Thermal stability of the carbon fibers with SiO2 coating

Thermal stability of the carbon fibers with SiO2 coating

This paper presents the results of a study of silicon dioxide coating deposited on the surface of carbon fiber by the sol-gel method. The effect of the viscosity of the prepared sol-gel solution and the oxidizing properties at elevated temperatures obtained by SiO2 coatings were studied. It was foun...
