Description

Wood-based three-dimensional hollow composite board
Technical Field
The invention relates to a composite board, in particular to a wood-based three-dimensional hollow composite board.
Background
Due to the properties of sound insulation, heat preservation and the like, the hollow composite board is more and more widely applied. However, the conventional hollow composite board is usually in a "sandwich" structure, i.e. a light foam core material is filled between the upper and lower panels. Some fiber 3D hollow fabric reinforced composite materials are arranged in the core materials and connected with the upper panel and the lower panel in order to solve the problem that the impact resistance is not ideal due to the fact that the core materials are easy to peel off from the upper panel and the lower panel and the layering defect is easy to generate.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a wood-based three-dimensional hollow composite board, which solves the problem of matching of functionality and structural strength of the traditional sandwich material with a sandwich structure.
The invention relates to a wood-based three-dimensional hollow composite board, which comprises an upper panel and a lower panel, wherein a foam layer is arranged between the upper panel and the lower panel, a 3D hollow fabric reinforced composite material layer is arranged between the upper panel and the foam layer, a 3D hollow fabric reinforced composite material layer is arranged between the lower panel and the foam layer, and bonding layers are respectively arranged between the upper panel and the 3D hollow fabric reinforced composite material layer, between the 3D hollow fabric reinforced composite material layer and the foam layer and between the lower panel and the 3D hollow fabric reinforced composite material layer.
In the invention, the upper panel and the lower panel bear tensile and compressive stress in the composite structure and can also have the functions of wear resistance and beauty; the 3D hollow fabric reinforced composite material layer is a fiber reinforced resin matrix composite material layer, is used for connecting the upper panel, the lower panel and the foam layer, is used for supporting the panel and transferring the load of the panel, simultaneously increases the section moment of inertia of the composite plate and the rigidity of the composite plate, and is hollow, so that the composite plate has higher sound insulation, heat preservation and noise reduction functions; the foam layer also provides the functions of load transfer, rigidity improvement, heat preservation, sound insulation and noise reduction; the adhesive layer makes adjacent layers mutually matched to form a whole body to conduct shearing force.
The invention creatively adds a foam layer transition layer, designs a novel multilayer composite structure of the sandwich material, separates the 3D hollow fabric reinforced composite material layer, and changes the bearing transfer surface of the 3D hollow fabric reinforced composite material layer from between an upper panel and a lower panel into between the upper panel and the lower panel and between the middle foam transition layer.
Preferably, the height of the 3D hollow fabric reinforced composite material layer is less than 1/2 of the height of the foam layer, so that the instability risk is greatly reduced; on the other hand, the upper and lower panel bearing surfaces of the traditional sandwich material are 'rigid bodies', one end of the structure bearing surface of the sandwich material is an upper panel or a lower panel, and the other end of the structure bearing surface is a soft foam layer with certain elasticity, so that the whole multilayer sandwich structure has more excellent functions of absorbing vibration, damping and resisting impact.
The upper panel and the lower panel are wood-based plates and are made of high-density recombined wood or density boards or solid wood or wood plastic or resin-based composite materials.
The foam layer is mainly one of polyurethane, polyvinyl chloride, polyethylene, polyester, phenolic aldehyde or epoxy foaming materials, and the density of the foaming materials is 20-200 Kg/m3。
The main component of the bonding layer is epoxy resin or urea resin or polyurethane.
The 3D hollow fabric reinforced composite material layer is commercially available, wherein the resin matrix is not limited to thermosetting resins such as unsaturated resin, vinyl resin, epoxy resin and the like, and can be thermoplastic matrix materials such as polypropylene, polyester, nylon and the like, the hollow fabric can be formed by weaving one or more reinforcing fibers such as glass fiber, basalt fiber, carbon fiber, aramid fiber and the like, and the structure of the hollow fabric can be 8, V, X and I type independent or interpenetrated Z-direction reinforcing structure.
The wood-based three-dimensional hollow composite board is composed of a wood-based board, an adhesive layer, a 3D hollow fabric reinforced composite material layer, a foam layer, an adhesive layer and a wood-based board from top to bottom. Generally, the above structure is a symmetrical structure to avoid the deformation of the plate, but it can be designed into an asymmetrical structure according to the requirement.
The invention has the advantages that: the wood-based three-dimensional hollow composite board provided by the invention has better structural strength, rigidity, heat preservation and sound insulation than the traditional sandwich foam board. The wood-based three-dimensional hollow composite board can be made of foam materials according to actual requirements, the 3D hollow fabric reinforced composite material layer is variable in structure and strong in designability, can be widely used as walls, door plates, floors and the like, is good in product universality, can be designed randomly in appearance, is attractive and elegant, is simple in production method and low in cost, and has good market value.
