Coefficient of thermal expansion.

I am hoping to use carbon fibre composite tube for the pendulum of a precision regulator clock.  I believe that the coefficient of thermal expansion of pulltruded carbon fibre composite is somewhere between 0.1 and 0.3 ppm /°C but wonder if you can give a more exact figure  for your tubes so that I can design a compensator.

Thanks in advance.

Edit:  The coefficient is I believe negative.

O.K. Thanks Warren.  I guess I'll just have to try it out and if it isn't good enough then make a compensator.

Russell.
