四种含能晶体微观力学性能与摩擦性能的关系
|
摘要
利用纳米压痕技术研究了RDX、HMX、CL-20、TKX-50四种含能晶体的微观力学性能(弹性模量与硬度);采用炸药颗粒滑移力测量仪器测试了炸药晶体的摩擦系数;并通过GJB772A-97方法602.1得到其摩擦爆炸百分数,探究炸药晶体微观力学性能与颗粒摩擦性能之间的联系。结果表明:四种含能晶体的弹性模量和硬度都偏低,大小排序为TKX-50>CL-20>RDX>HMX,TKX-50具有良好的抵抗变形的能力。四种炸药晶体的摩擦系数依次排序为TKX-50 The micro-mechanical properties(elastic modulus and hardness) of four energetic crystals of RDX, HMX, CL-20 and TKX-50 were studied by nanoindentation technique. The friction coefficient of explosive crystals was tested by explosive particle slip force measuring instrument. The friction sensitivity of energetic crystals was obtained by GJB772 A-97 method 602.1, and the relationship between the micromechanical property and the frictional property of four kinds of energetic crystal was investigated. The results show that the elastic modulus and hardness of the four energetic crystals are low, and the order of size is TKX-50>CL-20>RDX>HMX. TKX-50 has better resistance to deformation. The friction coefficients of four kinds of explosive crystal are sorted in order: TKX-50
