Abstract: Method of manufacturing an integral thermoset infused fibre reinforced composite, structural stator vane ring for a core inlet, a bypass duct, or an air intake of a gas turbine engine. The method comprises winding fibre reinforcement material around a mandrel to form an inner annulus preform; providing a plurality of vane preforms comprising fibre reinforcement material, arranging the plurality of vane preforms around the inner annulus preform, and connecting each of the plurality of vane preforms to the inner annulus preform using a fibre jointing method; winding fibre reinforcement material around the plurality of vane preforms to form an outer annulus preform and connecting the outer annulus preform to each of the plurality of vane preforms using a fibre jointing method to produce a stator vane ring preform; and infusing a thermoset resin into the stator vane ring preform and curing the resin to form the integral stator vane ring.

Abstract: There is disclosed a vane for a gas turbine engine, the vane comprising a three-dimensional weave of composite material. The vane is hollow to define a hollow core, wherein the vane has a maximum thickness (T), and a maximum wall thickness (WT) between an inner surface and an outer surface in a direction normal to the outer surface, wherein WT≤0.1T. Also disclosed is a method of manufacturing a composite vane for a gas turbine engine, the method comprising: forming a preform for the vane comprising a three-dimensional weave of composite material; and curing the preform. The preform has an internal hollow region, and the cured vane has a maximum thickness (T), and a maximum wall thickness (WT) between an inner surface and an outer surface in a direction normal to the outer surface, wherein WT≤0.1T.

Abstract: The present disclosure relates to a variable stator vane and a method of fabricating the variable stator vane of a gas turbine engine. The method includes providing at least one fibre sheet. The method further includes rolling the at least one fibre sheet around a mandrel to form a spindle section of the variable stator vane. An excess of material of the at least one fibre sheet remains after forming the spindle section. The method further includes using the excess of material of the at least one fibre sheet to form the at least one aerofoil section of the variable stator vane.
