Abstract

This invention is related to the carbon fiber-embedded heating paper and thereof sheet heater. The alignment of the carbon fibers is controlled to give different heating characteristics to lateral and transverse directions of the said heating paper, which improves a variety of adaptabilities by using the said heating paper. The present invention is to provide the heating paper where the pulp is fabricated in the carbon fiber to have heating characteristics to lateral and transverse directions and the sheet heater comprised of the polymer coating to have electrically insulating characteristics. A variety of characteristics can be obtained from the sheet heater in case of need.
