Abstract

The invention relates to a rod-shaped fiber composite material (400) composed of a matrix (412) and a circular braid (402) embedded into the matrix. To increase the stability of the fiber composite material (400) and also to perform ducting functions for electricity and fluids, the wall of the circular braid is provided with wall chambers (408) which are separated by a phase boundary from the matrix (412) of the fiber composite material (400). These wall chambers (408) lead to inner and outer sections of the wall of the circular braid (402) being spaced apart, which is useful for the stability with regard to flexing and torsional loading in particular. Rod-shaped fiber composite materials (400) according to the invention can be used for creating stable structural components as well as for producing efficiently protected ducts. The invention further relates to an apparatus and a process which are useful for producing fiber composite material according to the invention.
