2. Description
• Consist of fibers composed of carbon atoms
• Carbon atoms are bonded together
• Combined with other materials to form a composite
• The atomic structure is similar of graphite
consisting of sheets of carbon atoms

3. Origin and history
• 1958
Roger Bacon created high-performance
carbon fibers
• were manufactured by heating strands of rayon
This process proved to be inefficient
• 1970
Carbon fiber made from a petroleum pitch

4. Specific properties
• High resistance to mechanics
• Low density
• High producction price
• Resistance of external agents
• Big capacity of thermal insulation
• Resistance of the temperature variation

5. Uses
• Aeronautical industry
• Motoring industy
• Boats and bicycles
• Roller skate, tennis racket, flat
• Notebook, tripod, fishing rod

7. •
•
•
•
A group of many fibers
Made by extruding thin strands in fibers
Extremely fine
Obtained when liquid glass flows trought an
espinerette

8. Origin and history
• Heating and drawing glass’ techniques have been
known for millennia
• Manufacturing glass fibres techniques are recent
• Dubus Bonnel was the first who used it
• He used it as thread

9. Specific properties
