By built up do you mean a sort of lamination? This may sound silly but
what about plastics? They seem to be able to do just about anything with
them and I doubt there would be any unwanted resonances there. I've even
heard of plastics being used in brake pads for automobiles. Ceramics
would be cool but too expensive. Seems that many different things could
be used if one put their mind to it. I think more of the suitablilty
would depend on the engineering of the final product rather than the
material.<br><br>
