测量与理论分析了复合推进剂的黏性与力学性能。实验研究了固体粒子尺寸分布和粘合剂固化比的影响。应用聚合物流变学的理论与概念来模拟推进剂特性。研究得知,细AP粒子在聚合物基体中起有效的填充剂作用,并增强机体的性能。对所研究的推进剂系列配方,当细AP含量接近20%时推进剂可达到最大应变与浇注中的最佳黏性。 Measurement and theoretical analysis of the viscosity and mechanical properties of composite propellants. The effect of solid particle size distribution and binder curing ratio was experimentally studied. The theory and concept of polymer rheology are used to simulate propellant properties. Studies have shown that fine AP particles act as effective fillers in the polymer matrix and enhance the body’s properties. For the studied propellant series formula, the propellant can reach the maximum strain and the best viscosity in casting when the fine AP content is close to 20%.
