Composite materials are widely used in automobiles because of their small proportion, large modulus and high strength. In this paper, carbon fiber-epoxy (T300/5222) composite material is used to design the composite automobile wheel hub according to the general principle of laminated plate design. And the hub layer is finished with hypermesh 14.0. The stress and strain of the hub can be analyzed by Hyperworks14.0 according to the three kinds of conditions. Then the maximum stress layer is found out and the strength is checked. The composite wheel hub is compared with the same aluminum alloy hub. The results showed that composite materials of hub can be achieved in hub strength requirements. Because its ultimate stress is bigger than Aluminum Alloy of hub, obviously the strength of composite hub is higher than the Aluminum Alloy of hub. Because of the smaller strain, the impact of performance is better. The composite wheel hub reduces the weight of 11.3%.
