Description

Composite plate structure and its manufacturing method

technical field

The invention relates to a composite board structure and a manufacturing method thereof, in particular to a composite board structure with a hole structure made from recycled raw materials and a manufacturing method thereof.

Background technique

In the current prior art, the composite plate structure mainly composed of hole structure is mostly made of aluminum honeycomb plate as the main body of the composite plate structure, and the skin of metal raw materials such as aluminum and steel is pasted on the honeycomb plate. In this way, the assembly and combination of the composite plate structure is completed.

However, this kind of composite board structure is made of metal raw materials, so the overall weight will be heavier than the composite board structure generally made of other materials, and the purpose of light weight cannot be achieved. Moreover, when metal raw materials are used as materials, their cost is relatively high compared with other raw materials, thus increasing the production cost.

In addition, in addition to metal materials, iron is also the most commonly used material for manufacturing composite plate structures. The iron plate is prone to rust when exposed to the air for a long time, which will damage the external appearance and affect the overall firmness. Therefore, It is necessary to use other methods to prevent rust, which increases the cost and time of the manufacturing process. For example, a layer of stainless steel is added by melting on the surface of the composite plate structure. This kind of manufacturing method not only still has many problems, but also relatively increases the manufacturing cost.

In addition, there are also composite panel structures made of wood or plastic as the main body. Not only can the composite panel structure fail to produce lightweight effects, but the composite panel structure made of wood may also encounter problems such as moisture and insects. The structure of the composite board is damaged, and although the composite board structure made of plastic is lighter than the composite board structure made of wood, it cannot achieve the effect of environmental protection in terms of the environment.

In addition to the disadvantages of the materials used in the above-mentioned composite plate structure, there are also designs in which holes are provided in the composite plate structure currently used. However, in current structures of this type, the size of the holes of each plate and the gaps between the holes are the same, resulting in poor toughness and strength of this type of structure, so it cannot better achieve the effects of light weight and structural strengthening.

Therefore, in terms of demand, providing a lightweight, low-cost, structurally strong and recyclable composite panel structure has become an urgent issue in market applications.

In the composite plate structure, the hole diameters of these plates gradually decrease or gradually increase from the center of the composite plate structure toward the upper surface layer and the lower surface layer.

In one embodiment, the manufacturing method of the composite plate structure of the present invention may further include a step of covering the upper surface layer, the lower surface layer or a combination thereof of the composite plate structure with clips.

Preferably, the composite plate structure has a plurality of voids in the longitudinal section, wherein any adjacent voids may have an I-beam (IBEAM) structure or an X-shaped truss (X Struss) structure. The voids of the composite plate structure can be spherical, honeycomb or quadrilateral.
