Summary of Study on Ageing of Composite Solid Propellant

针对复合固体推进剂的老化问题,探讨了复合固体推进剂老化的主要因素;从复合固体推进剂组分的影响、环境湿度、储存温度等方面分析了其影响复合固体推进剂老化的机理;综述了复合固体推进剂贮存寿命的几种预估方法:力学性能法、阿累尼乌斯方程式法、凝胶含量法、傅里叶红外光谱法和动态粘弹法,并对这些研究方法的内容和结果可信度进行了分析。最后对复合固体推进剂老化研究的发展趋势进行了展望。

In the view of the composite solid propellant ageing,the main factors of the composite solid propellant aging were discussed and aging mechanism of the composite solid propellant was analyzed from the influence of the component of solid propellant, environment humidity and storing temperature, several forecast methods of composite solid propellant storage life was overviewed：the methods of mechanical properties, activation energy, gel content, Fourier infrared spectrum analysis and dynamic mechanical analysis. And simultaneously the main content of these methods and the reliability of these results were analyzed. Finally, aging research trends of the composite solid pro- pellant were discussed.
