| Summary: |
|
- The application of composite materials in aerospace structures has significantly enhanced the comprehensive performance indicators and fuel economy of aircraft. While achieving structural-functional integration, the service reliability of these advanced materials critically depends on the systematic evaluation of multi-scale mechanical properties—from the microscale of fiber-matrix, the mesoscale of interlayers to the macroscale of structures, the multi-level mechanical responses and damage evolution need to be quantitatively characterized through multi-scale analysis methods. In addition, the coupled multi-physics effects induced by complex service conditions, such as extreme thermal cycling, hydrodynamic impacts, and high-rate dynamic loading, will further accelerate the initiation and propagation of structural damage, leading to severe challenges to the load-bearing capacity and service life of composite structures, which urgently need to be solved through scientific optimization design. Interlaminar toughening and structural optimization are core technologies to improve the damage resistance of composites, as important parts of optimization design of composites. These need to be deeply integrated with multi-scale and multi-physics analysis to form a complete system in the field of current aerospace composites.

- 复合材料在航空航天结构中的大规模应用显著提升了飞行器的综合性能指标与燃油经济性。这类先进材料在实现结构-功能一体化的同时，其服役可靠性高度依赖于跨尺度力学性能的系统评估——从纤维-基体微观尺度、层间介观尺度到结构宏观尺度，多层级力学响应、损伤演化的跨尺度传递过程，均需通过精准的多尺度分析方法实现定量表征。此外，在复杂服役工况下，极端温度交变、流体动力冲击、高动态载荷等因素引发的多物理场耦合效应，会进一步加剧结构损伤萌生与扩展，对复合材料结构的承载能力与服役寿命提出严苛挑战，亟需通过科学的结构优化设计予以解决。其中，层间增韧作为提升复合材料抗分层、抗损伤能力的核心技术，是结构优化设计的重要组成部分，需与多尺度多物理场耦合分析深度结合，形成面向航空复合材料领域的完整技术体系，这也是当前航空航天复合材料结构设计优化领域的核心研究方向与重点突破点。
