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

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…
