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.
