摘要: 采用单轴拉伸实验考察了不同含量黑索今(RDX)固体填料对BAMO(聚双叠氮甲基-氧杂环丁烷)-AMMO(聚叠氮甲基-甲基氧杂环丁烷)基推进剂的拉伸力学性能影响。实验结果表明,随着RDX含量的增加,推进剂拉伸强度增加,延伸率减小,在含量为75%~85%时呈现平台效应。采用动态热机械分析(DMA)考察了不同固体填料含量BAMO-AMMO基推进剂的动态力学性能,分析了固体填料含量影响的机理。DMA分析结果表明,推进剂的玻璃化转变温度随RDX含量的变化规律与延生率变化规律一致,RDX含量增加,延伸率增大,玻璃化转变温度升高,损耗角正切值增大。

Abstract: The mechanical properties of BAMO-AMMO base propellants with various amounts of RDX are characterized by using monaxial tensile test. The results show that the tensile stress of BAMO-AMMO base propellants increases and the tensile elongation decreases when the RDX content increases from 70% to 90%, but the change from 75% to 85% is inconspicuous. The effect of the RDX content on mechanical properties of BAMO-AMMO base propellants is analyzed by dynamic mechanical analyzer(DMA).The analysis result of DMA shows that the change rule of glass-transition temperature with RDX content is the same as that of tensile elongation. The elongation increases, the glass-transition temperature rises and the loss tangent (tan δ) enlarges with the increase in RDX content.
