Carbon composite material incorporating carbon film, forming material and process for producing the carbon film

A process for producing a tapelike pitch-based carbon film characterized in that spinnable pitch is extruded from a nozzle having a slit into a sheet of pitch, which is then pulled by and wound on a take-up device, made infusible and carbonized, wherein gas streams having a temperature of about 200.degree. to about 400.degree. C. and having an outward component and a downward component are applied to the sheet of pitch being reduced in width by the pull in the vicinity of widthwise opposite ends thereof before the sheet fully solidifies, in directions symmetric with respect to a phantom plane extending through a central point of the slit and perpendicular to a plane in the lengthwise direction of the slit, to prepare a tapelike pitch film, which is made infusible and carbonized, and wherein the resulting carbon film has an aspect ratio of about 10 to about 1000.
