Background
Along with the popularization of outdoor sports and the increase of participated people, the market has an increasing demand on the lightweight of outdoor equipment. The existing indoor table top plate is mostly made of solid wood or solid wood composite and other solid materials, is heavier in weight, inconvenient to transport and waterproof. The outdoor table is light, convenient to transport and good in weather resistance.
At present, composite materials with a sandwich structure are mostly applied to the fields of aerospace, high-speed rail carriages or wind power blades and the like. In the field of panels, there are also some composite panels of "sandwich" structure. For example, patents CN201220072327.6, CN110281603A, etc. disclose composite sheets containing an aluminum honeycomb sandwich structure. Facilities such as the existing outdoor folding table are large in mass, and the plate adopting the aluminum honeycomb sandwich can effectively reduce the weight. But aluminum honeycomb table cannot use flat edge seals as indoor table. The reason is that the tangent plane of the vertical wall of the aluminum honeycomb core can be in contact with the edge sealing strip in a smaller area, and the aluminum honeycomb core cannot be effectively attached. Therefore, the aluminum honeycomb sandwich table plate can only be sealed by U-shaped aluminum edges, is not light and handy, and reduces the attractiveness and weather resistance of the table.
