摘要
采用溶胶-凝胶法,结合超临界CO2流体干燥技术,制备了85%RDX的Fe2O3/Al/RDX含能材料。利用扫描电子显微镜（SEM）对样品进行了表征,其粒度为50~150 nm。对比测试了样品和原料RDX撞击感度、摩擦感度,样品的特性落高比原料RDX（2.5 kg,22.5 cm,12型工具）提高27.7 cm,其爆炸百分数比原料RDX（90°,3.92 MPa,96%）降低88%。含RDX 85%的Fe2O3/Al/RDX含能材料压制成密度为1.55 g·cm-3的药柱,爆速为7185 m·s-1,是一种钝感高能的纳米复合含能材料。
Composite energetic materials that contained 85% hexogen（RDX）,3.75% aluminum and 11.25% iron oxide（Fe2O3） were obtained by sol-gel template and supercritical CO2 fluid drying technology,and characterized by scanning electron microscope（SEM）.Its particle size distribution is from 50 nm to 150 nm.Its impact and friction sensitivity test results show： comparison with raw RDX,the characteristic height（H50） of the sample is 27.7 cm higher than that of RDX（2.5 kg,22.5 cm）,and percentage of explosion is 88% lower than that of RDX（90°,3.92 MPa,96%）.The detonation velocity of the composition is 7185 m·s-1 with 1.55 g·cm-3 pressed density.It is identified as nano-composite energetic materials with insensitivity and high energy density.
