A structural panel comprised of a plurality of distinct layers of cylindrical foam elements each covered with a fiber-reinforced composite material. The cylindrical foam elements are arranged in layers such that the elements of adjacent layers are arranged non-parallel to one another. A pair of facesheets are secured to opposing surfaces of the cylindrical foam elements. The structural panel is high in strength, structural stiffness, and yet relatively low in weight, and is suitable for a variety of aerospace and other applications.
