Embodiment Construction

[0016] A wood-based three-dimensional hollow composite board, comprising an upper panel 1 and a lower panel 5, a foam layer 3 is arranged between the upper panel 1 and the lower panel 5, and a 3D hollow fabric reinforced composite material is arranged between the upper panel 1 and the foam layer 3 Layer 2, 3D hollow fabric reinforced composite material layer 2 is arranged between lower panel 5 and foam layer 3, between upper panel 1 and 3D hollow fabric reinforced composite material layer 2, 3D hollow fabric reinforced composite material layer 2 and foam layer 3 Adhesive layers 4 are provided between the lower panel 5 and the 3D hollow fabric reinforced composite material layer 2 .

[0017] The height of the 3D hollow fabric reinforced composite material layer 2 is less than 1 / 2 of the height of the foam layer 3 .

[0018] Both the upper panel 1 and the lower panel 5 are made of high-density recombined wood or density board or solid wood or wood-plastic or resin-based composit...

Abstract

The invention relates to a composite plate and in particular to a wood-based three-dimensional hollow composite plate which comprises an upper surface plate and a lower surface plate, wherein a foamed layer is arranged between the upper surface plate and the lower surface plate; a 3D hollow fabric reinforced composite material layer is arranged between the upper surface plate and the foamed layer; another 3D hollow fabric reinforced composite material layer is arranged between the lower surface plate and the foamed layer; and adhesive layers are arranged between the upper surface plate and the 3D hollow fabric reinforced composite material layer, between the 3D hollow fabric reinforced composite material layer and the foamed layer and between the lower surface plate and the 3D hollow fabric reinforced composite material layer. The structural strength, the rigidity, the heat preservation and the sound insulation of the wood-based three-dimensional hollow composite plate provided by the invention are superior to those of a conventional 'sandwiched' foamed plate, the plate can be widely used as walls, door plates and floors, and the products are relatively good in universality, random in appearance shape design, good in attractiveness, simple in production method, relatively low in cost and good in market value.

Description

technical field [0001] The invention relates to a composite board, in particular to a wood-based three-dimensional hollow composite board. Background technique [0002] Due to its sound insulation, heat preservation and other properties, hollow composite panels have been more and more widely used. However, the current traditional hollow composite panels are usually "sandwich" structures, that is, the upper and lower panels are compositely filled with lightweight foam core materials. In order to solve the problem of unsatisfactory impact resistance caused by the easy peeling of the core material and the upper and lower panels, which are prone to delamination defects, fiber 3D hollow fabric-reinforced composite materials are installed in the core material and fiber 3D hollow fabric-reinforced composite materials Connect the upper and lower panels. However, if the functional requirements of the product such as sound insulation and heat preservation are improved, the thickness ...
