| 摘 要： | 研究了三苯基铋（ＴＰＢ）对高燃速丁羟推进剂的催化固化作用。实验结果表明，ＴＰＢ可降低该推进剂的固化温度，缩短固化时间，而且对其加工性能和力学性能都无副面影响，同时还发现ＴＰＢ的最佳剂量是推进剂总量的０．００６％￣０．０５％，在５０℃固化时间为７天。

| Abstract: | The catalysis effect of triphenyl bismuth (TPB) on the cure of HTPBbased high burning rate propellant is investigated. The experimental results show that TPB can reduce the curing temperature and time of the said propellant without any negative effect on its processability and mechanical properties. It is found that the optimal dosage of TPB is in the range of 0.006%0.05% of the total weight of the propellant cured at 50 for a week. |
