1. A method for producing a component from a fiber composite material comprising:
introducing multiple layers of fibers impregnated with a matrix, which include at least one reinforcing layer and at least one base layer, onto an inner mold within a mold space formed between the inner mold and an outer mold,
placing a membrane sealed against the 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, such that the temperature-controllable pressure fluid acts on the membrane with the pressure,
wherein the at least one reinforcing layer, which is smaller in terms of expanse than the base layer, having fibers oriented in a predominantly parallel manner is placed locally onto a portion of a side of the base layer facing the outer mold with the aid of an insertion device and the membrane, having an average surface roughness of below 1.0 μm, subsequently exerts a set pressure on the at least one reinforcing layer and the base layer to form the component.
