铝蜂窝夹芯带铜网复合材料壁板胶接技术研究

Research on Bonding Technology of Aluminum Honeycomb Sandwich Panel Covered With Copper Wire Netting

针对铝蜂窝夹芯带铜网复合材料壁板胶结过程中遇到的实际问题,主要通过金属与复合材料的混杂成型工艺、蜂窝芯收缩变形控制技术、选择合适的胶粘剂、胶结质量验证等几个方面进行了研究。最终通过可操作性、消除铜网与预浸料织物热膨胀系数不同所带来的影响、防止蜂窝芯收缩工艺、选择合适的胶膜及固化参数的确定4个方面对铝蜂窝夹芯带铜网复合材料壁板胶接技术进行研究,并通过随炉试板的测试和无损检测技术验证了该工艺方法的可行性。

This paper focused on practical problems in manufacturing processes of aluminum honeycomb sandwich panel covered with copper wire netting.Improving folding process of copper wire netting,choosing suitable prepreg,adjusting heating rate,decreasing the diameter of copper wire netting and ameliorating folding means were used to reduce the impact on thermal expansion and to polish up bonding performance of copper netting and prepreg.Meanwhile,choosing suitable coating films and curing molding process of aluminum honeycomb sandwich panel was used in dry glass fabric to clasp layers and improve contraction in marginal areas of aluminum honeycomb sandwich.The practicability of the improvements was confirmed by the test of procession control panel and non-destructive test technology,which could give a reference for the manufacturing processes of aluminium honeycomb sandwich panel covered with copper wire netting.
