I am working on the design of an impact attenuator for a Formula Student car.
I am interested in using aluminium honeycomb, specifically the 19.1mm cell size as it is the most cost effective, and I am in the process of testing a design using this in solidworks.
One concern I have is how the sheets and honeycomb layers will be bonded together.
I have attatched an image of the current attenuator design because it is a little bit difficult to explain.
I would like to know, along with what the best resin/adhesive to use is, what material exactly should be selected and used during the cad process.
I can see that it is of the 3003 series, however I am unsure what material out of this series specifically as they are given properties in solid form rather than treated as a honeycomb section.
All help and feedback is greatly appreciated!
I am also open to using a different material providing it is not ridiculously expensive. The budget for this project is around £500 so it is limited.

keying is the process of leaving a rough finish on the surface, in this case usually with sand paper. Keying helps adhesion.

The other issue I have is when modelling it, what should the thickness of the aluminium be set at?
I don't mean the cell size or the thickness of the aluminium honeycomb layer, I mean the thickness of the actual material.
Right now this is being modeled at 0.5 mm, however I am concerned that this is too thick, or just not accurate.
I have attached a screenshot of a creo sketch, consider the area shaded orange, this is the thickness that needs to be correctly defined.
