Abstract:
1. A structure, comprising a first layer having a faying surface, a side edge, and a first coefficient of thermal expansion; a second layer having a faying surface, a side edge, and a second coefficient of thermal expansion that is different than the first coefficient of thermal expansion; an adhesive layer between the faying surface of the first layer and the faying surface of the second layer, the adhesive layer defining a bondline having a main portion and an edge treatment portion; the faying surface of at least one of the first and second layers including an edge treatment extending along at least a portion of a respective one of the side edges, the edge treatment of the at least one of the first and second layers includes a spacer extending toward an opposing one of the first and second layers and supporting the side edge of the at least one of the first and second layers against deflection; and the edge treatment portion of the bondline corresponding to the edge treatment of the at least one of the first and second layers and being located outside of the main portion and tapering in height from the side edge of the at least one of the first and second layers to the main portion of the bondline.
