英文摘要： The rapid increasing in the usage of composite materials in modern civil aircraft including commericial aircraft and general aircraft leads to an immediate and active demand on advanced composite structure repair technologies with high efficiency and reliability and the fundamental theories for composite structure repair.The current shortage in key technologies reservation in civil aviation composite structure repair in China is directly due to the lack of a systematic study on its fundamental theories. It is of immense strategic significance to promote a great-leap-forward development in the key technologies in the composite repair area and to finally break down the monopoly of western countries. This proposal is about a multidisciplinary research on the key theories and technologies in civil aviation composite structure repair, including the study on the theory and methodology for reliable and efficient repair design, the understanding of the curing behavior of materials under the repair environment and its correlation to the repair material properties, the revealing of the essential characteristics and the binding mechanisms of composite repair interface, and finally the experimental substantiation of the theories. All these research work will provide the scientific foundation and key technological support fo
