DESCRIPTION
Citation preview
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
Structure
Is similar to graffit’s structure
Carbon atoms arranged in a regular hexagonal pattern.
Amorphous material
Density 1750 Kg/m3
Properties Electric and thermal conductor
High production price
Resistance to extern agents
Thermal insulation
Low density
Resistance to temperature variations
Utilities
Transports
Construction
Sports materials
Transportation industry, aviation, high competition sport

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
Properties
Thermal insulator
Inert to acids
Withstands high temperatures
Stiff and strong in tension and compression
Low production price
Applications
Fiber optic cables
Thermal insulator at construction
Craft products or DIY
Nautical items
Water tanks
NAILON From a family of synthetic polymers
First produced on 1935, Wallace Carothers
One of the most commonly used polymers
First used in a nylon-bristled toothbrush
Characteristics
Very lustrous, semilustrous or dull
High tenacity, elongation and abrasion resistance
Melts instead of burning
Military, carpets and nylon stockings applications
Chemistry conditionsCompact molecular structure
Higher melting point (256 °C/492.8 °F)
Good weathering properties and sunlight resistance
Superior colorfastness
Nailon aplications
Gears, fittings, and bearings
Power tools housings
Strings for acoustic and classical instruments
Manufacture of threads, ropes, filaments, nets…
