Study on laser irradiation behavior of carbon fiber epoxy composites and preparation of coatings
碳纤维环氧复合材料在航空航天等领域获得了广泛应用,随着激光技术的发展,激光与材料之间的相互作用研究具有重要价值.本文使用高能连续激光对碳纤维环氧复合材料样品进行了激光辐照试验分析,并以有机硅树脂为基料,氮化硼为填料,添加不同含量的聚四氟乙烯(Polytetrafluoroethylene,PTFE)乳液,采用刮涂法在碳纤维环氧复合材料表面制备了新型涂层材料.在 17.1 W/cm2的功率密度下,随着辐照时间的延长,碳纤维环氧复合材料样品损伤程度逐渐增加.制备得到的改性树脂基涂层反射率可达 83.7％,随着PTFE含量的增加,涂层表面孔洞减少,F—C—F键逐渐增强,接触角增加,改善了涂层表面疏水性能.
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.
