英文摘要： The project focuses on the research of the damage self-healing and self-diagnosis of composite material used in aircraft, aiming at the problems of near-space aircraft composite structure design large safety margin and conservative affecting the structural lightweight and mini-type. The project creatively puts forward using solar radiation capillary repair reinforcement fiber structure to realize the self-repair structure research and optical fiber neural network intelligent monitoring system composes of the singular bionic structure research. The light-cured repairing liquid will be injected into capillary repair reinforcement fiber. When the structure is damaged the fiber will break. And the fiber will release the light curing repair liquid to the damage area. Under the solar radiation the liquid will be cured and the structure and fiber neural damage will be self-repair. Besides, the structure health states will be monitored by the fiber neural monitoring system. The singularity is that it is not necessary to provide special repair energy and it realizes the structure and neural self-repair only with the help of solar radiation. It greatly improves the performance of materials and service life. It also has many characteristics such as environmental protection, energy saving and efficient. It has light structure and integrated features. At present, there is no relevant research at home and abroad. The research of realizing composite structures self-repair using solar radiation is original innovation, with the independent intellectual property rights. It provides the reliable basis for realizing the near-space aircraft composite lightweight optimization design.
