| 摘 要： | 对单向M40J/5228A复合材料进行了真空热循环试验(93～413K,10-5 Pa),利用MSC.Marc2001有限元分析软件对复合材料内的交变热应力分布进行了数值模拟.结果表明,真空热循环导致的累积残余热应力会引起复合材料出现局部脱粘,并且使复合材料界面层附近出现应力集中. |
| 关 键 词： | 碳/环氧复合材料 真空热循环 应力集中 有限元分析 |

| Abstract: | The vacuum thermo-cycling tests(93 413K,10-5Pa) were carried out on the Uni-directional M40J/5228A composites.The finite element analysis is using MSC.Marc 2001 software.The results show that under the cumulative-thermal-residual stress caused by vacuum thermo-cycling,localized debonding could occur in the interface layers,since stress concentration appears there. |
| Keywords: | carbon/epoxy composites vacuum thermo-cycling stress concentration finite element analysis(FEA) |
