Abstract
A process for producing hollow fiber-reinforced components includes impregnating fibers with an impregnating material, preorienting the impregnated fibers, passing the pre-oriented fibers through a heated extrusion die to cure the impregnating material and to form a hollow profile and detaching segments from the hollow profile. The process further includes placing a separating film between the impregnated fibers at one position of the hollow profile prior to curing. The separating film prevents the fibers from bonding as the impregnating material is cured. A segment produced in this way is swung open at the position of the separating film. A subassembly is positioned inside the swung-open segment and then adjacent portions of the segment are permanently bonded together.

A process for producing fiber-reinforced hollow components, comprising:
- impregnating fibers with an impregnating material;
- preorienting the impregnated fibers;
- passing the pre-oriented fibers through a heated extrusion die for forming a hollow profile;
- placing a separating film between the impregnated fibers at a selected position along the hollow profile in a direction of extrusion;
- curing the impregnated material;
- detaching segments from the hollow profile;
- opening the segments at the separating film;
- removing the separating film;
- placing at least one subassembly in the open segment;
- closing the segment around the subassembly;
- and
- bonding the segment in a closed condition around the subassembly to form the fiber reinforced component.
A process for producing fiber-reinforced hollow airfoil profile for a motor vehicle, comprising:
- impregnating fibers with an impregnating material;
- preorienting the impregnated fibers;
- passing the pre-oriented fibers through an extrusion die for forming a hollow profile with an outer shape of the airfoil profile;
- placing a separating film between the impregnated fibers at a selected position along the hollow profile in a direction of extrusion;
- curing the impregnated material;
- cutting a section from the hollow profile to form an airfoil profoil segment;
- opening the airfoil profile segments at the separating film;
- removing the separating film;
- placing at least one internal support in the open airfoil profile segment;
- closing the airfoil profile segment around the support;
- and
- bonding the airfoil profile segment in a closed condition around the support to form the fiber reinforced airfoil profile.
