Abstract
A mold for a production device for production of fiber-reinforced components by means of an injection process is provided. The mold has a mold surface to form a surface of the fiber-reinforced component, the mold surface having a first partial area and a second partial area and in which the mold has an injection area for injection of matrix material into fibrous material situated on the mold surface through the second partial area of the mold surface and evacuation area for evacuation of a mold volume bounded by the mold through the first partial area of the mold surface.
Claims14
A mold for a production device for production of a fiber-reinforced component by means of an injection process, the mold comprising:
- a mold surface configured to form a surface of the fiber-reinforced component, wherein the mold surface is formed from a plurality of rigid partial molds, and wherein the mold surface has a first partial area formed in a first rigid partial mold and a second partial area formed in a second rigid partial mold;
- an injection area configured for injection of matrix material into fibrous material situated on the mold surface through the second partial area of the mold surface;
- and
- an evacuation area configured for evacuation of a mold volume bounded by the mold through the first partial area of the mold surface, wherein the evacuation area comprises a vacuum line extending through the first rigid partial mold in a direction normal to the mold surface,
- wherein a semi-permeable membrane and a puller are formed as the first partial area and as a composite, wherein the semi-permeable membrane is configured for passage of gases and for retention of matrix material, and wherein the puller is configured for removal of the fiber-reinforced component from the mold.
A production device for production of a fiber-reinforced component by means of an injection process, the production device comprising:
- a mold, which includes
- a mold surface configured to form a surface of the fiber-reinforced component, wherein the mold surface is formed from a plurality of rigid partial molds, and wherein the mold surface has a first partial area from in a first rigid partial mold and a second partial area formed in a second rigid partial mold;
- an injection area configured for injection of matrix material into fibrous material situated on the mold surface through the second partial area of the mold surface;
- and
- an evacuation area configured for evacuation of a mold volume bounded by the mold through the first partial area of the mold surface, wherein the evacuation area comprises a vacuum line extending through the first rigid partial mold in a direction normal to the mold surface;
- a vacuum device configured to evacuate the mold volume via the vacuum line;
- and
- an injection device configured to inject the matrix material into the mold volume via the injection area, in order to force a fibrous material into the area of the mold surface within the mold volume,
- wherein a semi-permeable membrane and a puller are formed as the first partial area and as a composite, wherein the semi-permeable membrane is configured for passage of gases and for retention of matrix material, and wherein the puller is configured for removal of the fiber-reinforced component from the mold.
