Carbon Fibre Tenax HTA Multi Filament Tow



Continuous multi-filament TOW.

The most common form of carbon fibre is the high strength, high stiffness form commonly used in composites. These are made by a complicated process from textile pre-cursor yarns made from either Polyacrylonitrile (PAN) or pitch that results in a predominantly graphitic structure highly oriented in the direction of the fibre axis. This high orientation gives them their remarkable properties which include a small negative coefficient of thermal expansion in the axial direction as well as remarkably high specific strength and stiffness.
