| Popis: | The article shows the possibility of applying a silicon dioxide coating on the carbon fiber by the sol-gel method. The evaluation of the protective properties of the obtained coatings at a temperature of 600 ° C is given; the changing of the a coated fiber surface morphology during the destruction process is shown for the first time. The destruction of the carbon fiber surface without coating begins at a soaking time of 120 min, which is accompanied by a significant decrease in the diameter of the fiber. The destruction of the coated carbon fiber surface begins at a soaking time of 360 minutes, the fiber diameter changes insignificantly. The paper shows that the sol-gel coatings slow down the oxidation of the carbon fiber more than 2 times. |
