Abstract

A molded part and a method for producing the molded part. The molded part is rotationally symmetrical or at least partially annular in cross section and formed by a plasticized polymeric mass containing fibers being injected through an injection opening into a cavity of a molding tool. Once the polymeric mass has solidified, the molded part is removed from the tool. Injection into the cavity takes place through at least two injection openings in such a way that the fibers are aligned predominantly in the main stress directions of axial tension and torsion in the molded part.
