Impact Energy Absorber Aluminum Honeycomb Core for Vehicle Industry
Impact Energy Absorber Aluminum Honeycomb Core for Vehicle Industry is a specially developed aluminum honeycomb core product for the impact energy absorber for the sporting or vehicle industry. There is a sceintific research and test showed: velocity sensitivity of aluminum honeycomb under high-speed axial impact in a velocity range from 20 to 80 m/s. Series experiments were carried out with the help of self-developed high-speed impact system. Afterwards, corresponding numerical simulation works as well as some parametric studies were conducted. The resultant comparison told out that the plateau stress increases markedly when impact below 30 m/s, but slowly when impact at a velocity various from 30 to 80 m/s. Before the parametric studies, inertial effect in various impact masses was investigated. Comparison between parametric results showed that the promotion on Specific Load and energy-absorbing capability increases with the impact velocity for various honeycombs. Density also has a great influence on Specific Load. The higher honeycomb density is, the greater amplitude performs. The energy absorption diagram for honeycomb with different geometric configurations reveals the relationship between dynamic plane stress and energy per unit volume, and also proves the promotion with increasing of impact velocity.
Hexavalent chromium is remarkably versatile and exhibits many desirable and essential characteristics through numerous metal treatment processes such as zinc electroplating. After its initial stage of dissolution, Hexavalent chromium then enters into a thick trivalent chromium layer that controls color, thickness and a “self-healing” property. Because of the “self-healing” property, soluble hexavalent chromium compounds will re-chromate any exposed areas when damaged. Finally, adsorption into the topcoat of the hexavalent chromate completes the process.
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.
