TORSION-LOADED ROD-SHAPED COMPONENT WITH DIFFERENT FIBRE REINFORCEMENTS FOR TENSILE AND COMPRESSIVE LOADING

摘要

A torsion spring may be configured as a torsion bar or a helical spring made of a spring wire made of fiber-composite material. The torsion spring may have a plurality of layers of fiber reinforcement that have been saturated with a matrix material, wherein the layers may have fibers that are tension-loaded and fibers that are compression-loaded. The at least one compression-loaded group may have a lower group stiffness than the tension-loaded group with the highest group stiffness. Methods for designing or making torsion springs made of fiber-composite material are also disclosed.
