摘　　要：为改善压伸复合推进剂的力学性能,采取提高黏合剂的相对分子质量、添加不同品种和含量的键合剂、添加不同物态的工艺附加物及高分子增强剂等方法,经改进后,这种高固体含量的压伸复合推进剂在20℃和-55℃条件下的抗压强度和抗冲击强度得到了不同程度的改善。添加高分子增强剂后,推进剂在-55℃条件下的抗冲击强度提高74.3%。In order to improve the mechanical properties of the extrusion composite propellant, through increasing relative molecular mass of binder, adding various bonding agents, technological additives and macromolecular intensifier,the compression strength and impact strength of the propellants with high solid content at 20 C and -55℃ were improved. The impact strength of the propellants with polymer intensifier at -55℃ was increased by 74. 3%.
