Patent number: 9738051Abstract: Adjoining edges of adjacent honeycomb core panel sections are mechanically interlocked. In one embodiment, the method includes forming a first edge along a first cellular core panel section. The first edge includes a first plurality of edge cell walls along the first edge. The method further includes forming a second edge along a second cellular core panel section, wherein the second edge includes a second plurality of edge cell walls along the second edge. The first edge is positioned proximate to the second edge. At least a portion of at least one of the first plurality of edge cell walls is mechanically interlocked with at least a portion of at least one of the second plurality of edge cell walls to form a joint therebetween. A composite structure may be at least partially produced by such a method.Type: GrantFiled: February 2, 2016Date of Patent: August 22, 2017Assignee: Rohr, Inc.Inventor: Alan Richard Douglas

Patent number: 7861394Abstract: A method for making a composite tubular structure, such as the inner skin of an acoustic liner, includes providing a tool that is adjustable between a molding position and a non-molding position. The tool has a base on which are mounted a plurality of sectors, each sector having an outer panel provided with a predetermined shaped surface. The predetermined shaped surface corresponds to a portion of the contour of the tubular structure to be formed. At least one of the sectors is fixed relative to the base while the remaining sectors are movable in a radial direction and separable from all the other sectors. The method includes adjusting the movable sectors until the tool is in the molding position, applying composite material on an outer surface of each sector, curing the composite material to form an inner skin, and removing the inner skin from the outer surface. The thus-formed composite tubular structure may be remounted on the tool for bonding to additional exterior layers.Type: GrantFiled: March 19, 2010Date of Patent: January 4, 2011Assignee: Rohr, Inc.Inventors: Alan Richard Douglas, Gabriel Joseph Gutierrez, Mark Alan Ramsey, Steven Mark Ranum

The predetermined shaped surface corresponds to a portion of the contour of the tubular structure to be formed. At least one of the sectors is fixed relative to the base while the remaining sectors are movable in a radial direction and separable from all the other sectors. The sectors are provided with air bearings to facilitate movement along a radial direction. Splice plates are used to form a joint between the outer panels of adjacent sectors. After composite material is applied on the outer panels, a vacuum bag is formed to surround the composite material and also the joint areas on the inner surface of the tool. The entire tool may be placed in an autoclave for curing.Type: ApplicationFiled: March 19, 2010Publication date: July 8, 2010Applicant: Rohr, Inc.Inventors: Alan Richard Douglas, Gabriel Joseph Gutierrez, Mark Alan Ramsey, Steven Mark Ranum
