| 摘 要： | 根据低温液氧贮箱的缠绕工艺与特殊使用环境要求,分别针对3种自制的环氧树脂体系进行系统的工艺特性与低温抗裂纹性能研究。在此基础上以T700纤维复合材料为研究对象,详细考察其在超低温和高低温循环条件下的力学性能稳定性,并对其液氧相容性进行测试。最终以小型碳纤维复合材料筒体进行综合性能验证。研究结果表明,SFC-3环氧树脂具有较好的缠绕工艺特性,且在超低温和高低温交变条件下具有优异的抗裂纹特性。T700/SFC-3环氧复合材料分别经过高低温交变和超低温处理后,拉伸性能保留率在92%以上,且该复合材料具有良好的液氧相容性。T700/SFC-3环氧树脂复合材料筒体具有极好的耐高低温稳定性和气密性。

| Abstract: | According to the requirements of winding technology and special use environment of low temperature liquid oxygen tank, the technological characteristics of three kinds of self-made epoxy resin and the property of low temperature crack resistance were studied. Then, the mechanical properties of T700 carbon fiber reinforced composites were investigated under ultra-low temperature and high-low temperature cycling treatments. Finally, a small carbon fiber reinforced composite cylinder was used for the comprehensive performance test. The results showed that SFC-3 epoxy resin had better winding technology and excellent crack resistance property under ultra-low temperature and high-low temperature cycling treatments. After the aforementioned treatments, the tensile performance retention rates of T700/SFC-3 epoxy composites were above 92% respectively, and the composite material had good liquid oxygen compatibility. T700/SFC-3 epoxy resin composite cylinder had excellent high and low temperature stabilities and gas tightness. |
