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. %R 10.12044/j.issn.1007-2330.2018.05.007 %U http://www.yhclgy.com/yhclgy/home %1 JIS Version 3.0.0
