Three-Dimensional Fiber Skeleton Local Continuous Fiber-Reinforcement through 3D Skeleton Winding Technology

摘要

Continuous fiber-reinforced structural components made of thermoplastic materials are well known on the market and can be produced by large-scale extrusion or injection molding processes.They are usually produced using pre-impreg-nated non-woven or woven fabrics(e.g.unidirectional tapes or composite laminates),which are inserted into a shaping tool and then overmolded.If,however,the continuous fiber-reinforcements are to be used only locally and with a specific fiber direction,the flat tapes and composite laminates must be draped or formed before processing in accordance with the component geometry and the load paths.The more complex the structure,the more difficult it is to form flat reinforcing semifinished products and to use them in components.
