Abstract (en)
[origin: WO2014170637A1] A method of manufacturing a fibre preform with aligned discontinuous fibres. A jet of liquid containing discontinuous fibres is directed onto an alignment surface from a nozzle so that the jet meets the alignment surface at an oblique angle and is deflected by the alignment surface into a channel between an opposed pair of channel surfaces. The fibres move along the channel after the jet has been deflected into the channel by the alignment surface. The liquid is removed from the fibres to provide the fibre preform which may optionally be impregnated with matrix to form a composite tape. At least some of the fibres have a length greater than a spacing between the channel surfaces.
