Effects of filler and ethanol on mechanical properties of glass-like carbon

The effects of filler and ethanol on the mechanical properties of glass-like carbon were studied. The specific gravities of glass-like carbons with the filler were higher than those of alcohol added glass-like carbons due to the formation of pores and bubbles as the alcohol was vaporized in the curing and polymerization stages. The ethanol added glass-like carbon samples also had lower bending strength than the filler added glass-like carbon samples after carbonization; a contrary result was observed after heat treatment at 2600°C. This was due to the pores that were made with ethanol which plays the role of pore former during carbonization. The fabricated glass-like carbons are quite brittle material. The shore hardness of the glass-like carbon was observed not to be affected by the addition of filler or ethanol, but increased a lot after carbonization.
