摘要： A method is provided for producing a fiber-reinforced plastic component, in particular for use in a motor vehicle. The method includes the acts of: providing a blow-molded hollow core, forming the fiber-reinforced plastic component on the hollow core; inserting an end of the hollow core between a first roller and a first counter element, and drawing the hollow core from the plastic component by rotationally driving the first roller.

摘要： A process for producing a composite part includes (a) applying a loose carbon filament to a receiving portion of a first mold piece; (b) reversibly coupling the first mold piece with at least a second mold piece to form a first mold layer, wherein an interior region of the first mold layer includes a pocket configured to receive a curable resin, the pocket having a shape of the composite part; (c) infusing the curable resin into the pocket; and (d) curing the resin to form the composite part.

摘要： In the present disclosure, a method may include forming a three-dimensional composite fiber pre-form by three-dimensionally weaving a plurality of composite fibers. The composite fiber pre-form includes a plurality of open cells formed adjacent to and interlocked with each other, and a composite fiber forms at least a portion of a first side of a first open cell and at least a portion of a second side of a second open cell. The first open cell and the second open cell are adjacent to and interlocked with each other.

摘要： A method and system for forming a self-sealing volume includes an elastomeric composite structure. The structure includes layers of a cast polyurethane derived from a neat polyurethane monomer reaction mixture that does not substantially react at room temperature. The polyurethane monomer reaction layer includes a reaction product of an organic polyisocyanate and a reactive hydrogen-containing material reacted with a mixture of a monomeric polyol and polymeric polyols. The structure may further include one or more layers of a fabric that have been precoated with an aliphatic polyurethane, and one or more sealing layers. A fuel impermeable inner liner may be positioned in an inner region. The sealing layers may comprise at least one of partially vulcanized natural rubber (NR), polyisoprene (IR), styrene butadiene (SBR), or a blend of SBR with NR or IR. A dimensionally correct, self-sealing volume may be created by inflating the volume during its cure.

摘要： A process for resin transfer molding (RTM) with injection and overflowing of a resin through one or more troughs is provided that includes the injection of resin into a plurality of injection ports feeding the one or more troughs and overflowing the resin in into a mold. The temperature and pressure are controlled as applied to the mold. The injection ports are activated for injecting the resin in any order of individually, in groups, or pairings. A resin transfer molding (RTM) system for performing the process includes a mold having a cavity. A set of injection ports feed one or more continuous channels between the cavity and a reservoir of resin. A numerical controller selectively activates the injection ports to overflow the resin into the cavity in any order of individually, in groups, or pairing.

摘要： A method for impregnating a fibrous preform by injection or infusion, comprising steps of: —providing a mold having at least two portions, said mold presenting an inlet orifice and a vent orifice placed on opposite sides of the mold; —placing a fibrous preform in a portion of the mold; —placing a thermo-expandable seal in a passage formed between an inside wall of the mold and the fibrous preform, said passage extending substantially along the direction (X) extending between the opposite sides of the mold; —closing the mold; —heating the mold so that the thermo-expandable seal expands and shuts off said passage; and —impregnating the fibrous preform with an impregnation material.

摘要： An ultrasound device for checking the quality of a composite material structure during the production cycle. Preferably, the device is incorporated into a production tooling performing the LRI process in which the composite material structure is placed between two molds during the production cycle. A layer of piezoelectric material is deposited on the face of one of the molds, opposite the face which is in contact with the structure. One face of an electrically insulating flexible material film is placed against the outer face of the piezoelectric material layer. The face of the film further includes conductive pads in contact with the piezoelectric material layer. Each pad is energized by electric voltage applied by a conductive strip. Each pad forms an independent ultrasonic transducer with the region of the piezoelectric material layer opposite of its placement.

摘要： A roof module for a motor vehicle comprises an RTM frame and a Class-A covering layer, which at least partially covers the frame and is made of polyurethane. A method for manufacturing a roof module comprises the following steps: Initially, a fiber mat is put into a first mold. Then, a reactive resin system is introduced into the closed mold and the resin cures, so that a blank is formed. The blank is put into a second mold, into which subsequently polyurethane is introduced in the open condition. The polyurethane expands, wherein it at least partially forms a Class-A surface.
