摘　　要：针对固体火箭发动机推进剂/衬层界面,从性能失效、组分迁移、表征方法和在线监测四方面综述了界面贮存性能研究进展。首先,从界面脱粘和裂纹扩展两方面讨论界面贮存性能失效,提出有必要探索准确获取界面性能参数的方法和发动机层次的界面裂纹扩展试验方法,以完善发动机界面性能失效分析体系。其次,分析增塑剂和安定剂等不同组分的迁移机理,认为分子动力学模拟能降低组分迁移机理研究的成本。如能进一步与组分迁移抑制的工程经验相结合,建立完整的界面组分迁移模拟和评价体系,对组分迁移机理研究具有重要意义。再次,从宏观、细观和微观多个层次讨论了界面贮存性能的表征问题,提出应构建“宏观-细观-微观”的跨尺度综合表征体系,由浅入深,从不同尺度和不同特性全面表征界面贮存性能。最后,分析了实现界面贮存性能在线监测的主要技术途径,指出集成化、微型化和适应性是界面在线监测需要攻克的关键技术。Focusing on the solid rocket motor propellant/liner interface, research progress on the interface storage properties was reviewed from four aspects: performance failure, component migration, characterization methods and on-line monitoring. The performance failure was firstly discussed from two aspects: interface debonding and crack propagation. The methods of accurately obtaining interface performance parameters and the test methods of interface crack propagation at engine level should be explored, aiming at improving the failure analysis system of engine interface performance. Secondly, the migration mechanism of different components, such as plasticizer and stabilizer, was analyzed. The research cost for revealing the component migration mechanism might be reduced by molecular dynamics simulation. Combining with the engineering experience of component migration inhibition, together with establishing a complete interface component migration simulation and evaluation system, would be significant to study the mechanism of component migration. Thirdly, the characteristics of interface storage properties were discussed from macro, meso and micro levels. A cross-scale comprehensive characterization system of “macro-meso-micro” should be constructed to characterize the storage properties of the interface from different scales and different characteristics. Finally, the main technical approaches for on-line monitoring of interface storage properties were analyzed. Integration, miniaturization and adaptability were key technologies which should be overcome.
