Each element has a plurality of upper plates and a plurality of lower plates, the plates being aligned, parallel and staggered, with interconnecting webs between the upper and the lower plates, respectively. Several elements are interwoven and bonded to make a panel having a face comprising the upper plates and a back comprising the lower plates. Posts projecting from the back faces of the upper plates improve the strength of the panel.</p> |
