Abstract: A crash protection element, its manufacture and its use are disclosed. The crash protection element is formed by a hollow body element with or from a fiber composite. The hollow body element has in its interior one or more stabilizing and/or compression elements, which are attached on the interior sides of respective front and rear wall elements of the hollow body element in or against a suspected impact direction. The one or more stabilizing/compression elements are constructed either in form of a hollow body or in form of a multi-undulated intermediate wall element.

Abstract: A method for manufacturing a semi-finished textile product, particularly a prepreg, from carbon fibers preimpregnated with a matrix material, includes the steps of manufacturing non-woven fabric having at least 10% carbon fibers and/or a fleece having at least 10% carbon fibers. At least a portion of the fibers used for manufacturing the fabric and/or the fleece are waste fibers and/or recycling fibers. The non-woven fabric and/or fleece is impregnated with a matrix material selected from the group thermoplastic, thermoset, elastomers and any chosen mixtures of two or more of the aforementioned materials.
