Abstract 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.
