| 中文摘要: |
| 目的 研究湿热对复合材料粘接修理结构疲劳性能的影响。方法 在表面处理工艺中分别选择KH550和AC130两种偶联剂，设计制备一系列复合材料粘接修理试样。在温度为55 ℃、相对湿度为98%的环境试验箱中湿热处理72 h。测试湿热前后复合材料粘接修理结构的疲劳性能。结果 复合材料粘接修理后，采用KH550、AC130修理试样的疲劳寿命分别是未修理试样的4.3、5.2倍。湿热处理后，相较于未修理试样，采用KH550的修理试样，疲劳寿命提高了3.8倍，而采用AC130的试样为4.6倍。结论 湿热处理导致粘接界面和复合材料补片的性能下降，从而造成疲劳性能降低。采用AC130偶联剂比采用KH550偶联剂能够获得更好的疲劳性能，且湿热后，其疲劳性能下降较少。采用AC130的试样，其裂纹扩展速率比较低。 |

| In order to investigate the effect of hygrothermal treatment on the fatigue property composite bonded repair structures, a series of samples were prepared according to applications of defferent coupling agents (KH550 and AC130). The composite repaired samples were treated for 72 h in the environment test chamber under the condition of 55 ℃ and 98% humidity. The fatigue life and crack growth were investigated before and after the hygrothermal treatment. According to the test data, the fatigue life of the cracked aluminum plate was increased obviously after composite bonded repair. For sample repaired with KH550, the fatigue life became 4.3 times of the unrepaired one. For sample repaired with AC130, it was 5.2 times. The fatigue life became 3.8 and 4.6 times of the unrepaired ones, respectively for the KH550 and AC130 sample. The hygrothermal treatment can lead to obvious decease of the fatigue property. Application of AC130 agent can result in better fatigue property compared with KH550 agent. Also, after hygrothermal treatment, the fatigue life of sample using AC130 agent decreased less, and the crack growth rate was lower, too. |
