Abstract
Provided herein is a method for aligning discontinuous fibres comprising: providing a stream of discontinuous fibres in a dispersion medium; applying a shear stress to the dispersion medium to align at least a portion of the discontinuous fibres; and disposing the at least a portion of the aligned discontinuous fibres on a substrate thereby providing a layer of substantially aligned discontinuous fibres. Also provided are discontinuous fibres aligned by such method and a composite material formed from the aligned discontinuous fibres.

A fibre aligning apparatus comprising:
- a shearing element for applying a shear stress to the dispersion medium having an inlet for receiving a stream of discontinuous fibres in a dispersion medium and an outlet;
- such that in use, the stream of discontinuous fibres undergoes shear stress thereby providing substantially aligned discontinuous fibres.
