aluminum honeycomb core

タイトルまたは説明

Aluminium honeycomb produces one of the highest strength/weight ratios of any structural material. There are various configurations of the adhesive-bonding of the aluminium foil which can lead to a variety of geometric cell shapes (usually hexagonal). Properties can also be controlled by varying the foil thickness and cell size. The honeycomb is usually supplied in the unexpanded block form and is stretched out into a sheet on-site. Despite its good mechanical properties and relatively low price, aluminium honeycomb has to be used with caution in some applications, such as large marine structures, because of the potential corrosion problems in a salt-water environment. In this situation care also has to be exercised to ensure that the honeycomb does not come into direct contact with carbon skins since the conductivity can aggravate galvanic corrosion. Aluminium honeycomb also has the problem that it has no ‘mechanical memory’. On impact of a cored laminate, the honeycomb will deform irreversibly whereas the FRP skins, being resilient, will move back to their original position. This can result in an area with an unbonded skin with much reduced mechanical properties. Description: Aluminum honeycomb is a lightweight core material which offers excellent strength and corrosion resistance. Depending on requirements the honeycomb can be made from either ***3, ***5 aluminum alloy foil. Features: • Elevated use temperatures • High thermal conductivity • Flame resistant • Excellent moisture and corrosion resistance • Fungi Resistance • Low weight/High Strength Applications:Aluminum honeycomb uses include aircraft floors, tooling panels, fuel cells, shelving, panels and anywhere else a lightweight, high strength solution is required. Availability: Aluminum honeycomb is available unexpanded block slices.
