Abstract
A method for producing an annular, fiber-reinforced composite structure comprising (a) forming reinforcing fibers into an annular base preform having an annular flat-plate web and a flange substantially perpendicular to the web, (b) bonding an annular, reinforcing, flat-plate fiber preform to the web of the annular base preform, (c) bonding a cylindrical, reinforcing fiber preform to the flange of the annular base preform to form an integral, annular fiber preform, (d) impregnating the resultant annular fiber preform with a matrix resin, and (e) curing the matrix resin.
