摘要
测试了等静压和模压两种工艺成型的JOB-9003炸药在不同温度下的拉伸、压缩及三点弯曲等加载方式下的力学性能,并对两者进行了比较。研究结果表明:两种方式成型的JOB-9003炸药的拉伸、压缩及断裂韧度等力学性能均随着温度增加而降低,在常温下,两种方式成型的JOB-9003炸药的力学性能相当,但在35-55℃范围内,等静压成型JOB-9003炸药的力学性能明显偏高。
It has been tested and compared that the mechanical properties in the load of tension, compress and three-point-bending at the different temperatures of two kinds polymer bonded explosive JOB-9003 which were shaped by technology formation of isostatic liquid and mould pressing. Results show that the mechanical properties of two kinds of JOB-9003 are all most the same at 20℃ , but from 35℃ to 55℃ the mechanical properties of isostatic liquied pressing JOB-9003 is much higher than that of mould pressing JOB-9003.
