PURPOSE:To obtain the titled material used for composite materials and having excellent affinity for matrices by treating the surface of carbon of a carbonaceous material consisting of hexagonal carbon network with gaseous fluorine. CONSTITUTION:The surface of carbon of a carbonaceous material consisting of hexagonal carbon network such as graphite, carbon black, carbon fiber, etc. is treated at 1-500mm.Hg partial pressure of fluorine for 0.5min-1hr by placing the carbon into a cylindrical reactor equipped with a mesh plate and an agitator, etc. which is arranged in a thermostat at -80-50 deg.C, keeping the inside of the reactor under vacuum, and introducing gaseous fluorine, which is diluted with an inert gas such as N2 and Ar and the gas such as air and O2 at need, from the lower part of the mesh plate. The titled material used for composite materials is obtained in this way. |
