Due to the increasing air pollution in recent years, it is necessary to reduce the weight of the vehicle to achieve energy consumption reduction. This study designed and manufactured a new type of stacked composite disc springs. The first stage uses the computer-aided design software Solidworks to design the structure and forming mold of the stacked composite disc spring. Through the finite element analysis software ABAQUS, the direction of the principal stress generated when the disk spring is compressed, and the lamination angle is designed according to the direction of the principal stress. In the second stage, a single composite disc spring was fabricated using carbon fiber and basalt fiber/epoxy composites, the effects of different manufacturing parameters on the physical and compression properties of the single composite disc spring were also investigated. In the third stage, a stacked composite disc springs were fabricated with the best performance manufacturing parameters, and the compression and fatigue properties of the stacked composite disc springs were discussed. According to the research results, the use of carbon fiber composite materials to manufacture stacked composite disc springs can achieve better spring performance, and its fatigue life is about 430,000 times. However, a certain structure in the stacked composite disc spring is more likely to cause stress concentration and cause more serious fatigue damage, so further improvement was needed in the future, so that the stacked composite disc spring has more practical application value.
