Abstract
Abstract The present invention relates to apparatus for producing a carbon or boron fiber reinforced composite material for use in the manufacture of blades for gas turbine engines. The apparatus consists of a number of aerofoil section formers mounted on a rotatable drum means for winding a continuous fiber or bundle of fibers under tension onto the formers, a source of curable matrix material located adjacent the drum, and means for curing the matrix material.
