摘　　要：在5 MPa的轴向压应力条件下对高聚物粘结炸药进行了温湿度试验,结果表明,高聚物粘结炸药在温湿度载荷三种环境因素的共同作用下,模量和破坏强度都发生了比较明显的变化。高聚物粘结炸药经过45℃、65%RH、5 MPa的温湿度载荷多因素老化试验后,密度基本不变,但是当其经过60℃、80%RH、5 MPa的老化试验后,密度下降比较明显。温湿度载荷多因素老化试验后,模量和破坏强度在老化初期下降都比较明显,但是随着时间的延长,模量和破坏强度变化都不明显。The temperature-humidity environmental tests under 5 MPa axial compression stress were applied to polymer bonded explosive（PBX）. Results show that the mechanical properties of the explosive change obviously after the tests. The explosive density has no change under the conditions of 45 ℃ , 65% RH, 5 MPa, while it decreases obviously under the conditions of 60 ℃ , 80% RH, 5 MPa. In addition, the modulus and the compressive strength all decrease obviously in the early aging time after the temperature-humidity-load accelerating age tests, but they have no obvious change as the aging time goes on.
