Friction Coefficient
(OP)
Anyone know the coefficient of friction between glass and vulcanized fibre?
or glass on a similar material to fibre.
Anyone have a good reference for coefficients of friction?
Thank you.

Perhaps your suggestion was made in jest.
RE: Friction Coefficient
It is not a jest. It is a very simple experiment which we performed in class during first year engineering. The coefficient of friction between vulcanized fiber (or a similar material) and glass is likely dependent upon who manufactured the fiber and the glass, and the surface roughness of each.
And nutte, there are better ways of measuring slope than your kid's plastic protractor.

That said - it would not cost all that much to take your ideas and results to a professional lab and have them redo and/or certify the results.

Coefficient of friction for fibre on fibre is 0.16, for fibre on smooth cast iron is 0.21. Unfortunately, they don't provide figures for fibre on glass.

In any case if the friction value is critical to the design you should do analyses with upper and lower bound values, and it would be a good idea to do your own tests in addition to looking at published values to establish reasonable values for those.
