Description

technical field [0001] The invention relates to a papermaking method, in particular to a meta-aramid fibrid fiber / carbon fiber composite electric heating and high temperature resistant carbon fiber paper and a preparation method thereof. Background technique [0002] Carbon fiber is made of raw material fibers with a high carbon content (usually above 90%), placed in an inert gas, subjected to thermally stable oxidation at 200-300°C, carbonization and graphitization at 1000-2000°C. Carbon fiber has high temperature resistance, abrasion resistance, electrical conductivity, heat conduction and corrosion resistance, etc. It has significant anisotropy in shape, is soft, can be processed into various fabrics, has a small specific gravity, and exhibits high strength along the fiber axis. [0003] Electric heating carbon fiber paper can be used for heating in public bathrooms, hot yoga, sauna rooms, and massage rooms. Moreover, because of its safety, high efficiency, easy control,...
