Analysis for Isostatic Pressing Process Safety of a CL-20 Based Composite Explosive
摘要
Abstract
In order to ensure isostatic pressing process safety during the explosives charge , the inherent safety of a CL-20 based composite explosive (GMD-15) and the compatibility between GMD-15 and the contacted media have been analyzed .Numerical simulation , mechanical testing and thermal safety performance testing have been performed to analyze the force safety and thermal safety in the isostatic pressing charging process .Numerical simulation results show that under 140 MPa isostatic pressing the GMD-15 grain temperature rises 7 ℃, which is less than in normal pressing process ( 29℃) .In mechanical properties test , applying stress rate larger than 5 MPa/s to GMD-15 grain prevented it from exploding or burning.In thermal safety performance test , with the heating rate of 1.5-2.0℃/min, GMD-15 powder started with the reaction at 190 ℃, while when GMD-15 grain was maintained at 108 ℃for 3 h, no reaction happens .In conclusion , the isostatic pressing process of GMD-15 is safe and would not lead to the occurrence of thermal explosion .关键词
