CALCARB® CBCF

A unique microstructure…

CALCARB® CBCF is made up of carbon fibres measuring just a few millimeters in length, emanating from rayon fibres. These fibres are interconnected in a matrix produced by the carbonisation of phenolic resin.

The material is then vacuum-treated at temperatures above 2,000°C to ensure its temperature stability and the absence of outgassing. As a benchmark, the material contains no more than 500 ppm of impurities. Impurity levels below 20 ppm can be achieved through a halogen purification process.
