激光系统技术的最新进展使碳纤维增强塑料（CFRP）加工的创新技术成为可能。一个典型的应用是逐层去除受损的复合材料，以提供用于用修补层片重新填充的空腔。结果表明，可以实现可靠且可自动化的去除率来执行任意修复腔体几何形状，从而相对于传统的手动研磨过程获得相关的时间缩短。现代紫外激光光源与扫描技术相结合，可实现高达2 m/s的偏转速度，抑制热影响区（HAZ）和纤维从聚合物基体中分离。还提出了一种选择性去除表面基质而不损伤下方纤维的方法。(C)2010年CIRP。
The recent progress in laser system technology enables innovative techniques for machining of carbon fiber reinforced plastics (CFRPs). A representative application is the layer-by-layer removal of damaged composite material to provide a cavity for refilling with repair plies. Results show that it is possible to achieve a reliable and automatable removal rate to perform arbitrary repair cavity geometries, obtaining a relevant time-reduction with respect to the conventional manual grinding process. The combination of modern UV-laser sources with a scanning technology enabling deflection speeds up to 2 m/s, suppresses heat affected zones (HAZs) and detachment of fibers from the polymer matrix. A method for the selective removal of surface matrix without damaging the fibers beneath is also presented. (C) 2010 CIRP.
