摘要: 高固体含量丁羟推进剂在加速老化实验中,用动态粘弹谱仪测得的弹性模量变化与单向拉伸力学性能的变化规律基本相同。根据对三个不同配方的研究表明,利用粘弹谱仪研究推进剂老化和筛选防老剂,方法简便,数据可靠。

Abstract: In the accelerated ageing test of high solid content HTPB propellants,the elastic modulus measured by dynamic viscoelastometer has almost the same varying regulation as the uniaxial tensile stressThe study of three different formulations shows that the method of studying the ageing of propellants and selecting the ageing resistants by use of viscoelastometer is simple and convenient and the data are reliable
