Patent number: 9475964Abstract: A method and apparatus comprising a sol-gel solution. Zirconium n-propoxide is aged in a solvent to form a first part for the sol-gel solution. The first part is combined with deionized water to form a second part for the sol-gel solution. Aminoaryltrialkoxysilane is combined with an alcohol to form a third part for the sol-gel solution. The third part is combined with the second part to form a mixture for the sol-gel solution. The deionized water, or the alcohol, or a combination thereof is combined with the mixture to form a solution. The solution is aged to form the sol-gel solution comprising a mole balance ratio of approximately 1:5 between the zirconium n-propoxide and the aminoaryltrialkoxysilane.Type: GrantFiled: December 28, 2015Date of Patent: October 25, 2016Assignee: THE BOEING COMPANYInventors: Kay Youngdahl Blohowiak, Kristin L.

Patent number: 9347868Abstract: Adhesion testing systems, methods of fabrication, and methods of testing are disclosed. Test systems include test coupons with non-metallic test adherends. Test coupons are configured to test bonds to the non-metallic test adherends under peeling stress and/or shearing stress. Test methods are simplified and rapid as compared to standard adhesion tests and include methods of accelerated environmental testing. Test methods also are adapted for qualitative and quantitative measurement of bond performance.Type: GrantFiled: December 11, 2013Date of Patent: May 24, 2016Assignee: The Boeing CompanyInventors: Peter J. Van Voast, Kay Youngdahl Blohowiak, John Christopher Osborne, Marcus Anthony Belcher
