Patent number: 10654246Abstract: A method is provided for forming a composite article to have a primary composite structure and an integral secondary composite structure that extends out of a plane defined by the primary composite structure. The method includes laying-up first plies to construct the primary composite structure. The first plies contain continuous reinforcement material and extend from a first zone that will define the primary composite structure into a second zone that will define the secondary composite structure. During laying-up of the first plies, additional plies are interleaved with the first plies within the second zone but not the first zone. The additional plies originate within a build-up zone between the first and second zones and extend therefrom into the second zone. After interleaving the plies, the build-up zone is deformed to orient the second zone and form the secondary composite structure that extends out of the plane defined by the continuous reinforcement material of the first plies.Type: GrantFiled: November 28, 2012Date of Patent: May 19, 2020Assignee: GENERAL ELECTRIC COMPANYInventors: Ming Xie, Mark Ernest Vermilyea, Bowden Kirkpatrick, Mitchell Harold Boyer, Elliott Keller Schulte, Benjamin Ferrell

Patent number: 9777593Abstract: A hybrid metal and composite spool includes metal rings on an outer diameter of a composite spool shell. Metal rings may include features such as annular or axial dovetail slots. Adhesive layers may be between the metal rings and composite shell which may be connected by a shrink bonded joint. The metal rings may include a single seal tooth ring with an annular radially extending seal tooth. A method for fabricating the spool may include fabricating one or more metal rings with the features therein, positioning the metal rings in place on an outer surface of an uncured composite spool shell of the spool before curing the shell, and curing the shell with the one or more metal rings positioned in place. Alternatively, rings may be heated to a temperature at least sufficient to slide rings over a cured composite shell, and allowed to cool and shrink onto shell.Type: GrantFiled: February 23, 2015Date of Patent: October 3, 2017Assignee: General Electric CompanyInventors: Bowden Kirkpatrick, Nicholas Joseph Kray, Todd Alan Anderson, Stefaan Guido Van Nieuwenhove, Po-Ching Yeh
