Abstract
A fiber composite body, in particular a structure stiffening element, has a number of struts which are formed by reinforcing fibers which are embedded in a polymer matrix and which in a region of the respective strut run substantially parallel to one another. The struts are arranged in a truss-like profiled structure which is produced by winding or intertwining the reinforcing fibers.

-11. (canceled)
A fiber composite body, comprising
- a plurality of struts, wherein the plurality of struts are formed by reinforcing fibers which are embedded in a plastic matrix and which run substantially parallel to one another in a region of a respective strut;
- wherein the plurality of struts are arranged in a trusslike profile structure which is formed by wrapping or stitching the reinforcing fibers.
A method for producing a fiber composite body, comprising the steps of:
- a) providing preimpregnated endless reinforcing fibers;
- b) wrapping the preimpregnated endless reinforcing fibers or stitching the preimpregnated endless reinforcing fibers to a carrier material to form a trusslike profile structure with a plurality of struts, wherein each of the plurality of struts is formed by the preimpregnated endless reinforcing fibers which run substantially parallel to one another in a region of a respective strut;
- c) inserting the wrapped or stitched preimpregnated endless reinforcing fibers into a compression mold;
- and
- d) compressing the inserted wrapped or stitched preimpregnated endless reinforcing fibers to form the fiber composite body.
