Bonding Aluminium Honeycomb (19.1mm cell size ) to sheet Aluminium.

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.

Ok perfect, I shall use 50 microns in my modelling from now on.

Your description of the cell construction makes sense, I shall ensure that the top and bottom faces (assuming a regular hexagon) are 100 microns in my modelling.

Thank you so much for all your feedback and support, you have been very helpful.
