Abstract (en)
The present invention provides a method for surface treatment of carbon fibers which comprises allowing an alkali metal nitrate to adhere to carbon fibers in an amount of 0.01-5% by weight based on the weight of the carbon fibers and then heat treating the carbon fibers in the air at a temperature between at least the melting point or at least the decomposition temperature of the alkali metal nitrate and lower than 500 DEG C.
