Optimization of HTPB-Bonding System Used for High-Solid-Containing PBX Based on Properties of Materials

Article Preview

Abstract:

The HTPB-bonding system used for high-solid-containing PBX was optimizied by orthogonal experiment,and three major factors that were viscosity,hardness and curing time were confirmed as mian indexes for measuring properties of bonding system.The optimal variation range for viscosity,hardness and curing time was respectively 100~125 s,20~28 HC and 4~6 days.Through fitting experimental data,the equations of these three indexes were obtained and then changing laws of that were also studied.By sovling these equations,the best values of constitutions were obtained and formulations for bonding system with different plasticizers were optimized.
