Abstract

A structural assembly includes a frame and a plurality of panels. The frame includes a wall that at least partially defines an interior region. The plurality of panels is disposed at least partially in the interior region and is coupled to the frame. The plurality of panels includes a first panel and a second panel. The first panel includes a first surface and a second surface opposite the first surface. The first surface defines a first plurality of depressions and the second surface defines a first plurality of protrusions complementary to the first plurality of depressions. The second panel includes a third surface and a fourth surface opposite the third surface. The third surface defines a second plurality of depressions. The fourth surface defines a second plurality of protrusions complementary to the first plurality of depressions. The first panel is coupled to the second panel.
