Honeycomb sandwiched panel is widely used because of its high strength, good impact performance,vibration damping and its excellent designability, such as airplane,helicopter, satellite, boats and more. Now, the most popular honeycombs are made of aluminium and aramid material, other materials are still in testing in the lab, like steel honeycomb, though it has a lower cost and high strength, but it is not superior on weight.
Aluminium honeycomb is with regular hexagonal structure, composite with high quality aluminium foil by glue and expanded to its demanded sizes. Different foil thickness, different cell size and thickness will decide the core performance. It can be compounded with other faced materials to kinds of sandwich structure panels, which is competitive in price and mechanical properties.
Aluminium honeycomb is lighter compared with other materials as its lower density, its weight is only 1/5 wood, 1/6 glass, 1/7 solid aluminium at the same thickness, same area, which greatly reducing the building self loading and cost. The cell structure contains great air, which has good effect on sound insulation(the air sound reduction index is up to 30dB), heat protection(the thermal resistance is 0.02㎡·K/W), water proof. And because of its full metal structure, the face and core are noncombustible, no harmful gases is released, the fire proof can be B1 class. It is also advanced at weight-strength ratio, not easy deformation, easy fabrication and installation, cutting and bending. Aluminium surface can be coated PVDF with any kinds of color like RAL series, guarantees no obvious color fade within 30 years. Aluminium honeycomb panel has a good flat surface, while is 1/8 glass weight. For example, 22mm panel with standard size, can load 700Kgs or more. In conclusion, aluminium honeycomb panel is the first choice as a lighter building material, and along with its quality to perform as an acoustic and thermal insulation, is green, environmental and energy-saving material.
