Publication number: 20190358946Abstract: A method of making a core-stiffened structure includes the steps of providing a honeycomb core having an adhesive disposed on first and second surfaces thereof, providing a first skin and a second skin, and assembling the first skin, the second skin, and the honeycomb core to form the core-stiffened structure. The method further includes the steps of curing the core-stiffened structure and inhibiting at least one of the first skin and the second skin from protruding into at least one cell of the honeycomb core during the step of curing the core-stiffened structure.Type: ApplicationFiled: August 6, 2019Publication date: November 28, 2019Applicant: TEXTRON INNOVATIONS INC.Inventors: James D. Hethcock, JR., KENNETH E. NUNN, JR., CARL A. MAY

Publication number: 20170320289Abstract: A composite core includes a plurality of tubes, each the plurality of tubes comprising a plurality of fibers disposed in a polymeric matrix. Adjacent tubes of the plurality of tubes are adhesively bonded to one another along sides of the adjacent tubes. A method of making a composite core includes the steps of providing a plurality of tubes, each of the plurality of tubes including a plurality of fibers disposed in a polymeric matrix, and adhesively bonding adjacent tubes of the plurality of tubes along sides of the adjacent tubes. A method of making a composite core such that a removable band is included in the core, the removable band being configured to be removable through a procedure subsequent to the cure of the composite core, thereby producing gaps in the core.Type: ApplicationFiled: July 25, 2017Publication date: November 9, 2017Applicant: BELL HELICOPTER TEXTRON INC.Inventors: James D.

Publication number: 20170159280Abstract: Primary architectural hubs useful for providing geodesic structures, the hubs provided enabling a strut configuration interface having increased strength over analogous articles of the prior art. In some embodiments are provided secondary hubs attached to the primary hubs, which provide for truss configurations enabling rectangular apertures such as doors to be affixed to a geodesic structure without compromising the strength of the geodesic structure as a whole, which was the case with prior art geodesic structures.Type: ApplicationFiled: February 6, 2017Publication date: June 8, 2017Inventor: KENNETH E.
