复合材料作为一种新型材料以其特有的优点已被广泛应用于航空、航天、建筑、桥梁等领域,复合材料损伤修复已成为热点研究项目。研究以常用复合材料作试件,利用近代光测技术研究了光修复技术对复合材料结构弯曲变形的影响,给出了复合材料结构修复前后刚度变化规律,为光修复技术的进一步研究和应用奠定基础。
As a new type of material, composite materials have been widely used in the fields of aviation, aerospace, construction, bridges and the like for their unique advantages. The damage repair of composite materials has become a hot research project. In this paper, the common composite materials are used as the test pieces. The effects of the optical restoration technique on the bending deformation of the composite structures are studied by modern photometric techniques. The variation of the stiffness before and after the composite structure restoration is given, which will lay the foundation for the further research and application of the optical restoration techniques basis.
