摘要
在-40^+75℃条件下对TATB基高聚物粘结炸药进行了热循环试验,并在试验前后对炸药试件的尺寸、力学性能及爆轰性能进行了测试。结果表明:TATB基高聚物粘结炸药在热循环后尺寸出现了长大,随着循环次数的增加,其尺寸长大的速率明显变缓;由于界面脱粘,其模量、强度和蠕变性能在热循环后也出现了一定程度的下降;热循环试验后,TATB基高聚物粘结炸药试件的孔隙率增大,其冲击波感度略有升高,但其爆速变化不明显。
Thermal cycling tests of TATB based polymer bonded explosives （PBX） samples are undertaken at the scope from -40-75℃. Their dimensions, mechanical properties and detonation performance are also tested before and after the thermal cycling test. The results show that the dimension of TATB based PBX increases with the increasing of cycle number, but the rate of dimension-growth reduces obviously. Because of the surface de-bonding during the thermal cycling test, its modulus, strength and creep properties decrease a little after thermal cycling test. Owing to the void growth during the thermal cycling test, its shock sensitivity increases, but its detonation velocity keeps no change.
