摘　　要：目的为开展某型飞机复合材料预腐蚀后疲劳寿命研究,获取其于加速腐蚀试验环境谱腐蚀和大气环境腐蚀的当量关系。方法编制模拟机场环境的加速腐蚀环境谱,据此分别开展材料试件加速腐蚀试验和大气腐蚀试验,试验过程中观测试件腐蚀形貌,开展两种环境预腐蚀后试件的层间剪切强度性能测试,依据等腐蚀损伤等层间剪切强度性能原则,计算该型复合材料实验室加速腐蚀与大气环境腐蚀的当量关系。结果加速腐蚀试验环境与大气环境对该型复合材料腐蚀存在当量关系,当量折算系数为2.22。结论飞机复合材料于不同环境中的腐蚀当量关系研究应结合研究问题需要,根据不同环境和不同力学性能指标开展研究,不同环境、不同力学性能指标会有不同的当量关系。Objective To carry out fatigue life research on composite material for a certain aircraft after pre-corrosion to obtain the equivalent relation between accelerated corrosion environment spectrum corrosion and atmospheric envi-ronment corrosion. Methods The accelerated corrosion test environment spectrum of airport environment was designed and simulated. Accelerated corrosion test and atmospheric corrosion test of carbon fiber composite material sample were carried out respectively to observe their corrosion morphology. Then the pre-corrosion interlaminar shear strength proper-ties of specimen were tested under different types of corrosion environment. Based on the mechanical property test result and principle of equal damage implying equal life, the equivalent relation between the accelerated corrosion and atmos-pheric corrosion of the carbon fiber composite material was calculated. Results There was an equivalent relation between accelerated corrosion test and corrosion effect of atmospheric environment on such composite material. The equivalent coefficient between two kinds of test environment was 2.22. Conclusion The equivalent relation between accelerated corrosion test environment spectrum and atmospheric corrosion environment of composite material should be analyzed based on the request of research object, that is to say, different environment and different mechanical performance index means different equivalent relation or equivalent coefficient.
