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.
