Abstract:

A bi-directionally corrugated sandwich construction for use in applications requiring high-strength, light-weight components is disclosed. The sandwich construction comprises first and second face sheets positioned essentially parallel to and spaced apart from each other and having a core there between. The core has two sets of corrugated strips which have planar peaks and troughs positioned at regular intervals. The strips of the first set are positioned parallel to and spaced apart from each other with the peaks and the troughs in phase with each other such that parallel rows of troughs are formed perpendicular to the strips. The strips of the second set are positioned parallel to each other with the peaks and troughs in phase with each other, and are positioned perpendicular to the first set of strips in the rows of troughs formed thereby. The sandwich construction is made by forming a first piece comprising one face sheet and the first set of strips, forming a second piece comprising the other face sheet and the second set of strips, and then fixing the two pieces to each other so that the strips of the second set fit into the rows formed by the strips of the first set.
