Abstract

A method and a device for producing a component from a fiber composite material. The method includes introducing multiple layers of fibers impregnated with a matrix onto an inner mold, placing a membrane sealed against an outer mold onto the fibers impregnated with the matrix, such that a cavity extending along the shell surface of the outer mold forms between the outer mold and the membrane, and applying a temperature-controllable pressure fluid to the cavity at a temperature greater than the melting point of the matrix and at a pressure greater than the ambient pressure. To produce a component having at least one reinforcing layer, at least one reinforcing layer having fibers oriented in a predominantly parallel manner is placed locally onto a portion of a side of a the base layer facing the outer mold with the aid of an insertion device and a membrane with an average surface roughness of below 1.0 μm, preferably below 0.1 μm, subsequently exerts a set pressure in the cavity on the component.
