Transcript of carbon fiber

Carbon Fiber
By: Kristian Astwood
Structure
Carbon fiber can be made from
Polyacrylonitrile
Rayon
Pitch(cullulose)
Graphite
Carbon fiber is composed of carbon atoms bonded together to form a long chain
Properties
Carbon Fiber is extremely strong
Extremely stiff
Extremely Light
Polymer spun flat, small and rigid.
Peices strung together to make a strong material.
History
The history of carbon fiber dates back to the late 1800s when it was invented by Thomas Edison. He used carbon fibers as filaments for early light bulbs. His carbon fibers were made out of cellulose-based materials, such as cotton or bamboo, unlike the petroleum-based precursors used today. It wasn't until the late 1950's that high tensile strength carbon fibers were discovered. Rayon became the first precursors used to create these modern fibers. Later it was replaced by more effective materials such as polyacrylonitrile and pitch.
Raw Materials
Manufacture
There is no single formula for a carbon fiber, just like there
is no single formula for graphite or for diamond. Every individual
fiber has a different molecular weight because each fiber has
a different number of atoms within a macroscopic sample of
fibers.
Polyacrylonitrile
Rayon
Pitch(cullulose)
Graphite
Made Mostly from graphite beacause of it's strenght.
Uses
Mainly used for car parts
Artificial Body parts(legs, arms, etc..)
Parts for musical instruments
