Abstract
The invention provides a spun yarn comprising recycled carbon fiber, and a method for the production thereof. The recycled carbon fiber comprises discontinuous carbon fiber and, optionally, continuous carbon fiber, and may be recycled from various sources, such as end-of-life waste and manufacturing waste. The yarn which is produced shows the required degree of strength and durability, and can be used in all conventional composite manufacturing operations where virgin yarn is currently employed, such as woven fabric manufacture, unidirectional fabric manufacture, filament winding, pultrusion and the like.
