---------------------- multipart/alternative attachment 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.
