high impact absorbing material

high impact absorbing material

high impact absorbing material

(OP)
I am looking for a material for a part of size of 500x500x6mm, that can absorb an impact force of at least 60 jules.

Any ideas?

RE: high impact absorbing material

Look into multi-layer honeycomb structures.  They absorb a lot of energy when crushed.  I take it that this is a one use requirement.  Any temp limits?

RE: high impact absorbing material

Absorb to what extent?  

A sheet of steel will "absorb" such an impact.  The impactor might be squashed flat, though.  

You need to provide more details.  Speed, weight of object, g-level, etc.

Re honeycomb

Another requirement is that the impact will not damage the metal/not crush.

Thanks for your help!

RE: high impact absorbing material

If you can't use crushing to absorb impact then it will require layered open cell polymer foam, and a lot of thickness.  You have to use a face layer that is strong enough to spread the impact and prevent penetration.
How many times do you expect this to handle the impact?
