A method for producing a component assembly for a motor vehicle, wherein the component assembly has a base body for an instrument panel of the motor vehicle and at least one functional component, wherein the at least one functional component is injection-molded to the base body during the production of the component assembly and the component assembly is produced using a gas external pressure process. A component assembly for a motor vehicle is also provided, having a base body for an instrument panel of the motor vehicle and at least one functional component, wherein the base body is produced as an integral injection-molded part together with the at least one functional component using an external gas pressure process. Also, a motor vehicle having a component assembly is provided.

Disclosed is an apparatus for producing a fiber composite preform. The apparatus includes a lower mold and a molding unit for molding a preform by pressing a fiber composite placed on a surface of the lower mold while the molding unit is deformed in accordance with a shape of the surface of the lower mold.

A hot-pressing molding method for fiber thermosetting prepreg material includes providing a die module including a first side die and a second side die; providing an upper die; attaching fiber prepreg material to the upper die with the fiber prepreg material facing the die module; closing the upper die and the die module; heating and pressurizing the upper die and the die module; introducing and pouring a gas with a predetermined pressure through a preset passage into the upper die to soften the upper die so that the softened upper die transmits the predetermined pressure of the gas to the fiber prepreg material. Thus, the upper die applies a lateral pressure to the side wall of the molded product.

A tool element assembly (100) has a tool element (102) with a tool surface (110) and a control surface (112) opposite the tool surface. A thermal control structure (104) is provided defining a flow chamber (103) partially bounded by the control surface, and having an inlet (148) and an outlet (121) which control chamber diverges towards the control surface.

The invention relates to a method for manufacturing a blade made of composite material extending in a main elongation direction, the composite material of said blade comprising a fiber reinforcement densified by a matrix, the method comprising the following steps: a step of weaving warp yarns and weft yarns to produce a fiber preform, the fiber preform comprising at least one warp yarn adapted to form in the matrix at least one first portion of a channel, said portion of length of the warp yarn being directed according to the main elongation direction of the blade and opening at the root of the blade, the first channel portion formed in the matrix by said portion of length of warp yarn constituting at least one first portion of the internal airflow channel; a step of forming the fiber preform so as to produce a blade preform and densifying said blade preform;
characterized in that the weaving step comprises placing at least one second portion of yarn adapted to form in the matrix a second portion of a channel, said second portion of yarn being transversally directed relative to said main elongation direction and opening at the trailing edge of the blade, the second channel portion formed in the matrix by said second portion of yarn constituting also at least one second portion of the internal airflow channel.

A tire mold capable of improving the efficiency in mold production and tire production without compromising the aesthetic quality and performance of a tire after cure-molding. To that end, the tire mold has a hole that penetrates from the molding surface for molding a rubber article to the back surface, a core member that is disposed inside the hole and forms an air discharge flow channel annular in cross section extending along the extension direction of the hole between itself and the hole wall forming the hole, and an interlinking part for interlinking the hole wall and the core member.

A method for producing a component assembly for a motor vehicle, wherein the component assembly has a base body for an instrument panel of the motor vehicle and at least one functional component, wherein the at least one functional component is injection-molded to the base body during the production of the component assembly and the component assembly is produced using a gas external pressure process. A component assembly for a motor vehicle is also provided, having a base body for an instrument panel of the motor vehicle and at least one functional component, wherein the base body is produced as an integral injection-molded part together with the at least one functional component using an external gas pressure process. Also, a motor vehicle having a component assembly is provided.

A mold for forming a wind turbine blade is formed in two halves, each half 1a comprising a sandwich structure of a perforated outer layer, an inner aluminum honeycomb structure and an inner impermeable heat-conducting layer. An article in the form of a mat of glass fiber impregnated with epoxy resin is placed in the mold. A supply chamber 6 supplies heated pressurized air to the mold which passes into the honeycomb core of the mold through the perforated outer layer, and back through the outer layer into two exhaust chambers 7. A row of supply conduits 13 and exhaust conduits 16 connect the exhaust chambers 7 to the supply chamber 6. The air in each conduit 13, 16 is heated by a respective heat exchanger 18 supplied with heated water 9. The heated air cures the epoxy resin, and the mold is then cooled by supplying cold water to the heat exchangers 18, which, in turn cools the air supplied to the mold. The water used to cool the mold is then re-used for the subsequent heating of another article placed in the mold, in order to save energy. Alternatively, the article in the mold may be cooled using a separate supply of air which is not cooled in the heat exchangers 18.

The invention relates to a device for cooling a casting mold (14), comprising an evaporation chamber (18) formed in the casting mold (14), a first pump (23) for supplying a liquid to the evaporation chamber (18), and a second pump (30, 31) for applying a pressure in the evaporation chamber (18), which differs from the atmospheric pressure. The invention also relates to a corresponding method. The invention allows the cooling of a casting mold to be controlled in a targeted manner. This can be helpful in particular in the injection molding of plastic parts.

The invention relates to a tool insert for a primary shaping tool, comprising a thermal insulator disposed on a main part having a molding surface contacted by the molten material to be shaped, said surface being at least partly spaced from the main part of the tool insert by a thermal insulator. The thermal insulator comprises bulk metallic glass.
