Patent number: 7770457Abstract: The invention relates to pseudo porosity standards, and methods for their manufacture and use, which substantially mimic the effect porosity has on ultrasonic sound as it passes through a composite laminate, such as a metallic interleaved composite laminate. An ultrasonic inspection reference standard for composite materials having porosity may include a member having at least one thickness, at least one metallic shim, and at least one mesh. A plurality of metallic shims and meshes may be disposed in alternating layers within the member. The member may be manufactured from a fiber-free polymer resin using a stereo lithography process. Use of the mesh may produce a standard which transmits ultrasonic energy, with the mesh scattering and attenuating the energy. Use of the metallic shim may aide in modeling a metallic laminate.Type: GrantFiled: October 13, 2006Date of Patent: August 10, 2010Assignee: The Boeing CompanyInventors: Roger W. Engelbart, Christopher M. Vaccaro, April L. Beisiegel

Patent number: 7762120Abstract: The invention relates to tapered reference standards, and methods for their manufacture and use. An ultrasonic inspection reference standard for tapered, composite materials may include a member having at least one tapered section. The member may be manufactured from a fiber-free polymer resin using a stereo lithography process. The tapered reference standards may substantially mimic the affect on ultrasonic sound passing through tapered sections in composite laminates.Type: GrantFiled: December 1, 2005Date of Patent: July 27, 2010Assignee: The Boeing CompanyInventors: Christopher M. Vaccaro, April L. Beisiegel, David A. Lilienthal

An ultrasonic inspection reference standard for composite materials having porosity may include a member having at least one thickness and at least one mesh. The member may be manufactured from a fiber-free polymer resin using a stereo lithography process. Use of the mesh produces a standard which transmits ultrasonic energy, with the mesh scattering and attenuating the energy. The manufactured reference standard may replace more costly porous, fiber-reinforced, composite reference standards in the aircraft industry and in other non-aircraft applications.Type: GrantFiled: November 17, 2005Date of Patent: July 13, 2010Assignee: The Boeing CompanyInventors: Christopher M.

Patent number: 7694546Abstract: The invention relates to pseudo porosity standards, and methods for their manufacture and use, which may substantially mimic the effect porosity has on ultrasonic sound as it passes through a composite laminate. An ultrasonic inspection reference standard for composite materials having porosity may include a member having at least one thickness. The member may be defined by at least one hollow, non-spherical shaft. The member may be manufactured from a fiber-free polymer resin using a stereo lithography process. The non-spherical shaft may scatter and attenuate ultrasonic energy. The reference standard may replace more costly, porous, fiber-reinforced, composite reference standards in the aircraft industry and in other non-aircraft applications.Type: GrantFiled: February 16, 2007Date of Patent: April 13, 2010Assignee: The Boeing CompanyInventors: Roger W. Engelbart, Christopher M. Vaccaro, April L. Beisiegel

Patent number: 7617714Abstract: The invention relates to pseudo porosity standards, and methods for their manufacture and use, which substantially mimic the effect porosity has on ultrasonic sound as it passes through a cored composite laminate having porosity. An ultrasonic inspection reference standard for cored composite laminates having porosity may include a member having at least one thickness, at least one core, and at least one mesh. The member may be manufactured from a fiber-free polymer resin using a stereo lithography process. Use of the mesh may produce a standard which transmits ultrasonic energy, with the mesh scattering and attenuating the energy. Use of the core may aide in modeling a cored composite laminate. The manufactured reference standard may replace more costly porous, cored, composite laminate reference standards in the aircraft industry and in other non-aircraft applications.Type: GrantFiled: December 6, 2006Date of Patent: November 17, 2009Assignee: The Boeing CompanyInventors: Roger W.

Patent number: 7509832Abstract: The disclosure relates to pseudo porosity standards, and methods for their manufacture and use, which may substantially mimic the effect porosity has on ultrasonic sound as it passes through a composite laminate. An ultrasonic inspection reference standard for composite materials having porosity may include a member having at least one thickness and at least one discrete wire. The member may be manufactured from a fiber-free polymer resin using a stereo lithography process. The discrete wire may scatter and attenuate ultrasonic energy. The reference standard may replace more costly, porous, fiber-reinforced, composite reference standards in the aircraft industry and in other non-aircraft applications.Type: GrantFiled: January 31, 2008Date of Patent: March 31, 2009Assignee: The Boeing CompanyInventors: Christopher M.
