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