Patent number: 8857764Abstract: Techniques and apparatus for providing a fly away caul plate are disclosed. In an embodiment, a method for curing a composite structure includes placing a pre-cured caul plate proximate an uncured composite lay-up, the lay-up may or may not include one or more stiffeners extending substantially perpendicular to the lay-up surface, the caul plate including an aperture for receiving the at least one stiffener. A force may be exerted against the caul plate to engage the composite lay-up. Heat and/or pressure may be applied to the composite lay-up to cure the stiffener panel and co-bond the caul plate to the composite lay-up.Type: GrantFiled: August 9, 2012Date of Patent: October 14, 2014Assignee: The Boeing CompanyInventors: Thomas A. Albertson, Karl R. Bernetich, Robert J. Freeman
