Carbon graphite fibres are very stiff strong and light filaments used in polymer usually epoxy matrix composites for aircraft structures and jet engine parts.
Graphite carbon fiber.
Graphite fiber is certain class of carbon fiber.
The main difference between graphite and carbon fiber is the fact that graphite breaks apart easily while carbon fiber is strong.
Carbon fibre composites have better fatigue properties and corrosion resistance than virtually every type of metal including the high strength alloys used in airframe and engine components.
Carbon fibers have several advantages including high stiffness high tensile strength low weight high chemical resistance high temperature tolerance and low thermal expansion.
They are both carbon based which is why some people tend to use the terms interchangeably.
Polymer composites containing carbon fibres are up to five times stronger than mild steel for structural parts yet are five times lighter.
Nippon graphite fiber corporation pitch based carbon fibre granoc has been used in various applications.
Satellite sport industry construction and civil engineering.
The atomic structure of carbon fiber is similar to that of graphite consisting of sheets of carbon atoms arranged in a regular hexagonal pattern.
This difference explains why graphite works well in a pencil and carbon fiber works well in sports equipment airplanes and the space shuttle.
