摘　　要：基于共体加热原理,开发新型高效修复碳纤维复合材料损伤的工艺方法,对碳纤维复合材料典型层合结构损伤部位进行修补,并对修补后结构件的力学性能进行测试,采用多尺度分析方法测试高强度织造国产碳纤维复合材料损伤修复结构性能。结果表明,本项目开发的微波修复技术,其修复时长为15 min,是传统修复工艺的10%,且固化度可达99.9%。采用仅增加补片和增加不同尺寸蒙皮的修复方式,仿真结果与试验结果数据及趋势高度重合,通过仿真分析预测全蒙皮修复方法可使修复后强度达到未损伤时的92.6%。研究结果为碳纤维复合材料在服役过程中受到损伤后的快速修复提供了新方法和理论依据。Based on the integrated heating principle,a new efficient repair process for damaged carbon fiber composite materials is de⁃veloped.The mechanical properties of typical laminated structures of carbon fiber composite materials are repaired and tested after the repair operation.Multiscale analysis methods are used to test the structural performance of high-strength home-made woven carbon fi⁃ber composite materials for damage recovery.The results show that the microwave repair process developed in this project lasts 15 mi⁃nutes,about 10%of the traditional repair process,along with a curing degree up to 99.9%.The repair method of adding only patches and adding skin of different sizes is applied,and the simulation results are highly coincident with the trend and data of the experimental results.The simulation analysis predicts that the full skin repair method could achieve a strength of 92.6%of the undamaged carbon fi⁃ber composite materials.This provides a new approach and theoretical basis for the rapid repair of carbon fiber composite materials after their damage in service.
