Patent number: 5921754Abstract: A method of manufacturing a composite turbine rotor in which blade coupons are fabricated from flat braided fabrics that have extending axial fibers. The extending axial fibers are then woven between the plies of polar woven fabric which make up the body of the rotor. This preform assembly is then impregnated with resin and cured. The blade coupons make up the blades of the rotor and can be made to have an airfoil shape, a curved shape, or a twisted shape by the use of blade formation tools designed for forming the rotor preform.Type: GrantFiled: August 26, 1996Date of Patent: July 13, 1999Assignee: Foster-Miller, Inc.Inventors: Glenn Freitas, William J. Hurley, Jr., Kevin Keough, Richard Terrazzano, Brian Tweed, Joseph Boyce

Patent number: 5904087Abstract: A braiding machine carrier having a frame; a fiber spool mount attached to the frame; a fiber take-up assembly including a spiral spring; gear train on the frame for mechanically connecting the take-up spring assembly to the fiber spool mount for winding the spiral spring as a spool on the mount rotates; and a magnetic clutch, coupled to the take-up spring assembly, for preventing overwinding of the spiral spring.Type: GrantFiled: July 28, 1997Date of Patent: May 18, 1999Assignee: Foster-Miller, Inc.Inventors: Glenn Freitas, Kevin E. Keough, William J. Hurley, Jr., Richard Terrazzano, Daniel Bullock

Patent number: 5827383Abstract: An improved stiffener reinforced assembly and method. There is a skin member and a stiffener member including a web portion, a flange portion, and a radius region interconnecting the web portion and the flange portion. The flange portion resides on the skin member. A plurality of reinforcing pins are disposed through the radius region of the stiffener member and into the skin member to secure the stiffener member to the skin member.Type: GrantFiled: June 5, 1998Date of Patent: October 27, 1998Assignee: Foster-Miller, Inc.Inventors: Thomas G. Campbell, John J. Harris, Thomas M. Fusco, Sara E. Rosenberg, Glenn A. Freitas, Eric J. Blaney
-
Patent number: 5800672Abstract: An ultrasonic fastening system wherein an ultrasonic transducer is used to insert a plurality of fasteners supported by a compressible member into two components to be joined or a single composite part to be reinforced.Type: GrantFiled: December 26, 1996Date of Patent: September 1, 1998Assignee: Aztex, Inc.Inventors: Joseph S. Boyce, Glenn A. Freitas, Constance L. Magee, Thomas M. Fusco, John J. Harris, Edward Kunkel

Patent number: 5624622Abstract: A reinforced foam core sandwich structure including opposing face sheets, a foam core therebetween, and tow members encapsulated within the foam core and extending between the opposing face sheets forming a support structure within the foam core between the face sheets.Type: GrantFiled: February 7, 1996Date of Patent: April 29, 1997Assignee: Foster-Miller, Inc.Inventors: Joseph S. Boyce, Glenn A. Freitas, Thomas G. Campbell
-
Patent number: 5589015Abstract: A method of and system for inserting reinforcing pins in a composite structure in which a number of reinforcing pins are inserted in a compressible material; the compressible material/pin combination is assembled on the composite structure; ultrasonic energy is applied to the pins; and pressure is applied simultaneously with the application of ultrasonic energy to compress the compressible material and insert the pins into the composite structure to join two laminates or reinforce a single composite structure.Type: GrantFiled: February 13, 1996Date of Patent: December 31, 1996Assignee: Foster-Miller, Inc.Inventors: Thomas M. Fusco, Constance Magee, Glenn Freitas
-
Patent number: 5125179Abstract: A nonmetallic tubular structure and method of making the same comprising a tubular ceramic linear surrounded by a thermal insulating composite tube and an outer braided sleeve of a graphite fiber/epoxy composite tensioned to generate compressive stresses in the ceramic liner and maintained in compression by curing the sleeve while under tension.Type: GrantFiled: April 8, 1991Date of Patent: June 30, 1992Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Thomas G. Campbell, Glenn A. Freitas

Patent number: 4909127Abstract: A braider having a braider bed. The bed has first and second closed tracks defining an intersecting serpentine path. The tracks define an average path which is non-circular. A plurality of yarn package carriers travel along said tracks. Yarns fed from the packages form a braid at a location substantially central of the bed.Type: GrantFiled: January 19, 1988Date of Patent: March 20, 1990Assignee: Albany Research (UK) LimitedInventors: John Skelton, David Brookstein, Glenn A. Freitas
-
Patent number: 4785709Abstract: This invention relates to a braider having a braid ring about which yarns passing from the yarn packages on the carrier to the article being braided traverse or change direction about the braid ring, vibrators being mounted on the ring to vibrate the ring, thereby allowing yarns of high surface friction to pass over the ring thereby reducing the incidence of yarn breakages during braiding.Type: GrantFiled: January 19, 1988Date of Patent: November 22, 1988Assignee: Albany Research (UK) LimitedInventor: Glenn A. Freitas
