Abstract:

A carbon film from polyacrylonitrile is desired for use as a sheet-type reinforcing agent, e.g., in aircraft components such as drive shafts or spoilers where its planar isotropic properties will strengthen cut-out and joint areas. The report describes the authors research on the production of carbon fibers from polyacrylonitrile, the most effective precursor. Knowing the chemistry will allow a rational modification of the process to permit extension of the method to polyacrylonitrile in film form, the most promising precursor for sheet carbon.
