The material has been successfully researched by Academician Zhang Litong of Northwestern Polytechnical University, and won the first prize of National Technology Invention in 2005. The overall technology of the results has been ranked first in the world. The comprehensive performance of materials has reached the international leading level, breaking the international high-tech blockade and advanced weapons to China. The leap-forward development of equipment has far-reaching implications. This achievement is also important for promoting technological advancement in industries such as transportation, new energy, chemical and chemical industries, and machinery.
Successful research on continuous fiber toughened silicon carbide ceramic matrix composites
"Continuous fiber toughened silicon carbide ceramic matrix composite" is a new type of strategic thermal structural material, which is lighter than aluminum and stronger than steel. It is more resistant to high temperature and oxidation ablation than silicon carbide ceramics, and overcomes ceramics. Brittleness. Alternative metal materials can solve the problem of 20%~30% waste of aerospace fuels, meeting the demand for high speed, high precision, high load and long life. The material was only in the 1990s in France and the United States. Stepping into the application research stage, the manufacturing technology and equipment of the material components are tightly sealed to China.
