Engraved aluminum honeycomb panel

Aluminum honeycomb panels are suitable for civil construction, vehicle and ship decoration, etc. They represent the application of aerospace materials in the civil construction sector. The entire manufacturing process is completed in modern factories using hot-press forming technology. Due to the high thermal conductivity between the aluminum skin and the honeycomb, the thermal expansion and contraction of the inner and outer aluminum skins are synchronized. The aluminum honeycomb skin has small holes that allow gas inside the panel to flow freely. The sliding installation buckle system prevents structural deformation during thermal expansion and contraction. The panel primarily uses high-quality 3003H24 alloy aluminum plate or 5052AH14 high-manganese alloy aluminum plate as the base material, with a panel thickness of 0.8~1.5mm fluorocarbon roll-coated plate or color-resistant baked paint. The color-resistant baked paint outperforms PVDF in terms of scratch resistance, acid rain corrosion resistance, color change resistance, and self-cleaning properties. The backplate thickness is 0.6~1.0mm, and the total thickness is 25mm.

The core material adopts a hexagonal 3003-type aluminum honeycomb core, with aluminum foil thickness of 0.04~0.06mm and side length of 5~6mm. Roll-forming technology is used to shape the front and back skins, and fully automated machinery folds the edges, ensuring the front and back skins tightly interlock at the installation edges. The entire manufacturing process is completed in modern factories using hot-press forming technology. Due to the high thermal conductivity between the aluminum skin and the honeycomb, the thermal expansion and contraction of the inner and outer aluminum skins are synchronized. The aluminum honeycomb skin has small holes that allow gas inside the panel to flow freely. The sliding installation buckle system prevents structural deformation during thermal expansion and contraction, thereby ensuring extremely high flatness. The adhesive used is a two-component polyurethane high-temperature curing glue. The panels are formed under pressure and high temperature using fully automated honeycomb panel composite production equipment, overcoming the brittleness issues of previous honeycomb panel adhesive layers. The inner layer consists of a specially designed hexagonal aluminum honeycomb, made from H19-hardness aluminum alloy, which serves as the core board adhered within the sandwich structure and bears pressure tangentially. These densely interconnected honeycombs act like numerous small I-beams, dispersing pressure from the panel direction, ensuring even force distribution, and maintaining high flatness even over large areas.

Installation is done on both sides without mechanical damage. The sliding installation buckle system allows for thermal expansion and contraction, and the anti-slip buckle at the bottom of the panel controls the direction of expansion. The 25MM hidden seam system is aesthetically pleasing and self-cleaning. The completed box-type honeycomb panel forms an integrated structure with the inner and outer plates and the honeycomb. Additionally, the hollow honeycomb significantly reduces the thermal expansion of the panel.

Due to its excellent properties such as resistance to high wind pressure, shock absorption, sound insulation, thermal insulation, flame retardancy, and high specific strength, honeycomb materials have been used in various civil fields abroad since the 1960s and have developed rapidly. In China, honeycomb technology has only recently been applied in various sectors of the civil industry. Aluminum honeycomb panel curtain walls are widely used in high-rise building exterior wall decoration due to their advantages such as light weight, high strength, and high stiffness. A honeycomb panel with a total thickness of 15mm and front and back plates of 1.0mm thickness weighs only 6Kg/㎡. A honeycomb panel with the same stiffness weighs only 1/5 of an aluminum single plate and 1/10 of a steel plate. The interconnected aluminum honeycomb core acts like countless I-beams, with the core layer distributed and fixed across the entire panel surface, making the panel more stable. Its wind pressure resistance far exceeds that of aluminum-plastic panels and aluminum single plates, and it features low deformation and excellent flatness. Even with large panel sizes, it can achieve extremely high flatness, making it a lightweight material in the construction industry.
