Abstract
The present invention relates to a surface modification of carbon fibers, and more particularly to, such a method of modifying the surface of carbon fibers by irradiating an electromagnetic wave to the carbon fibers. When an electromagnetic wave of a high frequency is irradiated to the carbon fibers, the carbon fibers are modified. The modified carbon fibers have an increased surface roughness. In case of manufacturing a composite material by mixing the carbon fibers with a matrix, the modified carbon fibers are relatively greatly improved in physical property as compared to the original carbon fibers prior to the modification.
