ABSTRACT:
A structural sandwich laminate constituted by thin skins, such as aluminum or fiber-reinforced plastic sheets bonded to the faces of a core formed by an array of wood strips having a periodic wave formation. The wavy strips in the array are out of phase with each other and are bonded together at their contiguous troughs and peaks to define an open-celled expanded wood structure whereby the laminate, though light-weight, has high strength.
