▎ 摘　　要

NOVELTY - Hollow multilayer resin-based composite material comprises a single-layer composite material flat plate and a single-layer composite material corrugated plate stacked layer by layer. The upper surface layer and the lower surface layer of the composite material are both single-layer composite material flat plates. Both the single-layer composite material flat plate and the single-layer composite material corrugated plate are composed of at least three layers comprising at least two layers of thermoplastic composite material prepreg and a carbon nanotube/graphene conductive film located between the two layers of thermoplastic composite material prepreg. USE - The hollow multilayer resin-based composite material is used in fields of aerospace, automotive electronics, wind power generation, energy and chemical industry, carbon fiber, glass fiber and aramid fiber. ADVANTAGE - The method enables preparing series single-layer composite material flat plate, corrugated plate and multi-layer hollow composite material plate, so that the preparation method is simple, the product quality is lighter, the strength is higher, and the material has good practical application value. The method ensures that the carbon nano tube/graphene conductive film is ultra-light, ultra-thin characteristics not only has small influence to the volume and weight of the composite material, the natural has a porous structure, can be perfectly fused with the resin base material, nano-structure also can enhance the material, at the same time, increasing the material's conductive characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the composite material, comprising stacking a single-layer composite material flat plate and a single-layer composite material corrugated plate layer by layer, heating the carbon nanotube/graphene conductive film with electricity, applying pressure to the overall structure to promote the partial melting of the resin material at the joint between the corrugated plate and the flat plate, and solidifying the connection.
