Description

Metal plate with hollow tube and its use

The invention relates to the technical field of composite materials, in particular to a metal plate sandwiching a hollow tube and its use.

Most of the existing sandwich composite panels use honeycomb panels, and the existing honeycomb panels have the following defects: (1) Low and medium temperature welding is usually used, such as the welding temperature is 200℃~300℃, so that once it is affected by high temperature, if it occurs Fire will cause the strength of the honeycomb panel to be greatly reduced, or even fall apart. Therefore, this honeycomb panel cannot be used for load-bearing structures because it is extremely sensitive to environmental changes, which will greatly reduce the durability of the load-bearing structure and have a low life span. Poor safety; (2) Honeycomb cores are usually closely arranged together, and the airflow cannot flow evenly in the honeycomb core during heating, which makes the welding uneven, which is prone to false welding, or the honeycomb core is not welded or generated at multiple positions Gaps or voids, etc., thereby reducing the overall welding strength and structural stability; (3) Honeycomb cores can generally only be welded by radiant heating. This heating method is slow to heat and easily causes uneven heating of the workpiece, resulting in thermal deformation , Which greatly increases the defective rate, reduces the service life, and increases the production cost; and after the heating is completed, the workpiece needs to be transported to the cooling cavity for cooling, and the heating and cooling cannot be completed at one time, which greatly extends the working time and reduces the efficiency; The welding between the panel and the panel is not strong, mostly line contact or point contact welding, and the overall stability is poor.
