Molecular dynamics（MD）was performed to simulate and calculate the combination energy and static mechanical properties（i. e. elastic coefficient,modulus and poisson's ratio）of composite material,1,3,5-triamino-2,4,6-trinitrobenzene coated with polychlorotrifluoethylene（TATB / PCTFE）. It is found that the intermolecular interaction especially H-bond is quite strong. The results show that the elastic properties of Fluorine-Polymer Bonded Explosive（PBX）have changed much compared to those of pure TATB. Its tensile modulus,bulk modulus and shear modulus are reduced evidently. The rigidity of PBX is lowered while the elasticity is increased,which manifests the mechanical property of PBX is improved greatly. 相似文献

TATB/聚三氟氯乙烯复合材料力学性能的MD模拟 总被引：2，自引：0，他引：2
用分子动力学(MD)方法,对聚三氟氯乙烯(PCTFE)在1,3,5 三氨基 2,4,6 三硝基苯(TATB)晶体表 面的行为进行模拟计算,求得结合能和静态力学性能(弹性系数、模量和泊松比).发现以氢键为主的分子间相互 作用相当强.TATB基氟聚合物粘结炸药(PolymerBondedExplosive,PBX)较TATB单体炸药的力学性能改变很 大,拉伸模量、体积模量和剪切模量均减小,表明刚性减弱,弹性增强,力学性能显著改善. 相似文献
