Aluminum Honeycomb Panels Manufactured
Aluminum honeycomb panels are made of a core formed of aluminium nitride or anodized aluminium honeycomb sheets, and is sandwiched between two face sheets. The core sheet has a hexagonal structure and is connected to the aluminium skin on both sides, making an I-beam-like structure that makes the panel durable and able to resist high-impact stress. It is also non-combustible and has a fire rating of FR grade A2+. The honeycomb material is lightweight and has a low density, allowing the overall panel to be extremely light. This makes it ideal for use in applications like aerospace engineering, metro coaches and theatres.
The manufacturing process for aluminum honeycomb panels is relatively simple. The raw material starts off as a block of uniform standard pre-rolled high-grade aluminium alloy coil, where it is cut into the appropriate size and thickness to suit the needs of the application. The aluminium honeycomb is then expanded and the finished panels are bonded with the outer face sheet. The finished products are then finished with a range of paint and colour coatings to match the client requirements.
These composite honeycomb panels have a very favourable strength-to-weight ratio, combining the rigidity of a solid core with the lightweight properties of aluminium. These honeycomb panels are also corrosion-resistant and have elevated temperature performance, and their mechanical properties ensure that they are strong enough for the rigorous demands of most high-specification industries. They are not only non-moisture absorbent but also resistant to mould and fungal growth, making them a suitable choice for clean rooms in which hygiene is essential.
How Are Aluminum Honeycomb Panels Manufactured?
They are also an excellent insulator against sound, as the honeycomb material prevents sound waves from passing through it and reflects them instead, absorbing the energy of the vibration. The resulting sound-proofing is highly efficient.
The growth of the global aluminum honeycomb panel market is driven by the increased production of vehicles and their parts, as well as a growing demand for environmentally-friendly materials. The market is expected to grow at a healthy CAGR over the next five years, and will be especially prominent in developing countries, due to a surging automotive industry and the rising demand for eco-friendly building materials.
There are several different types of aluminium honeycomb core available to suit a wide range of applications. The most popular is a solid aluminium honeycomb core, which offers high strength and stiffness at a very low weight. The other main type is a paper honeycomb core, which is very cost effective and has excellent insulating properties. This type is ideal for applications where a smooth finish is required and the panels will not be exposed to direct sunlight.
