摘要： A textile fiber-composite material precursor and method for producing a component from fiber-composite material. Aircraft components can be produced from polymer fiber-composite materials, a matrix of which can be a high-performance plastics material such as polyether ketone ketone wherein a reinforcement of a non-crimp fabric of carbon fibers is embedded. Large-area non-crimp fabrics and large-area polymer films can be consolidated while being heated and pressed forming simple components. The flexible textile fiber-composite material precursor includes a stack of woven-fabric tiers from a polymer and of non-crimp fabric tiers from carbon fibers. Since both components are capable of draping, the fiber-composite material precursor can be deposited over a large area on curved shape-imparting surfaces and subsequently be consolidated under pressure and heated to form the fiber-composite material.
