→Research on high temperature creep characteristics of metal materials
In industries such as petrochemical, metallurgy, and machinery, a large number of metal components serve under conditions of high temperature, high pressure, and strong corrosive media. Once these load-bearing components are accidentally damaged, it will lead to catastrophic consequences and huge economic losses.

→Research on mechanical and high temperature properties of C/SiC ceramic matrix composites
SiC ceramics have the characteristics of high strength, low density, excellent thermal shock resistance and oxidation resistance. However, its disadvantage is high brittleness, which seriously limits its application as a structural material. Carbon fiber has good high-temperature mechanical and thermal properties, and has good physical and chemical compatibility with silicon carbide.
