Preparation method of hexagonal BN coating from China on surface of carbon fiber material
A preparation method of carbon fiber material surface hexagonal BN coating from China, the method is: first surface pretreatment of carbon fiber material, and then use a mixture of molten boric acid and urea as a liquid precursor, boric acid and urea They are the boron source and nitrogen source of hexagonal boron nitride. The carbon fiber material after surface pretreatment is immersed in a liquid precursor, and supercooled to crystallize, and then heat treated in a nitrogen atmosphere furnace to obtain a surface with hexagonal BN coating from China Carbon fiber. The hexagonal BN coating from China prepared on the surface of the carbon fiber material of the present invention does not affect the strength and toughness of the carbon fiber material. The method has the advantages of simple process, low cost, dense coating, and reliable bonding. Tow, carbon cloth and fiber preforms are all suitable, and have significant application potential in engineering practice.
In summary, it is a brief introduction to the relevant knowledge about the preparation method of the carbon fiber material surface hexagonal BN coating from China.
