Abstract
A load bearing deck structure is made from at least one sandwich panel formed of a ploymer matrix composite material. The sandwich panel comprises a plurality of substantially hollow, elongated core members having side walls, the core members being provided with an upper facesheet and a lower facesheet. Each facesheet is formed integrally with the side walls of the core members and at least one of the side walls is disposed at an oblique angle to one of the upper and lower facesheets so that the side walls and facesheets define a polygonal shape when viewed in cross section.
