Analysis reveals enhanced oxidation resistance in carbon fiber felt, suggesting durability in electromagnetic shielding.
The article presents the results of a study of the resistance of carbon fiber felt “Carbopon-B-22”, actively used as highly effective broadband electromagnetic radiation screens and radio-absorbing materials, to oxidation under the influence of molecular oxygen during seven years of storage at room temperature. Felt samples annealed at temperatures from 600 to 720 °C were studied to obtain the surface resistance of the material “Carbopon-B-22” from 1100 to 100 Ohm. An increase of 1.7–1.8 times in surface resistance compared to the initial value was noted. The obtained data on the long-term stability and reliability of the properties of the material “Carbopon-B-22” can contribute to new research and development in its application in various fields.
