Patent number: 8393116Abstract: An elevated platform system includes a base support structure and a plurality of fiber reinforced polymer composite panels. The base support structure includes pilings secured to a ground surface and attachment cradles coupled to the pilings. The attachment cradles are in electrical continuity with the ground surface. The fiber reinforced polymer composite panels include a panel body portion, fibrous material surrounding the panel body portion, a non-conductive matrix forming at least a portion of an outer-most layer of the fiber reinforced polymer composite panel, and an electrically-conductive layer at least partially embedded in the non-conductive matrix. The fiber reinforced polymer composite panels are coupled to the attachment cradles, such that the electrically-conductive layer of the fiber reinforced polymer composite panel is in electrical continuity with the ground surface.Type: GrantFiled: February 29, 2012Date of Patent: March 12, 2013Assignees: Composite Advantage, LLC, Canadian Mat Systems, Inc.Inventors: Scott R. Reeve, Andrew K. Loff, Shawn Beamish

Patent number: 8361609Abstract: A composite structure comprising: a first stack comprising a plurality of plies of composite material and at least one ply of self-healing material, the ply of self-healing material comprising a plurality of containers each containing a curable healing liquid; and a second stack comprising a plurality of plies of composite material, the stacks being joined together at a bond line. By placing a ply of self-healing material in one of the stacks (preferably relatively close to the bond line) the ply of self-healing material can resist the propagation of cracks between the first stack and the second stack. Preferably the global strength of the first stack is greater than the global strength of the second stack.Type: GrantFiled: April 2, 2009Date of Patent: January 29, 2013Assignee: Airbus Operations LimitedInventor: Enzo Cosentino

Patent number: 8349438Abstract: An insulative material and a method of forming the insulative material are provided. The insulative material is configured to change shape in response to temperature and thus, for example, the insulative material may become more insulative as the temperature decreases. For example, the insulative material may include a plurality of fibers that change shape, such as by curling, in response to decreases in temperature, thereby correspondingly changing the insulative properties.Type: GrantFiled: January 3, 2008Date of Patent: January 8, 2013Assignee: The Boeing CompanyInventors: Trevor M. Laib, Henry V. Fletcher, III, Bradley J. Mitchell
