Abstract

A method for producing a component from a fiber-composite material includes introducing a fiber impregnated with a matrix onto the inner mold of a mold space formed between the inner mold and an outer mold, introducing a separating membrane onto the fiber impregnated with the matrix such that a cavity extending along the lateral surface of the outer mold is formed between the outer mold and the separating membrane, supplying a thermal oil to the cavity at a pressure that is greater than ambient pressure such that the thermal oil acts on the separating membrane at the pressure, heating the thermal oil to above a glass transition temperature of the matrix, and cooling the thermal to below the glass transition temperature of the matrix, wherein the pressure of the thermal oil on the separating membrane is kept substantially constant at least during the cooling to below the glass transition temperature.
