A method for producing a component from a fibre 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 fibre composite. The surface properties are created by the bound thermoplastic film.
A process for producing a component made of a fiber composite material wherein:
A preform for a component made of a fiber composite material the preform comprising a stack made of a number of sublayers of a dry fiber material, which has been sheathed in a gastight manner with a thermoplastic film, wherein a subatmospheric pressure prevails in an internal space occupied by the stack in the film, and the sublayers have thus been secured so as to be stable during transport.
