See no n.g. for adhesives & epoxies, so if there's a better forum for this,
just point me to it.

I need an epoxy that is strong to the point of brittle. I want no flex; it
has to transmit vibration as close to 100% as possible.

Am I looking for a high Shore Hardness value? That's what Devcon uses in its
data sheets to specify hardness.

Is this something that I can achieve by changing the mix of the 2 parts? If
so, what do I lose if I use more hardener?

Any personal experiences with epoxies that you found to be harder than
others?

Thanks.

For spacecraft vibration testing we use Dental cement. It's extremely
non-compliant so it is good for transmitting vibration from a
structure to an accelerometer. It is brittle so we remove them by
just taping them with a hammer and breaking them off the surface. We
first put a layer of thin tape on the surface to protect the surface.
the tape does not affect the vibration response.
