A process for producing binderless, single phase bulk carbon or graphite articles having a fibrillar microstructure comprising the steps of assembling a plurality of polymer fibers into a preselected pattern, subjecting them to a temperature and pressure sufficient to cause heat distortion flow and concomitant self-bonding of contiguous fibers and pyrolyzing the fibers in a nonoxidizing atmosphere.
