Aiming at the problems of low stiffness coefficient and poor stability of sports equipment structure, a new stiffness optimization method of sports equipment structure based on carbon fiber composite material was proposed.Carbon fiber composite matrix was selected to optimize the structure of sports equipment. The optimal form, thickness and number of layers of the matrix was obtained through optimizing the carbon fiber composite matrix in the structure of sports equipment. Based on the obtained information and number of layers, the finite element model of the stiffened plate of sports equipment was established, and the relationship between the stability of the stiffened plate of sports equipment and the bending stiffness was analyzed, the optimal stiffness structure in the design space of sports equipment was obtained. The results show that the stiffness coefficient of the optimized equipment is as high as 0.99, the stiffness optimization effect is the best, and the stability of the optimized sports equipment is high, and the optimization process is relatively simple. It can be concluded that carbon fiber composites can be used as one of the best materials for optimizing the structural stiffness of sports equipment.
