wherein the punch rivet has an inwardly directed projection in the region of the rivet section 14.

Methods of joining components to form vehicle assemblies, such as engine assemblies, are provided. The methods include arranging a first component having a first channel defined therein in a mold, arranging a second component having a second channel defined therein in the mold, and aligning the first and second channel to define a pin-receiving channel. At least one polymeric composite pin is inserted into the pin-receiving channel thereby joining the first and second components, wherein an adhesive is disposed adjacent to at least a portion of the polymeric composite pin.

The present invention relates to a sound absorbing and insulating material with improved heat resistance and moldability and a method for manufacturing the same, more particularly to a sound absorbing and insulating material having, as a surface layer, a heat-resistant material prepared by impregnating a binder into a nonwoven fabric formed of a heat-resistant fiber stacked on one side of a base layer formed of a conventional sound absorbing and insulating material, and a method for manufacturing the same. The sound absorbing and insulating material of the present invention is a conventional sound absorbing and insulating material has improved sound-absorbing property, flame retardancy, heat-insulating property and heat resistance as compared to the conventional sound absorbing and insulating material, is applicable to parts maintained at high temperatures of 200? C. or higher due to the surface layer and is moldable into a desired shape during the curing of the binder impregnated into the surface layer. Therefore, the sound absorbing and insulating material of the present invention can be widely used in industrial fields requiring sound absorbing and insulating materials, including electric appliances such as an air conditioner, a refrigerator, a washing machine, a lawn mower and the like, transportation such as an automobile, a ship, an airplane and the like, construction materials such as a wall material, a flooring material and the like, and so forth.

A combustion engine is provided that includes an engine block with a fiber material in a resin. The engine block defines a piston bore and a bore liner positioned within the piston bore and includes a substrate and a coating positioned on an interior surface of the substrate. An exterior surface of the substrate defines a retention feature.

A manufacturing method includes: forming a tubular portion of a rack housing by press forming from prepregs formed by stacking fiber-reinforced composite materials obtained by impregnating fiber sheets with a thermoplastic resin; and thereafter injecting a thermoplastic resin containing fillers for injection molding to form coupling portions integrated with metal rings. A rack housing is manufactured by the manufacturing method described above.

A method for forming a thermoplastic composite component includes forming a composite sheet using an additive manufacturing assembly. The composite sheet includes a thermoplastic continuous-fiber body including a first side surface, a second side surface, and a perimeter edge. The first side surface is disposed opposite the second side surface. The perimeter edge circumscribes the first side surface and the second side surface. The method further includes applying a thermoplastic overmold onto the thermoplastic continuous-fiber body along at least the perimeter edge using an injection molding assembly.

A method of manufacturing a thermoplastic resin molded article having a hollow portion includes setting a molded article (A) premolded from a thermoplastic resin in a first die, forming a melted thermoplastic resin plate (B) in a shape along an inner surface of a second die facing the first die by being attached to the inner surface of the second die by vacuum pressure, welding the thermoplastic resin plate (B) and the molded article (A) only in a predetermined region by mold-clamping the first die and the second die, and forming at least part of an unwelded region as a hollow portion.
