摘要: 复合材料胶接修复技术在飞机金属损伤结构上得到了广泛应用,但修复结构在飞机服役期内仍受多种环境条件的作用。为研究多种环境因素对修复结构的影响,利用碳/环氧复合材料补片,对含穿透性裂纹的LY12-CZ铝合金板进行了双面胶接修复,采用试验的方法研究了这种修复方法的合理性,并通过t检验法,考核了复合环境条件对修复结构疲劳寿命的影响。

Abstract: Bonded composite repairs have been successfully applied to damaged aircraft structure. The repaired structure is still influenced by compound environment factors during service life of the aircraft. In order to evaluate the influence of environment factors to repair structure, carbon composite patches are double adhesively bonded to center-cracked LY12-CZ plate. The rationality of this repair method was evaluated by experiment, and the fatigue life under compound environment factors was examined by t-test method.

Key words: bonded composite repair, aluminum alloy, environment experiment, fatigue test, t-test method
