本研究針對以HTPB做為膠合劑及IPDI為熟化劑之PBX加入燃燒、爆燃、爆轟抑制劑(DPAs)及以矽烷偶合劑處理RDX等因素進行研究，探討其不同的成份對RDX/HTPB塑合炸藥的熱安定性、相容性、撞擊敏感度及加工性等性質（能）的影響。由此次實驗結果證實以矽烷偶合劑N-(2-Aminoethyl)-3-Aminopropyltrimethoxysilane對RDX進行處理後，因矽烷偶合劑與RDX間形成強烈氫鍵，故不僅提昇塑合炸藥之熱化學安定性、相容性等性質，且有助於藥漿黏度的降低及熟化過程中熟化速率的提昇，在加工性能上亦可獲得顯著的提昇，但攪拌切變速率(shear rate)不同，造成矽烷偶合劑參與熱化反應的程度亦不同，故對藥漿流變性質的影響亦不同。於PBX中加入DPAs，在不影響其熱安定性的情況下，可顯著降低PBX之撞擊敏感性。

Effects of the combustion-deflagration-detonation transition preventing agents (DPAs) on the performance of plastic-bonded explosives (PBX) on the basis of hydroxy-terminated polybutadiene as a binder and RDX as an explosive have been examined in this study. It was shown that the impact sensitivity of PBX can be reduced tremendously on the addition of DPAs. On the other hand, DPAs have only minor effect on the thermal stability of PBX. The silane coupling agent which used to treat the surface of RDX not only improves the interaction between HTPB and RDX but also takes part in the curing reaction, thereby altering the degree of curing during molding. However, these effects are shear-rate and temperature dependent.
