采用加压技术,研究了压应力和邵氏硬度对一种浇注高聚物粘结炸药( P-1)装药固化后侧隙缺陷的影响,分析了压应力、应变的关系,得到了 P-1炸药加压固化过程中压应力-应变曲线的方程。对采用加压固化的炸药进行了 CT 检测。结果表明:当应变小于3.232%时,压应力低于0.071 MPa,压缩模量2.27 MPa 。当应变大于3.232%时,压应力和模量值迅速上升。固化5~25 h,邵氏硬度由3 HA 增加到59 HA。在初始邵氏硬度为8~24 HA 时,施加14.2 kPa 压应力,应变为1.3%。辅助加压技术可有效消除装药侧隙缺陷。

The influence of compressive stress and Shore hardness on the annular gap defect of a casting polymer bonded explosive ( P-1 explosive)charge after curing was studied using a compression technology. The relationship between stress and strain was an-alyzed. The equation of stress-strain for P-1 explosive compression curing process was obtained. The detection of the explosive was carried out by CT. Results show that the compressive stress is lower than 0. 071 MPa and the compression modulus is 2. 27 MPa when the strain is less than 3. 232% . The values of stress and modulus rise rapidly when the strain is greater than 3. 232% . The Shore hardness of the explosive increases from 3 HA to 59 HA after 5 ~25 h curing. When the initial value of Shore hardness is within 8 ~24 HA and the compressive stress of 14. 2 kPa is imposed on the explosive,the compressive strain is 1. 3% . The auxiliary compression technology can effectively eliminate the annular gap defect of the charge.
