Extruding a plurality of fibres, passing the fibres into a bed of a powdered thermoplastic, causing the fibres to converge while they are in the bed so that they form an impregnated bundle, and heating the bundle to a temperature above the melting point of the thermoplastic so that the thermoplastic flows to produce a matrix around the fibres. The bed of powdered thermoplastic is preferably fluidised.
