Abstract
The surface properties of fillers(HMX,RDX and Adwith various particle size and nitrocellulose(NC)with various content of nitrogen,the interface properties between NC and fillers,and the effects of the surface and interface properties on mechanical properties of less smoke modified double-base propellant containing nitramine and aluminum were investigated. The results show that the surface tension of HMX,RDX and Al increase with the decrease in their particle size. The interface tension between NC and fillers(RDX,HMX and Al) decrease with decreasing the particle size of RDX and HMX,or with the decrease in nitrogen content of NC. The adhesion work between NC andfillers increases with decreasing the particle size of fillers or with decrease in nitrogen percentage of nitrocellulose. And the adhesion work between NC and Al are bigger than those between NC and oxidizersCRDX and HMX). Three kinds of NC couldn t spread spontaneously on the surface of the fillers. When the interfacial tension between NC and fillers is lower and its adhesive work is higher,the higher tensile strength of propellant is obtained.关键词
