Abstract
The invention relates to a torsion spring, which is preferably designed as a bar spring or coil spring made from spring wire composed of fiber composite material. Said torsion spring has a plurality of layers (Sj) of fiber reinforcement, which are impregnated with a matrix material, wherein the layers have fibers that are loaded in tension and fibers that are loaded in compression. The torsion spring is characterized in that groups (Gk) of layers (Sj) of the same loading direction exist, and the group stiffness of at least two groups, as viewed from the inside out, differs. The invention further relates to a method for designing a torsion spring composed of fiber composite material.
