摘　　要：复合固体推进剂是一种以黏合剂体系为连续相,固体颗粒为分散相的高固体颗粒填充比例的复合含能材料,其宏观尺度力学行为强烈依赖于其细观尺度的三维结构。从推进剂细观力学行为角度综述了复合推进剂细观结构的界面特性和复合推进剂细观结构模型,数值分析了复合推进剂细观损伤演化,通过试验验证了推进剂细观损伤与宏观力学性能的相关性,指出了推进剂宏观性能的微细观结构影响机制,分析了目前标准的现状。为高颗粒填充高能固体推进剂的构效关系及配方设计与创制和复合推进剂标准建设提供重要参考。Composite solid propellant is a high filling ratio composite energetic material with a binder system as the continuous phase and solid particles as the dispersed phase.Its macroscopic mechanical behavior strongly depends on the three-dimensional microscale structures.The interface characteristics and microstructure models of composite solid propellants from the perspective of micro-scale mechanical behavior of propellants were reviewed.Numerical analysis is conducted on the micro-scale damage evolution of composite solid propellants,and the correlation between microscopic damage and macroscopic mechanical properties of propellants is verified through experiments.The current status of the standard is analyzed,which provides an important reference for the structure-activity relationship,formulation design and creation of high-particle filled high-energy solid propellants and standard construction of composite propellants.
