Patent number: 6375779Abstract: A lightweight, three dimensional structural article having low radar reflectivity characteristics and good mechanical properties is fabricated from a syntactic foam core having a structural outer skin. A syntactic foam sealing adhesive film is applied to the surface of syntactic foam core and under the outer skin to both seal the foam core and adhere the outer skin. The syntactic foam sealing adhesive is formulated to provide a uniform layer and to reduce the fabrication time and labor while improving the overall radar absorbing characteristics of the structural article.Type: GrantFiled: October 5, 1999Date of Patent: April 23, 2002Assignee: McDonnell Douglas Helicopter CompanyInventors: James L. Melquist, Walter Phillips, Paul L. Kuhl

Patent number: 6291071Abstract: A composite structure is made by first furnishing a skin layer made of a composite material of quartz fibers embedded in an uncured cyanate ester-resin matrix. A transition layer of a first epoxy resin is applied to the skin layer. The skin structure including the skin layer and transition layer is cured at a first temperature and post cured at a second temperature greater than the first temperature. A bonding layer of a second epoxy resin is thereafter applied to the bonding surface of the transition layer, and a substrate is contacted to the exposed face of the bonding layer. The second epoxy resin is cured at a third temperature no greater than the first temperature.Type: GrantFiled: December 30, 1999Date of Patent: September 18, 2001Assignee: McDonnell Douglas Helicopter Co.Inventors: Paul C. Kuhl, Rudy Cesena, Don J. Bridges, Edward S. Harrison, James L. Melquist

Patent number: 6168736Abstract: A low-density, syntactic foam material is provided according to the invention. The syntactic foam material is prepared by mixing together a plurality of microballoons and a finely divided solid thermosetting resin. Fibers are also preferably incorporated into the material during processing to impart specific properties. The mixture is heated to allow the thermosetting resin to flow and wet the microballoons in the mixture. The mixture is then cured to set and crosslink the thermosetting resin to form the syntactic foam of the invention. The syntactic foam material has highly uniform properties and can be used in aerospace applications.Type: GrantFiled: February 10, 1999Date of Patent: January 2, 2001Assignee: McDonnell Douglas CorporationInventors: Edward S. Harrison, Donald J. Bridges, James L. Melquist

Patent number: 6083264Abstract: An implant device material is provided for replacement or augmentation of living bone tissue involving a thermoplastic syntactic foam material formed from microballoons, a polymer such as polyetherimide which wets and binds the microballons into an array, and interstitial space is present between the microballoons bound into the array to create porosity. A fiber material can be embedded within the array. The thermoplastic syntactic foam material is highly biocompatible and stable with no apparent adverse effects on a recipient. The implant device material also effectively conducts bone into the porous implant via its controlled interstitial porosity. The implant material also can be readily molded or machined into complex structural shapes, density and porosity, such that it can be closely tailored to mimic the natural bone tissue to be replaced.Type: GrantFiled: June 30, 1998Date of Patent: July 4, 2000Assignee: McDonnell Douglas CorporationInventors: David W. Wood, James L. Melquist, Walter A. Phillips, Donald J. Bridges

Patent number: 5849234Abstract: A radome structure has an outer first layer of a fiber-reinforced composite material of quartz fibers in a noncrystalline cured oligomeric cyanate ester pre-polymer. A second layer of a syntactic foam underlies and is bonded to the first layer. A third layer of the same fiber-reinforced composite material (although possibly of different thickness) underlies and is bonded to the second layer. A fourth layer of the syntactic foam underlies and is bonded to the third layer. A fifth layer of the same fiber-reinforced composite material (preferably of the same thickness as the first layer) underlies and is bonded to the fourth layer. The structure is formed by layup of the first layer inside a female mold, and successively shaping the remaining layers and tacking them to each preceding layer. The shell produced in this manner can be joined to conforming shells.Type: GrantFiled: July 15, 1997Date of Patent: December 15, 1998Assignee: McDonnell Douglas Technologies, Inc.Inventors: Edward S. Harrison, James L. Melquist, Leland H. Hemming
