The mechanical properties of aluminum honeycomb panel are very outstanding, mainly reflected in the following aspects:
First, aluminum honeycomb panel is light and high-strength. Because high-strength aluminum foil is used as the base material and a honeycomb structure is formed through a special process, the aluminum honeycomb panel greatly reduces the weight while ensuring strength. This light and high-strength feature makes aluminum honeycomb panel widely used in aerospace, transportation and other fields.
Secondly, aluminum honeycomb panel has excellent rigidity. Its honeycomb structure provides good support for the board, making the overall structure more stable and not easy to deform. This good rigidity allows aluminum honeycomb panel to maintain long-term flatness and stability in the fields of building curtain walls, partitions, etc.
Furthermore, aluminum honeycomb panel has good bending stiffness. Experimental data show that the bending stiffness of honeycomb aluminum panels of the same quality is about five times that of aluminum alloy. This means that under the same bending moment, aluminum honeycomb panel can more effectively resist deformation and maintain structural integrity.
In addition, the aluminum honeycomb panel also has a certain toughness. When subjected to out-of-plane impact, it can convert the impact force into the plastic deformation energy of the honeycomb core, thereby effectively absorbing the impact energy and protecting the internal structure from damage. This good toughness gives the aluminum honeycomb panel a certain advantage in safety protection.
In terms of tensile strength, the honeycomb aluminum panel can generally reach 100-200MPa, and the specific value depends on factors such as the thickness and shape of the aluminum core board and the thickness and quality of the two thin aluminum plates. This allows the aluminum honeycomb panel to maintain structural integrity when subjected to tension and is not easy to break.
At the same time, the aluminum honeycomb panel also has a good elastic modulus. Its elastic modulus is usually between 70-80 GPa, and the specific value is affected by factors such as panel thickness, honeycomb aperture, number of layers and material. This allows the aluminum honeycomb panel to maintain a certain deformation capacity when subjected to force, while quickly returning to its original state.
The mechanical properties of aluminum honeycomb panel are excellent, with the characteristics of light weight, high strength, good rigidity, high bending stiffness, good toughness, high tensile strength and moderate elastic modulus.
