Hafnium diboride (HfB2) is a new type of ceramic material with high melting point, high thermal conductivity, oxidation resistance and other high-temperature comprehensive properties. It is mainly used in ultra-high temperature ceramics, high-speed aircraft nose cones, aviation, aerospace and other fields. Hafnium diboride (HfB2) is mainly used as a modifier for carbon-carbon and carbon-ceramic composite functional materials: Hafnium diboride (HfB2) modified carbon fiber can greatly improve the strength of carbon fiber, increase fatigue resistance and wear resistance And high temperature resistance, the modification effect is very obvious, and all indexes are greatly improved.
