Problems solved by technology

[0002] Generally speaking, carbon fiber composite materials are a single composite of organic bonding materials (such as epoxy resin) and carbon fibers, without a ceramic matrix, so they do not have ceramic properties and are very expensive.
[0003] Carbon fiber composite materials are not uncommon at home and abroad. The general carbon fiber composite materials are structural materials composed of carbon fiber and organic resin, such as carbon fiber reinforced epoxy resin composite materials. The highest, quite advantageous, has been applied in domestic aviation and automobiles, etc., but there is no high-temperature resistant, high-hardness, light-duty and low-cost carbon fiber composite material. The carbon fiber composite material of silicone modified epoxy resin or polyimide resin is resistant The highest temperature is only 400-500 degrees, and the cost is very high, which limits the scope of promotion and use
However, low-cost, high-hardness ceramic carbon fiber composite materials that are resistant to more than 1000 degrees, especially those that can withstand high temperatures up to 2000 degrees, have not been reported at home and abroad.
