    为了探寻氧化剂对四组元HTPB复合固体推进剂力学性能的影响方式和机理,采取对50℃、20℃和-40℃条件下的HTPB推进剂试件单轴拉伸试验结果和拉伸试件断面电镜照片对比分析方法.分析结果表明,氧化剂不同级配、相同级配不同批次及不同固化时间,对四组元HTPB复合固体推进剂相关力学性能有较大影响,同时推进剂的裂断主要表现在氧化剂界面的剥离,细氧化剂颗粒附近存在应力集中.

    In order to explore the influence of oxidant on the mechanical properties of the four component HTPB composite solid propellant, the uniaxial tensile test results of HTPB propellant under the condition of 50℃, 20℃ and-40℃ were taken. The analysis results show that different oxidant, the same gradation of different batches and different curing time, have great influence on the mechanical properties of the four components of HTPB composite solid propellant, at the same time the crack of the propellant is mainly manifested in the oxide interface and the stress concentration is near the particle.
