  • Patent number: 9550331
    Abstract: A method for producing a composite molded part from fiber-reinforced plastics material includes providing a prepreg semi-finished product including fibers that are pre-impregnated with a matrix material and encasing the semi-finished product with a flexible sheet material to form an inner arrangement. The flexible sheet material includes a gas-permeable membrane and an inner planar gas-conducting element. The inner arrangement is encased with a first gas-tight casing and positioned on a molding surface of a mold. The inner arrangement and molding surface is encased with a second gas-tight casing. A first negative pressure is applied to the inner planar gas-conducting element and the inside of the first gas-tight casing, and the entire arrangement is heated for a first time at a first temperature. A second negative pressure is applied to an inside of the second gas-tight casing and the entire arrangement is heated for a second time at a second temperature.
