What are the benefits of carbon fibre? How is it constructed?
Carbon fibres, also known as graphite fibres, are very strong, high strength, stiff and lightweight material composed of carbon atoms chemically bonded together in a long chain. Carbon fibres also exhibit high chemical and thermal resistance. Because of these properties, carbon fibres act as desirable raw material for building high-quality sports equipment, airplanes, robots, etc. Carbon fibres are certainly superior to metal and other kinds of fibres. However, they are also quite expensive. Carbon fibres contain at least 90% carbon and are constructed through decomposition of certain precursor fibres at a high temperature in highly controlled conditions. Precursors such as PAN (polyacrylonitrile), rayon, petroleum, pitch, etc. can be used for making carbon fibres. Construction of carbon fibres happens in three stages- Stabilisation, Carbonisation and Graphitisation. Carbon fibres can also be combined with other strong materials to make Composite materials.
Carbon fiber is made up of long strands of carbon arranged in a straight line. This arrangement makes the bonds between carbon atoms stronger and the resulting material is very light weight. Because of this, carbon fiber makes for a very useful building material. It is ten times stronger than steel and five times lighter. It is commonly used in electronics, sports equipment, and musical instruments
