| A recent product, now five years old, Nidaplast is an extruded polypropylene honeycomb, coated on both faces by a non-woven polyester. Its widespread uses extend from public buildings including water treatment plants through to the composites industry. To all these cases the honeycomb structure brings its well-known physical and mechanical properties of lightness and strength. In addition, the flexible coating on the faces allows easy fabrication which is not the case for normal honeycombs. The polypropylene offers chemical inertness and non-toxicity. |

| In the last two decades, the Finite Element Method has been growing as a powerful tool for the structural analysis of the ship hull, but in nautical construction the use of this method has been related mainly to steel or aluminium hulls. In a metallic structure the material is homogeneous and isotropic and the plate, or the stiffened plate, behaves as an orthotropic plate, which means orthogonally anisotropic with three mutually perpendicular planes of symmetry; on the contrary, when considering a composite hull panel the scheme ought to be different, because there arise two different problems, which ensue from the structural characteristics of the composite sandwich panel. Firstly, the Element Stiffness Matrix must take into account the natural anisotropy... |
