NOVELTY - The utility model relates to the technical field of composite board, especially claims a high-hardness composite plate. in the present market hardness of the composite board is not high, in the actual installation and use process, the composite plate surface is easy to be scratched. The utility model is orderly provided with a fabric layer on the upper lower end of the symmetrical plastic plate, an adhesive layer, a metal plate and a graphite, metal plate bonded with the fabric layer, a plastic plate by an adhesive layer; the metal plate is galvanized carbon steel plate, the plastic plate is bubble plastic board. graphene layer is three-layer structure, the outer two layers is graphene, the middle layer is carbon nanotube fabric layer is geotextile, so that the three-layer structure of graphene layer is capable of providing relatively high surface hardness, the metal plate provides rigid support, an adhesive layer and a fabric layer that the metal plate and the plastic plate is adhered, plastic board can greatly reduce the weight of the composite board, which effectively improves the surface hardness and rigidity of the composite plate and reduce the weight. The utility model is mainly used for composite board.
