摘要： A method for the manufacturing of three-dimensional (3D) preforms and composite structures having non-planar surfaces and flanges such that the fibrous or composite material used for shaping the final 3D structure has the necessary length and surface area to conform to the desired contours of the molding tool without wrinkling. The manufacturing method begins with the formation of an intermediate preform blank by automated placement of fiber tapes or prepreg tapes, followed by shaping the blank on a molding tool with 3D contours to form the final 3D structure.

摘要： A tape-laying apparatus includes a material feeder configured to feed tapes, and a laying device configured for picking up and placing tapes onto a laying table. The laying device includes a transporter and a vacuum. The vacuum is connected to the transporter such that at least one tape is configured to be held on the transporter by a negative pressure generated by the vacuum. The transporter includes at least two endless transport belts, which circulate around deflection rollers. The transport belts run parallel to one another in a same transport plane.

摘要： A method for forming a thermoplastic composite material with continuous fiber reinforcement by stamping. A flat blank comprising a pre-consolidated stack of plies by automatic fiber placement of fibers referred to as the thermoplastic pre-impregnated fibers is obtained. The flat blank is reheated to a temperature greater than or equal to the melting temperature of the thermoplastic polymer making up the matrix of the thermoplastic pre-impregnated fibers. The reheated flat blank is hot stamped and the part formed between the stamping punch and die is consolidated.

摘要： There is disclosed a cutting mechanism for severing elongate fiber reinforcement material in composite material lay-up equipment, the cutting mechanism comprising a cutting element and a counteracting element which cooperate to sever fiber reinforcement material extending through the nip between them, the cutting element being mounted on an elongate arm which is pivotable about a pivot axis A spaced from the nip, to displace the cutting element relatively to the counteracting element to perform a cutting stroke, the mechanism further comprising guide means arranged to guide the fiber reinforcement material through the nip in a feed direction transverse to the pivot axis A, and an actuation device for driving the elongate arm in a cutting stroke, the actuation device acting on the elongate arm at a position away from the cutting element. There is also provided composite material lay-up equipment comprising the cutting mechanism.

摘要： Disclosed is a method of forming an article from a unidirectional (UD) tape comprising a continuous unidirectional fiber impregnated with polymer resin. The method includes winding a continuous section of cold UD tape to form a closed loop preform (38) comprising a plurality of stacked layers while discretely welding and consolidating the wound preform by heating and applying pressure.
