摘要
研究了自然贮存和70、60、50℃加速老化下HTPB推进剂的力学性能变化规律。结果表明,2种条件下HTPB推进剂老化规律相同,表现为强度升高、伸长率降低。以最大伸长率为表征参量,结合自然贮存试验结果,得到HTPB推进剂老化性能与温度、时间的关系。
The mechanical performance change laws of HTPB propellant under natural storage and 70, 60, 50 ℃ accelerated aging were investigated. The results show that the aging laws of HTPB propellant under said two conditions are same and all exhibit that the strength increases and the elongation decreases. Using the maximum elongation as the characterization parameter combined with the natural storage experimental results, the relationship between the aging performance of HTPB propellant and temperature, time was obtained.
