碳纤维环氧复合材料激光辐照行为及其表面涂层制备研究
Study on laser irradiation behavior of carbon fiber epoxy composites and preparation of coatings
摘要
Abstract
Carbon fiber epoxy composites have been widely used in aerospace and other fields,and with the de-velopment of laser technology,the study of the interaction between laser and materials is of great value.In this pa-per,the carbon fiber epoxy composite was irradiated with high energy continuous laser,and the new coatings were prepared on the surface of the carbon fiber epoxy composite with silicone resin as the base material,boron nitride as the filler,and polytetrafluoroethylene(PTFE)emulsion with different contents.At a power density of 17.1 W/cm2,the damage degree of carbon fiber epoxy composite increases with the extension of irradiation time.The reflectance of the modified resin-based protective coating can reach to 83.7％.With the increase of PTFE content,the holes of the coating are reduced,the F—C—F bond is gradually strengthened,and the contact angle is increased,which improves the surface hydrophobic property of the coating.关键词
