Correlation between Alternating Temperature Accelerated Aging and Real World Storage of HTPB Propellant
Pages: 50-54
Year: Issue:  1
Journal: Chinese Journal of Energetic Materials

Abstract: 为研究与自然贮存环境相关性较好的推进剂加速老化方法,设计了 HTPB复合推进剂交变温度加速老化试验,在-10~60℃温度范围内,以3种温度变化速率(10 ℃/12 h,20 ℃/12 h,30 ℃/12 h),分别老化3S d,56 d,91 d后对推进剂进行力学性能测试,基于最大伸长率进行了HTPB推进剂加速老化与自然贮存的相关性分析.结果表明,加速老化过程中推进剂抗拉强度变大、伸长率下降,与自...
