The result shows that the fatigue life of interference - fitcomposite joint is greatly longer than that of sliding - fit composite joint ; the fatigue life of interference - fit composite joint is affected highly by interference quantity ; the optimum quantity of interference to the studied joint model is 1 % ~ 1 . 4 % 研究结果表明：复合材料干涉配合接头的疲劳寿命远远高于间隙配合接头的疲劳寿命；干涉量对复合材料干涉配合接头的疲劳寿命有较大影响，所研究的干涉配合模型的最佳干涉量为1 % ~ 1 . 4 % 。
