Carbon fiber is used for its high strength to weight ratio. When fiber fraction in one direction (typically O° / Warp) is more than 80%, the fabric is called Unidirectional. With carbon fiber, the fiber ratio in O° is maximum to get maximum strength
UD can be woven, stitched or thermobonded.
Those fabrics can be offered in a large variety of gramm-weights, widths are typically < 100 cm but slitted tapes are also possible on demand
