Application of silicon carbide SiC in polymers. In recent years, studies have found that polymer-based composite materials modified with a small amount of hard inorganic substances can significantly improve their mechanical and thermal properties. Silicon carbide SiC organic-inorganic composite material is a kind of polymer matrix composite material modified with silicon carbide SiC ceramic. Now such composite materials are widely used in the packaging industry, coating industry, electronics industry, automobile industry, and aerospace industries. It is believed that in the near future, as the application field of silicon carbide SiC organic-inorganic composite materials continues to expand and the modification research continues to deepen, silicon carbide powder ceramics will play a greater role in more fields.
