<p>The present invention relates to a magnesium alloy honeycomb board and a production process thereof. The magnesium alloy honeycomb board is formed through the glue-jointing of an upper panel, a lower panel and a honeycomb core structure, and is characterized in that : both the upper and lower panels are made of magnesium alloy sheets with a thickness of 0.6 to 3.5mm, and the honeycomb core structure is made of magnesium alloy foil with a thickness of 0.08 to 0.25mm; the thickness of the honeycomb board is within 8 to 45mm, the thickness of the honeycomb core structure is within 6 to 38mm, the height of the hexagonal honeycomb aperture is within 5 to 15mm, and the fillet radius is within 0.4 to 1.2mm. The honeycomb core structure is a regularly-hexagonal one formed through the rolling, cutting, plastic bending, accurate forming and positioned bonding of high-strength magnesium alloy, and is then glue-jointed with the high-strength magnesium alloy panels to form the magnesium alloy honeycomb board with high strength and ultra-light weight through pressurizing solidification. Being capable of realizing the weight reducing effect, the magnesium alloy honeycomb board not only can be used as components like wallboard, floor, partition board, etc. in such transportation equipment as spacecrafts, aircrafts, light-weight rapid trains, urban railway trains, etc., but also can be applied in other structures as panel or partition board.</p> |
