Hello,
For an experimental set-up i want to set a hot metal plate in vibrations.
temperature: ~450 °C mass of plate: 0.5 kg frequency: 0-1000 Hz max. acceration of mass: 150 m/s²
I'm searching for a material for isolating this hot plate from the vibration-excitation by a commercial shaker.
requirements:
1) low thermal conductivity (for isolating)
2) resitence to compression AND torque
3) fatigue strength
4) stiff / high bulk modulus: otherwise the material would act as a spring and wouldn'd transfer the vibrating motion.
5) easy shaping with lathe or milling machine possible
In my opinion polymers like teflon won't be stiff enough to transfer the vibration. I also thought about ceramics but I doupt they can resist vibraitonal stress.
I'm thankfull for your suggestions - best with sorce where i can buy this material in low quantities.
Thanks in advance,
Bernd
