Overview:
Aluminum honeycomb panels are manufactured by bonding aluminum sheets and an aluminum honeycomb core together using hot-melt adhesive through hot pressing technology. The high thermal conductivity between the aluminum skins and the honeycomb core ensures synchronized thermal expansion and contraction. Some honeycomb foils are perforated, allowing gases to flow freely within the panel.
Core Structural Layers:
Face Aluminum Sheet/Plate
Base aluminum Sheet/Plate
These are further enhanced with a surface texture layer (color coating) on the face panel and a double adhesive layer, creating a six-layer sandwich design.
Key Advantages:
High Strength: Offers exceptional structural integrity.
Lightweight: Weighs only 1/5th of solid aluminum panels and 1/10th of steel panels with the same rigidity.
Excellent Insulation: Provides sound and thermal insulation.
Impact Resistance: Absorbs shocks effectively.
Fatigue Resistance: Durable under cyclic loads.
Weather and Fire Resistance: Performs well under harsh conditions and is flame retardant.
Waterproof and Moisture-Proof: Suitable for various environments.
Recyclable: Environmentally friendly.
Comparative Weight:
Honeycomb core panels weigh only 1/5th of wood panels, 1/6th of glass, and 1/7th of aluminum of the same thickness and area.
Exceptional flatness and resistance to deformation.
Can be easily cut and bent as needed.
Applications:
Exterior Wall Cladding: Ideal for building facades.
Interior Decoration: Enhances architectural interiors.
Roofing Materials: Provides lightweight, durable roofing solutions.
Shipbuilding: Suitable for marine construction.
Aerospace: Used in aircraft manufacturing for lightweight and strong components.
Interior Partitions & Display Stands: Perfect for commercial and retail environments.
Commercial Vehicles: Applied in the bodies of transport and freight trucks.
Public Transport: Used in the interior of buses, trains, subways, and other rail vehicles.
Manufacturing Process:
Surface Preparation: Aluminum foil is passivated and coated with node adhesive (epoxy-modified high-temperature curing adhesive).
Honeycomb Core Formation: The aluminum foil is cut to size, stacked (with the number of layers depending on the desired honeycomb core length), fused at high temperatures, cut into blocks (based on the desired honeycomb core height), and stretched into hexagonal honeycombs.
Panel Assembly: Adhesive is applied to the inner side of the base plate, the honeycomb core is placed on top, positioned correctly, and then the face panel, also coated with adhesive, is applied over the core.
Curing and Finishing: The assembly is cured under hydraulic pressure, cooled, and then cut to the desired dimensions.
