摘　　要：制备了Al/AP/HTPB推进剂和储氢合金/AP/HTPB推进剂,并对它们进行了DSC,PDSC,爆热和燃速测试。DSC和PDSC测试结果表明,储氢合金对AP/HTPB推进剂的凝聚相反应有催化作用,在0.1MPa和5MPa下,使其凝聚相主分解温度分别降低21.67℃和15.67℃,凝聚相反应热分别提高105.97%和21.87%;爆热测试结果表明,储氢合金对AP/HTPB推进剂的气相反应有催化作用,使气相反应热提高4.74%;燃速结果表明,储氢合金可以提高AP/HTPB推进剂的燃速。进一步研究表明,Al/AP/HTPB推进剂和储氢合金/AP/HTPB推进剂的燃速与爆热存在一定的相关性。总结出了燃速-爆热关系式。Al/AP/HTPB propellant and hydrogen storage alloy/AP/HTPB propellant were prepared and their properties were characterized by DSC,PDSC,explosion heat and burning rate test. DSC and PDSC test results show that hydrogen storage alloy has catalysis on condensed phase reactions of AP/HTPB propel- lant in which main decomposition temperature is decreased by 21.67 ℃ and 15.67℃ at 0. 1MPa and 5 M Pa, respectively while condensed phase reaction heat is increased by 105.97% and 21.87% separately. Explosion heat test results show that hydrogen storage alloy has catalysis on gas phase reactions of AP/HTPB propellant in which gas phase reaction heat is increased by 4.74%. Burning rate test results show that hy- drogen storage alloy can increase burning rate of AP/HTPB propellant. Further studies indicate that possible correlation exist between burning rate and explosion heat of Al/AP/HTPB propellant and hydrogen storage alloy/AP/HTPB propellant. The burning rate-explosion heat formula is summed up.
