The present invention pertains to a manufacturing method for thermoforming a fiber-reinforced composite laminate (1). The fiber-reinforced composite laminate (1) includes fiber rovings (2) embedded within a thermoplastic matrix (4). The manufacturing method comprises mounting fiber rovings (2) to a transport frame (5), wherein the mounted fiber rovings (2) are arranged to form a support grid layer (3) that is laterally framed by the transport frame (5), each fiber roving (2) being mounted on both ends under tension to the transport frame (5); placing a matrix material layup of thermoplastic material on top of the support grid layer (3) on the transport frame (5), wherein the tension of the fiber rovings (2) and a density of the support grid layer (3) are configured such that the support grid layer (3) supports the matrix material layup; softening the matrix material layup by heating the support grid layer (3) together with the matrix material layup within a heating station (8); forming a semi-finished composite laminate (1') by pressing the support grid layer (3) together with the softened matrix material layup within a press (6); and consolidating the semi-finished composite laminate (1') to form the fiber-reinforced composite laminate (1).
Description
technical field [0001] The present invention relates to a manufacturing method for thermoforming fibre-reinforced composite laminates. In particular, the invention relates to a manufacturing method for thermoforming fiber-reinforced composite laminates for use in aircraft or spacecraft. [0002] Although applicable to the manufacture of composite laminates for a variety of technical applications, such as for the production of components for land, water or air vehicles, etc., reference will be made to the manufacture of fiber-reinforced composite laminates for commercial aircraft The method describes the invention and the problem on which it is based in more detail. Background technique [0003] In aircraft construction, structural components increasingly consist partially or completely of fiber-reinforced composite materials, such as carbon fiber-reinforced plastics (CFRP). To manufacture covers and / or skins for large fiber reinforced aircraft parts, such as For flaps, ai...
