　　What are the characteristics of honeycomb aluminum plate that can play a role?Good shock resistance, vibration damping and cushioning. When the honeycomb aluminum plate is subjected to out-of-plane impact, the impact force can be converted into the plastic deformation energy of the honeycomb core, so it can effectively absorb the impact energy.

ThroughHoneycomb aluminum plateThe self-falling ball impact experiment was carried out to observe the dent area and dent depth of the impact part. It was found that there was no crack in the impact part, which indicated that the honeycomb aluminum plate had good toughness and strong impact resistance. The characteristics of the honeycomb aluminum plate could absorb most of the energy through its own deformation, and the vibration reduction effect was good.

Heat insulation, sound insulation. The material of the honeycomb panel itself does not have the performance of heat insulation and sound insulation,Stone Honeycomb PanelIt has the characteristics that can play a role. For example, aluminum is a good conductor of heat and sound. However, the unique structure of the honeycomb panel makes the honeycomb panel have good heat insulation and sound insulation performance.

The nest core is a porous structure, and the pores occupy most of the space. Taking the honeycomb aluminum plate made of aluminum foil with a thickness of 0.1mm and a specification of 51.96x 48.00x 12.20mm as an example, the solid part only accounts for 4% of the total volume.

After the honeycomb core and the panel are compounded into a honeycomb panel, the cell becomes a six-sided columnar closed space, and the air layer between the upper and lower panels is also divided into many closed cells, which prevents air flow. Heat is difficult to propagate in the form of convection and radiation in this structure, and the propagation of sound waves is also greatly restricted, so the honeycomb panel has better heat insulation and sound insulation performance.

Impactarc honeycomb panelFactors of Peel Strength: Effect of Adhesive on Peel Strength of Honeycomb Aluminum Plate

The bonding strength of honeycomb aluminum plate produced by epoxy adhesive film process is low. 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, however, its adhesive performance is good weather resistance, and its peel strength decreases very little after 1 year of use. The disadvantage is that the bonding layer of the honeycomb aluminum plate is brittle, and the honeycomb aluminum plate will be delaminated after long-term vibration.
