본 발명의 주제는, 바람직하게, 섬유 복합 재료를 포함하는 스프링 와이어로부터 비틀림 바 또는 헬리컬 스프링으로 바람직하게 구성되는 비틀림 스프링이다. 상기 비틀림 스프링은 매트릭스 재료로 함침되는 복수의 섬유 보강층들 (Sj) 을 가지고, 층들은 인장 하중을 부여받는 섬유들과 압축 하중을 부여받는 섬유들을 갖는다. 그것은, 압축 하중을 부여받는 적어도 하나의 그룹 (Gk) 이 인장 하중을 부여받는 최고 그룹 강성을 갖는 그룹 (Gk) 보다 낮은 그룹 강성을 가지는 것을 특징으로 한다. 또한, 섬유 복합 재료로 비틀림 스프링을 설계하기 위한 방법이 개시된다. 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.
