Sandwich construction gives designers many new options. It is a technique that can be usefully applied to structures requiring low weight, high strength and good dynamic properties. A sandwich consists essentially of two outer facing layers and a core. The outer layers take up normal stresses in the structure and give it a durable surface. The core keeps the outer layers a constant distance apart, and at the same time takes up the shear forces caused by loading and bending. Unlike conventional I-beams, which are subject to severe local stresses, a sandwich absorbs the load and distributes the stresses over a much larger area. The result is a structure of uniform strength with no weak points.
Divinycell structural cellular plastic has everything that a high performance core material ought to have. Its greatest
advantage is its high strength-to-weight ratio. Others are exceptional dynamic strength, low water absorption and excellent insulating properties. In addition, Divinycell can tolerate temperatures from -200ºC to + 120ºC (-330
to + 250ºF), and is self-extinguishing. Using Divinycell as the loadbearing core adds a number of unique properties that further amplify the superiority of the sandwich concept over conventional construction techniques.
