Fibres

Fibres are pliable hair-like substances, built up by long chains of basic molecules. Fibres are very small in diameter in relation to their length. Long continuous strands of fibers are called filaments. The only natural filament fibre is silk from butterflies or spiders.

Most fibres are organic materials, but a number of inorganic fibres exist.

Fibre's properties depend strongly on both the external and internal fibre structure as well as the chemical composition. Properties therefore vary significantly. Crystalline areas give tensile strength, stiffness and stability, while amorphous areas are weaker but more movable.
