CL-20/PVDF/nAl基复合含能微球的燃烧性能调控
Combustion Performance Regulation of CL-20/PVDF/nAl Composite Energetic Microspheres
摘要
Abstract
Micro-nano composite energetic materials have attracted much attention due to their excellent properties and have broad application prospects in the fields of explosives and propellants.The electrostatic spray method,as an emerging composite material preparation technology,has a significant impact on the assembly and energy release regulation of energetic materials.To address the issues of insufficient combustion of micro aluminum powder,low energy release efficiency,and long ignition delay,the electrostatic spray method was used to successfully prepare uniformly mixed hexanitrohexacyclohexylazomethine/polyvinyli-dene fluoride/nanometer aluminum(CL-20/PVDF/nAl)based composite energetic microspheres.These microspheres were further modified with ferric oxide(Fe2O3)and reduced graphene oxide(rGO).The results showed that the samples prepared by the elec-trostatic spray method had a regular morphology,uniform size,high sphericality,and a particle size of approximately 1-7 μm.Compared with the physical mixture samples,microspheres exhibit superior thermal and combustion properties.Additionally,the addition of oxidant Fe2O3 and catalyst rGO can significantly improve the energy release efficiency and combustion performance of the microspheres,and when the content reaches 20％and 4％respectively,the shortest combustion time is 7 ms,the minimum ig-nition delay time is 0.13 s,the maximum equilibrium pressure is 2.17 MPa,and the maximum pressure rise rate is 1.63×104 kPa·ms-1.关键词
