Abstract:

A large number of glassy carbon samples was produced by controlled pyrolysis of furfural alcohol resins, examined for structural differences, and evaluated for physical and mechanical properties. It is concluded that glassy carbon is a family of materials whose properties can be varied over a significant range, depending both on the small scale 2-50A carbon structure, and the amount and distribution of porosity which may be present in substantial amounts. The combination of availability, chemical stability, low density and high strength make glassy carbons look promising for mechanical applications, particularly at very high temperatures.
