摘要
研究了偶联剂对复合推进剂动态力学损耗的影响.建立了一种动态力学分析方法,即通过建立过渡相(或中间相)模型和引入表征因子A,分别在HTPB和聚醚两种体系的复合推进剂中评价了偶联剂的作用效果。结果表明:表征因子A值越低,偶联剂在该温度范围内的作用效果越好.该结论为表征复合推进剂偶联剂的作用效果提供了一种新的方法.
The dynamic mechanical properties of composite propellants with and without a coupling apent were studied as a function of temperature. By establishing a mesophase or interphase model and introducing a characteization factor A, a dynamic mechanical analyis method is presented to evaluate the effeiency of the coupling agents in two kinds of composite propellants. The result is that the lower the value of A, the higher the couping efficiency in a certain temperature range. This investination provides a new method for the characterization of the efficiency of coupling agents in composite propellants.
