Carbon fiber manufacturing processes
Carbon fibers

The first carbon fibers were made from braids, woven fabrics or a mat of rayon fibers, all fixed to a rigid frame and heated, in the first stage, to 1,000-1,500°C to transform the cellulose into carbon under an inert atmosphere, then eventually to 2,000-2,500°C to obtain greater resistance to oxidation at higher temperatures. No special tension was applied during heat treatment, so the mechanical properties of the resulting carbon fibers were not as...
