摘要

采用30w KrF紫外准分子激光(248 nm)对高性能热塑性CFRP进行表面预处理，以提高涂料的附着力。表面分析表明，热塑性基质没有纤维释放或明显的去除，但有效地去除了硅有机脱模剂残留物。在纳米尺度上的烧蚀产生了清洁效果，提高了涂料的附着力。用溶剂还原涂料系统进行的涂料附着力测试显示，即使在水中或温暖潮湿的条件下长期老化，也有良好的效果。工业聚硫密封胶经紫外光激光处理后，即使不加附着力促进剂也能达到附着力。基于紧凑型紫外准分子激光系统的大规模应用概念显示出高治疗率的机器人引导应用的巨大潜力。

UV-Laser Treatment of Thermoplastic CFRP Parts for Paint Applications

The surface pre-treatment of a high performance thermoplastic CFRP for improved paint adhesion was investigated with a 30 W KrF UV-excimer laser (248 nm). Surface analysis showed no fiber release or visible removal of the thermoplastic matrix but an effective removal of silicon organic release agent residues. The ablation on nanoscale led to a cleaning effect, which improved the paint adhesion. Paint adhesion tests with a solvent-reduced paint system showed good results even after long-term ageing in water or under warm and humid conditions. After UV-laser treatment the adhesion of industrial polysulfide sealants could be achieved even without adhesion promoter. Large scale application concepts based on a compact UV-excimer laser system showed high potential for robotic guided applications with high treatment rates.
