Patent number: 11028273Abstract: The present disclosure is generally directed to a primer saturated carrier medium assembly including a carrier medium having a front face and an opposing rear face, a primer saturating the carrier medium between the front face and the opposing rear face, and removable film impenetrable to the primer covering opposite faces of the carrier medium. A method of applying primer to a surface includes applying a face of a primer saturated carrier medium to contact a surface, and curing the primer saturated carrier medium on the surface. A structure includes a primer saturated medium including a carrier medium having a front face and an opposing rear face, and a primer saturating the carrier medium between the front face and the opposing rear face. The structure further includes a surface adhered to the primer on one face of the primer saturated medium.Type: GrantFiled: April 3, 2014Date of Patent: June 8, 2021Assignee: THE BOEING COMPANYInventors: Michael W.

Patent number: 10336019Abstract: An in-situ double vacuum debulk (DVD) composite repair system designed to produce partially or fully cured autoclave-quality hot-bond composite repairs on contoured structures. The system provides vacuum pressure for hot bond repairs to be performed on flat and contoured structures using one set-up capable of debulking (partially curing) and then fully curing composite repairs on composite and metallic aircraft structures. The use of in-situ DVD also eliminates handling of the patch/adhesive when transferring from an off-aircraft DVD chamber to the repair site on the aircraft. This can increase the probability of successful repairs because the possibility of contaminating and misaligning the adhesive and repair patch are eliminated.Type: GrantFiled: February 13, 2015Date of Patent: July 2, 2019Assignee: The Boeing CompanyInventors: Karl Edward Nelson, Michael W. Evens, John F. Spalding, Jr., James D. Chanes, Joel P. Baldwin, Paul S. Rutherford

Patent number: 9133365Abstract: There is provided a high temperature hybridized molecular functional group adhesion barrier coating for a composite structure. The coating has one or more hybridized molecular functional groups attached to a composite surface of the composite structure, wherein the one or more hybridized molecular functional groups are hybridized through a chemical derivatization process. The coating further has one or more chemical derivatization compounds attached to the one or more hybridized molecular functional groups via a condensation reaction. The coating is resistant to high heat temperatures in a range of from about 350 degrees Fahrenheit to about 2000 degrees Fahrenheit, and the coating is a thermally protective, toughened adhesion coating that mitigates effects of a hostile operating environment.Type: GrantFiled: December 12, 2014Date of Patent: September 15, 2015Assignee: The Boeing CompanyInventors: Eugene A.

Publication number: 20150198520Abstract: Disclosed are systems and methods of creating altered adhesive bonded joints between metal or composite substrates, including bonds that are weaker in strength than selected reference bonds. One method of creating an altered adhesive bond includes providing a first substrate and a second substrate, selecting a manufacturing process having a plurality of steps designed to produce a desired, or reference, adhesive bond having a desired strength, and selectively altering at least one of the plurality of steps during performance of the manufacturing process to produce an altered bond between the first substrate and the second substrate, the altered bond having an altered strength that is weaker than the strength of the desired adhesive bond. The systems may include systems that may be utilized to create the altered adhesive bonds and/or test standards.Type: ApplicationFiled: January 10, 2014Publication date: July 16, 2015Applicant: The Boeing CompanyInventors: Allan Joshua SLOCUM, Megan Nicole WATSON, Joel P.
