SCROLL TO TOP

1.1.1 Forerunner shines

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...

Carbon fiber prices

They are highly dependent on the quality of the carbon fibers and the inspection and testing costs demanded by customers.

We can give a range of sales prices from 20 to 150 euros/kg, staying within classic carbon fiber categories, i.e. without going into very "specific" fibers with very high modulus.

Standardization

Several national standards committees have published standards for carbon fibers (table 2 ). Since 1987, a specialized ISO working group has been drawing up international standards.
