    摘要:

    为了掌握TATB基高聚物粘结炸药(PBX)件受热及辐照环境影响后的尺寸稳定性情况,研究了该PBX经高温老化、γ及中子辐照实验后的热膨胀性能。结果表明,经高温55 ℃、65 ℃和75 ℃老化60 d后,该TATB基PBX热膨胀系数出现了下降,且热老化温度越高,热膨胀系数越小,但经一定条件下的γ及中子辐照环境试验后,其热膨胀性能却无明显变化。

    Abstract:

    In order to study the dimensional stability of TATB based polymer bonded explosive(PBX) undergoing heating and irradiation environmental impact, the thermal expansion property of the PBX after high temperature accelerated aging test, γ and neutron irradiation test was studied. Results show that the thermal expansion coefficients of the PBX after aging at 55 ℃, 65 ℃ and 75 ℃ for 60 days decreases, and the thermal expansion coefficients decreased more as the age temperature higher. But the thermal expansion properties of the PBX after γ and neutron irradiation under a certain condition are not obviously changed.
