CARBON FIBER Synthetic fiber filaments of 5–10 μm of diameter.
Principally composed of carbone.
Fabricated from poliacrilonitrile.
Has mechanic properties like steel’s ones
Light like plastic
+ strength than steel

History
In 1958, Roger Bacon.
Technic center, Carbide Parma Union.
Origin: -First for espacial industry -First fibres were created by carbonitation -First fibres had 85% of carbone

FIBERGLASS
Fiber reinforced polymer
Made of a plastic matrix reinforced by fine fibers of glass
It’s a lightweight, extremely strong, and robust material

Origin
It was originated in an accident
People were heating food on stones
Fusion of sand with fire
Small glass filaments were formed
