| 摘 要： | 采用纳米压痕技术测试并比较研究了两种高聚物粘结炸药(P1、P2)及其两种涂层(C1、C2)在"加载-卸载-恢复"过程中各阶段的表面变形情况及回弹性能.结果表明,这四种材料表面抗变形能力从大到小的顺序是: P1>P2>C1>C2,而回弹性从大到小的顺序则是: C2>C1>P2>P1,其中C1与P1、P2力学性能差异较小,而C2与P1、P2具有显著差异.并采用Boltzmann非线性回归函数对这四种材料表面变形及回弹曲线进行拟合,拟合曲线与试验数据吻合较好,相关系数均大于0.99.

| Abstract: | The surface deformation and elasticity recovery of two polymer bonded explosives(PBXs) coded P1 and P2 and two coats named C1 and C2 during "load-unload-recovery" process were measured by nanoindention technology. The results show that the ability of deformation resistance of the four materials above is P1>P2>C1>C2,however the sequence of elasticity recovery is reverse. There is only tiny difference between C1 and P1,P2,but the difference between C2 and P1,P2 is obvious. That means comparatively C1 matches ... |
