Furthermore, the thickness of the honeycomb core is 2-10mm, the thickness of the glass fiber cloth is 0.3-0.8mm, and the thickness of the rock plate is 1-5 mm.

Further, the thickness ratio among the honeycomb core, the glass fiber cloth and the rock plate is 1:0.05-0.1: 0.2-0.6.

Further, the edge of the cloth layer is flush with the side face of the honeycomb panel.

Furthermore, both sides of the honeycomb core are provided with adhesive layers and panels.

Compared with the prior art, the utility model has the beneficial effects that:

the composite board with the honeycomb structure comprises a honeycomb core, an adhesive layer and a panel which are sequentially glued, wherein the adhesive layer is a flexible cloth layer, and when the cloth layer is connected with the honeycomb core, the cloth layer is sunken towards honeycomb holes and deforms to bond the cloth layer with the wall surface of a hole frame, so that the bonding area is increased, and the bonding force between the honeycomb core and the panel is increased.
