Abstract
A panel structure comprises a frame members defining the perimeter of the panel structure. The frame members have a first side facing outwardly of the panel structure and an opposed side facing inwardly. A panel member extends between the frame members and is engagable therewith. The panel member comprises an inner honeycomb core constructed from cellulosic material and having a pair of opposed side faces and a pair of opposed side panel members having a first side facing outwardly of the panel structure and an opposed side facing inwardly. Each of the opposed side faces is affixed to a respective side of the honeycomb core. The side panels are constructed essentially from material which, when not affixed to the honeycomb core, is non-structural and, when affixed to the honeycomb core, has a tensile strength sufficient to prevent compressive movement of the opposed side of the honey comb core.
