carbon fiber (CF for short) is a new fiber material with high strength and high modulus, and its carbon content is over 95%. Microcrystalline graphite material is made by stacking organic fibers such as flaky graphite microcrystals along the axial direction of the fibers and carbonizing and graphitizing them.
although carbon fiber has the characteristics of crystals, it has a disordered layer structure (layered graphite tiny crystals are piled up), so it is not a real crystal. At present, only South Korea can produce carbon fiber electric heating film products.
technically, there is no term "carbon crystal", and the term "carbon crystal floor heating" in the media is only the propaganda of some manufacturers. The so-called carbon crystal product refers to a plate made of carbon particles as conductive materials and added with adhesive. The production of this product does not require any high-end technology and patents.
