Preparation and Micro-scale Detonation Propagation Performance of BTF/NC/GAP Energetic Composites
摘要
Abstract
To expand the design range of micro-booster explosives,four fully liquid explosive inks were formulated by using ben-zotrifuroxan(BTF)as the main explosive with low detonation critical size characteristics and planar-like structure,nitrocellulose(NC)and glycidyl azide polymer(GAP)as binders,and ethyl acetate as the solvent.The BTF/NC/GAP energetic composites were constructed using inkjet printing technology.The microstructure,critical size of detonation,and detonation propagation performance of the composites were systematically investigated.Results show that the main explosives in BTF/NC/GAP compos-ites exist in a flake-like structure with particle size mainly ranges from 1 to 10 μm.The composites have excellent energy storage properties and micro-scale detonation propagation capability,achieving over 90%of their theoretical energy output.The critical size of detonation reaches a minimum of 1 mm×0.102 mm(2%NC/GAP content),while the maximum detonation velocity at-tains 8436 m·s-1(5%NC/GAP content).Moreover,the increased NC/GAP content induces a transition from nano-to micro-scale pores within the composites,enhancing the probability of hotspot formation and improving the efficiency of energy release.At 10%NC/GAP content,the ratio of experimental to theoretical detonation velocity peaks at 94.61%,demonstrating more complete energy release characteristics and stable detonation propagation.关键词
