Abstract
A method for producing a component from a fiber composite. A number of layers of a dry fibrous material are stacked to form a pile, the pile is covered by a thermoplastic film in a gas-tight manner, the inner space occupied by the pile within the film is pumped dry and the layers are fixed to form a preform that is stable during transport, the preform is reshaped, a liquid thermosetting material is inserted into the inner space by infiltration of the fibrous material, and the preform is hardened with the infiltrated fibrous material to form the finished component, the film binding permanently as the surface. The invention also relates to a component produced in such a way, and to a corresponding preform. The production method provides a process-integrated surface finishing of the fiber composite. The surface properties are created by the bound thermoplastic film.
