The Influence of Light-cured Repairing on the Stiffness of Composite Material

摘要

With the wide application of composite materials in aeronautics industry, the repairing technology of the composite materials has become a much discussed research topic in material science. Adopting the laser speckle photography technology, this paper focuses on the influence of light-cured repairing to the stiffness of composite materials, and the feasibility of light-cured repairing technology with experiment has been prove in the paper. The research results show that light-cured repairing technology has no evident influence on the stiffness of composite materials and therefore this technology is applicable to fast-repairing of damaged composite materials. This research is of great significance to the application of future researching of composite materials.
