Looking for off the shelf honeycomb plates made of paper, aluminum etc,. that can be used for impact attenuatation based on the cruchable stress of the honeycomb.

Are you just fond of honeycomb, or would a foam work?

I have some info on foams but any info will be welcomed

Paper - off the paper shelf options . . .

1. Egg crate boxes - if you need something stronger than one - stack then one inside the other - cheap and great for first experiments if you want some preliminary emperical results

2. If you want something "more rigid" consider corrugated cardboard (the kind with one outside paper surface removed). This can be rolled up (as delivered?)and cut on a table saw to whatever depth/thickness you desire.

3. Regular (two sided) corrugated cardboard (4x8 sheets?)cut into desired widths and then stacked (glued?)into blocks.

Thank you all for your responses but, my application is concerning high altitude parachute dropable heavy cargo. This has to be a crushable honeycomb with known and proven crush stress values. The info I have is for MIL-N-9884 Honeycomb Material, Cushioning, Paper referenced in MIL-STD-669B. This type of honeycomb has too high stress for my application.

Sorry, for a typo error, it should be MIL-H-9884 Honeycomb Material, Cushioning, Paper

Don’t know if they have the test values or meet the specs, but you might want to give these people a call.

You might ask for a QPL for that military
spec. In which case, it lists the accepted
manufacturers.

A foam option:

(follow links for Airex foam)

Do a search for "composite structural foam"...you will get plenty of information...

The US Navy also did some work on LasCor (not sure about the spelling). It was basically a metallic cardboard. I wasn't terribly impressed, but this may be a good application for it since metals are generally well understood for FEA purposes...
