Abstract
The present invention relates to a method for producing a fiber-reinforced component, comprising the step of providing a fiber material (2) impregnated with resin, having rovings (4) extending alongside one another at least in one direction. The object of the present invention is to provide a method, with which irregularities in the fiber material impregnated with resin can be reduced or even eliminated. The method is characterized by a step of stretching the fiber material (2), so that the rovings (4) align in their longitudinal direction. Furthermore, the invention relates to a device for carrying out the method according to the invention and to a fiber-reinforced component.
Claims16
A method for producing a fiber-reinforced component comprising:
- providing a fiber material impregnated with resin and having a plurality of rovings adjacent one another extending in at least one direction;
- and
- stretching a section of the fiber material to align the rovings in their longitudinal direction by means of a frictional force is exerted on ends of the rovings that extend in one direction adjacent one another and that project from the resin-impregnated fiber material, wherein the rovings consist of weft and warp filaments, the ends of the rovings being exposed by removing one or more weft or warp filaments running transverse to said ends of the rovings to provide protruding free ends which delimit the fiber material,
- wherein during stretching substantially no vertical compressive force is exerted on the section of the fiber material being stretched,
- wherein the frictional force is generated by a stretching surface of a roller element which is rotated in the longitudinal direction of the rovings to be stretched and the rovings rest freely on the stretching surface of the roller element, and
- wherein at least before and/or during stretching, the fiber material is heated to at least soften the resin.
