碳纤维增强聚合物（CFRP）复合材料粘接前，表层树脂层的去除是必不可少的工作。本文研究了用低功率连续波二氧化碳激光去除CFRP顶层树脂层而不破坏底层纤维的技术可行性。实验确定了操作窗口和损伤阈值。以14W的功率、880mm/sec的扫描速度和25%的光束重叠照射CFRP表面，为去除顶部树脂层提供了最佳的热条件。采用有限元模型解释了其去除机理。
The removal of top resin layer is an essential task prior to adhesive bonding of carbon fiber reinforced polymer (CFRP) composites. This paper investigates the technical feasibility of using a low power continuous wave carbon dioxide laser for removing the top resin layer of CFRP without damaging the underlying fiber. The operating window and damaging threshold were experimentally determined. Irradiating the CFRP surface at a power of 14W, scanning speed of 880mm/sec, and a beam overlap of 25% provides an optimal thermal condition for removal of top resin layer. A finite element model was used to explain the removal mechanisms.
