Abstract
RDX/GAP composite energetic material was prepared by sol-gel method and solution crystallization method using glycidyl azide polymer (GAP) and hexamethylene diisocyanate(HDI) as raw materials and T-12 as catalyst. Its structure was characterized by BET method, X-ray powder diffraction and scanning electron microscopy and its thermal properties were analyzed by TG/DSC. Results show that RDX/GAP composite energetic material has nano-grid structure and its surface area is much smaller than that of GAP xerogel. The mean particle size of RDX/GAP composite energetic material is 20-50nm. The thermal decomposition peak temperature of RDX in the composite energetic material is greatly decreased, and the decomposition heat is much higher than that of the physical blend materials.
