6 FAQs about [Energy storage welding of honeycomb plates]
Does welded honeycomb have a higher density than other honeycomb structures?
For fabricated welded honeycomb, this ratio is higher than that obtained for other honeycomb structures. This proposed honeycomb possesses a relatively higher density. However, the density can be reduced by increasing the size of the cells and reducing the sheet thickness.
Can friction stir welding improve the crashworthiness of aluminium honeycomb?
An innovative fabrication method based on friction stir welding is proposed to enhance the crashworthiness property of aluminium honeycomb and address the challenges with conventional fabrication methods. Moreover, a lab-scale fixture is designed to demonstrate the feasibility of the suggested method for industrial use.
Are spot welded honeycombs discontinuously bonded?
Considering that spot welded honeycombs are discontinuously bonded, it is expected that there will be a significant variation in stress and folding pattern of cell walls under flatwise compressive loading, and stress concentration will result in tearing along the spot-periphery of welded cell walls.
How much energy does a honeycomb absorb?
Designed as a lightweight crashworthy structure, specific energy absorption capacity of the honeycomb is a vital indicator of its crashworthiness. In the fabricated honeycombs, SEA is estimated to be 14.2 ± 1.3 kJ/kg, which does not change significantly with the number of cells or core height.
What is a honeycomb structure?
Honeycomb structures of interest are made up of plates or sheets of diameters varying from tens of micrometers to tens of millimeters that shape unit cell edges. Closed-cell structures make up the majority of honeycombs. To make a cellular solid, these unit cells are replicated in two dimensions.
How to improve the crashworthiness of honeycomb structures?
To improve the crashworthiness performance of honeycomb structures, various strategies have been employed, including incorporating embedded elements (such as foam, tubes, or polymer structures), using tandem configurations (connecting multiple honeycombs in series), and implementing higher-degree hierarchical honeycomb designs .
