Abstract
The object of the present invention is to provide a process for manufacturing a product of glassy carbon, having endurance strength to fatigue at elevated temperature, and to thermal fatigue. After curing the material resin in a mold, the cured resin is baked to obtain a glassy carbon piece. The piece is then machined into a predetermined shape. Subsequently, the surface of the piece resulted after machining, is impregnated with the resin. Further, the resin-impregnated piece is baked so as to transform the impregnated resin into glassy carbon.
