Patent ID: 8677622

Claim:
A method for manufacturing an intake cone in a fiber compound material for a gas turbine engine, the intake cone including a conical part, an attachment part, a fairing part, and a longitudinal axis about which the intake cone rotates at a speed of a fan of a gas turbine engine, and constructed of fibers embedded in a resin and having an interlace, the method comprising: winding a plurality of dry mutually crossing and covering winding layers on a conical molding core at different angles and under formation of the interlace, these winding layers are at least one chosen from essentially straight and widely curved and made of straight strands and include adjacent dry glass fiber strands and dry carbon fiber strands of similar thickness in a conjoined arrangement, the glass fiber strands and the carbon fiber strands individually arranged in an alternating and parallel arrangement within each layer, the glass fiber strands and the carbon fiber strands having a one to one ratio; bringing another mold portion into engagement with the molding core to form a mold cavity in which the dry winding layers are positioned; and subsequently infiltrating the resin into the mold cavity and dry wound interlace such that the resin forms to the mold cavity to form a surface of the intake cone that is smoother than a surface of the winding layers prior to resin infiltration.
