 　What are the characteristics of honeycomb aluminum plate?

Honeycomb aluminum plate features: light weight, low density:Honeycomb aluminum plateThe core layer is a typical porous structure, and the continuous polygonal cells are regularly arranged, so the cross-sectional area of the solid part of the honeycomb plate is very small, so its density is also very small compared to other sandwich materials.

Since the density of honeycomb panels is much smaller than that of ordinary plates such as laminates and steel plates, its quality is also the lightest when the volume is the same. The quality of honeycomb aluminum plate is only 9% of the same volume of FRP laminated plate, 11% of the same volume of steel plate, and 23% of the same volume of aluminum alloy plate.

This allows the honeycomb aluminum sheet to save a lot of energy when used in aircraft. The low density and light weight make the honeycomb panel well meet the requirements of lightweight, energy saving and environmental protection for materials used in aerospace engineering aircraft and transportation tools.

The characteristics of honeycomb aluminum plate: high specific strength and good rigidity: from a mechanical point of view, the structure of honeycomb aluminum plate is similar to that of many I-beams connected to each other, and the panel is similar to the flange of I-beams, which mainly bears the role of in-plane load, while the honeycomb core is similar to the web of I-beams, and its main function is to bear shear stress and connect and support upper and lower panel pieces.

But the honeycomb core is different from the web of the I-beam,Stone Honeycomb PanelNot thin reinforcement but dense reinforcement, the core layer distribution is fixed in the entire plate surface, and the height of the core layer is much larger than the thickness of the panel, which makes the section inertia moment also doubled, while improving the overall stiffness of the overall stability is also greatly increased.

Factors Affecting Peel Strength of Honeycomb Aluminum Plate: Effect of Adhesive on Peel Strength of Honeycomb Aluminum Plate

　　arc honeycomb panelThe honeycomb aluminum plate produced by polyurethane and epoxy resin room temperature curing adhesive has low bonding strength. The 180 peel strength measured for honeycomb aluminum plate with honeycomb core side length of 4mm, panel thickness of 1mm and total thickness of 10mm is about 4N/mm. The adhesion and weather resistance of the honeycomb aluminum plate are poor, and the adhesion performance is greatly reduced after 1 year of use. The honeycomb aluminum plate produced by this process is not suitable for outdoor use, but can be used for indoor decorative partitions.
