| 中文摘要: |
| 目的 考查某推进剂在-10 ℃ 和-28 ℃ 这两个温度下性能随老化时间的变化趋势。 方法 采用低温加速老化试验。 结果 在低温下老化推进剂最大抗拉强度先下降然后逐渐升高,伸长率变化趋势较为复杂。 常温正常拉伸速度条件下伸长率基本在初始值附近波动,低温快速拉伸条件下伸长率直线下降。 结论 低温下推进剂老化力学性能的变化趋势与高温老化不尽相同,造成这种差异的原因可能是老化机理不同所致。 |

| Objective To study the characteristic changing trends of a propellant at-10 ℃ and-28 ℃ . Methods Lowtemperature accelerated aging test method was used. Results At low temperature, the maximum tensile strength of the aging propellant first decreased and then gradually increased. The changing trend of elongation rate was quite complicated. At room temperature and normal tensile speed, the elongation rate fluctuated around the initial value, while at low temperature and rapid tensile, the elongation rate showed linear decrease. Conclusion The changing trends of mechanical properties seemed different during aging at low or high temperature, the cause of which might be the different aging mechanism. |
