    摘要:

    采用准分子激光表面处理技术用于碳纤维复合材料胶接面的预处理,通过对照试验、显微镜观察研究了表面处理方式、处理后清洗方式对胶接强度和离散系数的影响。结果表明:准分子激光表面预处理技术用于处理碳纤维复合材料胶接表面能明显提高其胶接强度,与砂纸打磨处理试片的胶接强度相当,但采用准分子激光处理的试片的胶接强度离散系数相对较小。

    Abstract:

    The excimer laser surface treatment technology was applied to the pretreatment of the carbon fiber composite bonding interface. The effects of surface treatment and post-treatment cleaning methods on the bonding strength and dispersion coefficient were studied by contrast test and microscope observation. The results show that the excimer laser surface pretreatment technology can significantly improve the bonding strength of the carbon fiber composite bonding interface, and there is not much difference in the bonding strength between the sandpaper grinding test piece and the excimer laser surface pretreatment piece.However, the adhesion strength of the test piece treated with the excimer laser showed relatively smaller coefficient of variation.
