Carbon Fibres
category
Carbon fibres are produced by controlled thermal oxidation and carbonisation of polyacrylonitrile, pitch, or rayon precursor fibres at temperatures from 1000 to 3000 degrees Celsius, yielding filaments of 5 to 10 micrometre diameter with tensile modulus from 230 to 900 gigapascals, tensile strength from 3.5 to 7.0 gigapascals, and density of 1.75 to 2.1 grams per cubic centimetre depending on heat treatment temperature and graphitisation degree.
Role
Provides the highest specific stiffness and strength reinforcement fibre available for structural composite applications in aerospace primary structures, motorsport, wind energy, and high-performance sports equipment, enabling weight savings of 20 to 40 percent over equivalent aluminium structures with superior fatigue resistance in demanding structural applications.
