Abstract: Bicycle rim with moderate cost, high safety performance, anti-fatigue and other characteristics can be designed through numerically optimal analysis of bicycle rim with inter-ply carbon/glass hybrid fiber reinforced polymer composites. To simulate the behavior of the composite bicycle rim in service by finite element analysis, it can provide relatively reliable scheme for experiments and minimize the waste of the raw material in experiments, and reduce the cost of design and preparation of the composite rim. In this paper, a bicycle rim model was constructed by adjusting the order of carbon fiber prepreg and glass fiber prepreg, the proportion and order of each ply orientation, and the mechanical properties of the rim in service were calculated by the software ABAQUS. The optimal layup scheme was obtained by comparing each scheme of the simulated composite rim in service. The results of accelerated fatigue test (50 000 times) demonstrate that selecting the optimal lay up scheme of rim sidewall and rim bead to make the composite bicycle rim can significantly improve its anti-fatigue capability.
