Coating of microporous glassy carbon with nonporous surface layer

The samples are coated with the same resin which was used in manufacturing the precarbonized samples. The above manufacturing method gives carbon-carbon composites where the advantages of microporous glassy carbon (the possibility to manufacture large samples, the lightness of material and the rapid carbonization process) are combined with the advantages of nonporous glassy carbon (the resistance against impenetration of gases and liquids and good chemical resistance). 2pp 1fig
