摘要: Abstract Aluminum nanoparticles were added into cyclotrimethylenetrinitramine (RDX) to enhance the laser absorption and lower initiation energy of pulse laser. Polyvinyl acetate (PVA), polyvinyl butyral (PVB), fluororubber (F2314) RDX as binders prepare RDX-based composite explosives with desirable mechanical behavior. The influence aluminum on light absorption, thermal behavior, electron temperature in plasma investigated using reflectance spectroscopy, differential scanning calorimetry, laser-induced breakdown spectroscopy. Results showed that addition could prominently explosives. doped 2.0% be reliably initiated 1.5 J/cm2 (1064 nm, 8 ns). increased 1.7, 2.4 2.9 J/cm2 additions 0.5%, 1.0% F2314 binders, respectively. When PVA PVB 2.0%, couldn’t by radiated surface explosives, absorbed heated high initiate can provide but because heat transmission from was hindered.
