Special Treated Aluminum Honeycomb Core for Aircraft Flooring
Special Treated Aluminum Honeycomb Core for Aircraft Flooring is made of corrosion resistant treated aluminum foil bonded by special purpose adhesive especially used for the aircraft flooring with extreme high strength and modulus. The performance of the aluminum honeycomb core is
determined by the properties of aluminum foil, special purpose chemical adhesive and the size and configuration of the core.
Trivalent chromium passivation is used for enhancing corrosion resistance of honeycomb core. In the passivating process, the amount of dissolved metal ions (for example zinc and iron) in the passivation solution increases the longer the solution is used. This results in a reduced corrosion resistance at elevated temperatures. Adding a top coat after this process improves the corrosion resistance but has an increased cost. To combat this, we strove to clarify the mechanism of decreased corrosion resistance and to develop a trivalent chromium passivation with a higher corrosion resistance at elevated temperatures.
Process
General process of an aluminum honeycomb core initiated with an aluminum foil roll and surely the foil is specially treated.
The adhesive tapes are printed to the foil surface with the intervals and width pre-determined by the cell size and strength requirement.
The foil paper is cut into required size to be piled up on the stacking table with equipment and man supervision on the adhesive tape positioning.
These stacked loose blocks should be pressed in a heated press to cure the adhesive so that the sheets of foil are bonded together to hardened block.
The aluminum honeycomb block can be cut into slices with the height of the slices tailored to customized requirements.
Finally, no matter it is done in supplier’s plant or at client’s workshop, the honeycomb should be expanded before forming aluminum honeycomb panel.
The following materials are for forming honeycomb cores:
1. Aluminum foil
Regularly, 3003H19/5052H18 aluminum alloy foils after strict surface treatment are used for producing aluminum honeycomb core.
2. Special Purpose Chemical Adhesive
Modified epoxy glue for high temperature cure process can provide not only sufficient bonding strength, but also environmental resistance and high or low temperature resistant properties. The joint strength of aluminum honeycomb core is the keypoint of evaluating the core’s performance. The minimum requirement should be more than 2.0N/mm.
