Composites have grown in popularity for marine use because they offer a more practical alternative to wood or steel. Favoured for their low magnetism and resilience to shocks, they are also light, strong in tension, stiffer for their weight than steel or aluminium and fatigue resistant. They do not corrode in the marine environment and absorb vibrations, are low maintenance and can be fabricated into complex shapes. Composites simplify outfitting and provide strength and resilience to withstand wave induced shock loads. Composites also have suitable marine fire approvals.
In the shipbuilding industry, ALUCORE® plays an important role due to fire protection standards and the necessary weight reduction. Thanks to its very light weight combined with its economic workability, the composite panel is used – particularly in the interior of the ship – for the ceilings, walls or furniture and in the outer area for balcony partitioning. In all the applications, the material offers optimum strength values at the same time.
Alucobest® panels offer the very latest in composite technology for interior and exterior cladding and is available in a standard range of colours, metallic, brush and mirror finishes. A standard PVDF coating is applied to the aluminium coil prior to lamination into a composite panel. The aluminium coil is processed via a continuous coil coating process and stoved at temperatures between 200 - 2600C. Lighter than solid aluminium,these panels are rigid and offer high strength with excellent torsion and bending strength. Coated with a PVDF resin, the panels withstand extreme weather conditions and the possibility of acid, alkali and salt spray corrosion is minimised. They are also unaffected by temperature change and the long term bask of ultra violet rays. The core of the panel comprises of Viscoelastic high molecular resin preventing cracking or breaking, yet providing high strength, stiffness and impact resistance. Compared to other materials of the same weight (steel, solid aluminium, tile, plywood etc) these panels have a greater sound transmission loss. Panels are fire resistant to BS476 PT 7 Class 1 & BS476 PT 6 Class 0.
KAPA®tech is an innovative, fire certified lightweight foamboard. The pioneering composition of PUR foam and aluminium skins combines lightweight with rigidity for exterior & interior use. It has resistance to humidity and good weatherability as well as good dimensional stability and stiffness. Kapatech also has good insulating properties and can be easily processed and fixed. It is used for insulation, ceilings, interior fittings, cabins, bases for doors and air ducts.
Bondal® is a sandwich sheet, composed of two Galfan® galvanized steel plates (continuously hot dip galvanized steel with 5% aluminium) or aluminium plates (EN AW 5754 H12/H22) with a viscoelastic core layer. The composition of the viscoelastic layer gives Bondal® a very high loss factor.
The product is mostly used as a low-noise (sheet) structure in machine building, yachtbuilding and shipbuilding, hoppers, partition walls, floors, footbridges, pipeline insulation and numerous other applications.
The sandwich sheets can be cut, drilled, punched or sawn like normal plates. Distorting (bending, angle folding, scoring) the material is no problem if the sheets can move independently from one another. Mechanical connections can be applied without advance measures. There are guidelines for welding.
