Chemical structure of carbon fibre
WebCarbon (graphite) fibres are very stiff, strong and light filaments used in polymer (usually epoxy) matrix composites for aircraft structures and jet engine parts. Polymer composites containing carbon fibres are up to five times stronger than mild steel for structural parts, yet are five times lighter.

Cellulose is a macromolecule –– a polymer made up of a long chain of glucose molecules linked by C-1 to C-4 oxygen bridges with elimination … WebThe fibre essentially consists of bundles of fibrils that are stiff and strong along their axis but weakly bonded together, as shown in Fig. 14.9. As for carbon fibres, aramid fibres are highly anisotropic with their modulus and strength along the fibre axis being much greater than in the transverse direction.
WebThe raw material used to make carbon fibers is a precursor represented by polyacrylonitrile (PAN, nearly 90% of the carbon fiber's production), whereas the remaining 10% are made from rayon or petroleum pitch. An example of carbon fiber production from PAN is shown in Figs. 3.41 and 3.42. Sign in to download full-size image Fig. 3.41.
