| 目的 研究高温-真空环境对新型X2101双马树脂基复合材料结构及性能的影响。方法 采用管式炉分别在330，350，370，400 ℃等高温/真空耦合条件下对X2101双马树脂基复合材料层合板进行热老化处理，利用称重法、傅里叶红外光谱仪（FTIR）、万能试验机和动态热机械分析仪（DMA）等测试手段表征分析老化条件对复合材料的质损率、化学结构、力学性能、动态力学行为的影响。结果 复合材料的最高质损率低于4%。在350℃以下，热老化对基体树脂化学结构的影响较小，随着老化温度的升高，储能模量呈现出先增大后减小的趋势；350 ℃热老化10 h后复合材料的力学性能保持率在65%以上。结论 X2101双马树脂基复合材料是一种性能优良的耐高温结构材料，可用于制造在300 ℃高温下服役的航空航天结构件。 |

| Objective To investigate effects of vacuum aging on properties and structure of X2101 bismaleimide (BMI) matrix composites. Methods The X2101 BMI matrix composites were suffered from a high-temperature and vacuum aging in a tube furnace at 330 ℃, 350 ℃, 370 ℃ and 400 ℃. Effects of aging conditions on mass loss ratio, chemical structure, storage modulus and mechanical properties were investigated by weighing method, Fourier infrared (FTIR) spectrometer, dynamic mechanical analyzer (DMA) and universal test machine. Results The maximum mass loss ratio of composites was lower than 4%; thermal aging below 350 ℃ had almost no influence on the chemical structure of matrix resin; the storage modulus firstly increased and then decreased with the increase of aging temperature; the retention ratio of mechanical properties of composites thermally aged at 350 ℃ was above 65%. Conclusion X2101 BMI Matrix Composites is a kind of high-temperature resistant structural material with excellent performance, and can be used to manufacture aerospace structural components servicing at300 ℃. |
