Abstract
The core of a sandwich panel is formed with projecting nodes, the faces of the nodes being bonded to the face sheets of the panel. The node faces have the central portions thereof excised such that the remaining portion of these faces form flanges. These flanges are bent away from the center plane of the core and are shaped for optimum attachment to the curved panel face sheets without the need for crippling or deforming the node body and so that they enable the formation of a good bonded or brazed joint between the node faces and the face sheets.
