紫外光固化树脂及其复合材料研究进展

REVIEW ON UV CURING RESIN AND COMPOSITES

纤维增强树脂基复合材料(FRP)多采用热固化方式成型,成型周期长,无法满足汽车等领域复合材料结构快速、高效的生产要求。树脂紫外光固化技术具有固化速度快、生产效率高、环保节能等显著优势,可满足FRP大规模工业化生产要求。综合近年来紫外光固化树脂及复合材料领域的研究热点,主要从反应原理、固化动力学、树脂及配方研究、光固化复合材料成型工艺及应用等领域介绍目前的研究现状,对紫外光固化树脂及复合材料的未来发展进行简要展望。

Fiber reinforced polymer（ FRP） composites are usually through thermal treatment cured. However,the long molding cycle of thermocuring process hinders the rapid production,which is critical for the automobile industry. The ultraviolet（ UV） curing process is both highly efficient and environment-friendly,therefore meeting the demands of the mass production of FRP for the automobile manufacturing. In this article,the key points of UV curing for both resins and composites are reviewed. The research progress on the curing kinetics,resin compounding,molding process,as well as the composites fabrication and repair technologies are introduced. At last,a brief prospect on the development trend of the UV-curing resin and composites is proposed.
