3 Corecell™ A-Foam The Ultra Tough Foam n Extremely resistant to impact, slamming and fatigue n Highly thermoformable n Suitable for dynamically-loaded structures n Ideal for resin infusion n Superior styrene and heat resistance to linear PVC foam Introduction Corecell™ A-Foam is the original Corecell™ material, developed because of frustrations with PVC core technology in marine sandwich structures. Corecell™ A-Foam is well known for its incredible toughness and resistance to cracking, which comes from its high ductility. ToughFar higher shear elongation than balsa or cross-linked PVC. This high shear elongation is directly related to toughness. Shock, impact and slamming resistanceCorecell™ A-Foam is specifically designed for dynamic loading. No other core material is as safe in a marine environment. High styrene and temperature resistanceCorecell™ A-Foam and Corecell™ P-Foam have excellent styrene and heat resistance. This sets Corecell™ apart from other ductile core materials. ProvenApproved by American Bureau of Shipping (ABS), Lloyds Register of Shipping, Det Norske Veritas (DNV) and Germanischer Lloyd (GL) and tested in the world’s toughest yacht races. Typical Applications Corecell™ A-Foam can elongate up to 65% in shear before failure, making core shear failure in a laminate almost impossible. Tests and experience show that Corecell™ A-Foam is the most reliable core material for dynamic loading situations where PVC and balsa may fail due to poor shear elongation properties. This reliability has made Corecell™ A-Foam the preferred choice amongst offshore yachtsmen for twenty years. For the manufacturer, Corecell™ A-Foam offers the benefit of high resistance to styrene and other chemicals and better thermal stability than linear-PVC foam. Corecell™ A-Foam is also highly thermoformable, which is useful in many applications where cutting the core material is undesirable. Corecell™ A-Foam is available in every resin infusion format and is compatible with polyester, vinylester and epoxy resin systems. The low resin absorption characteristics of Corecell™ and it’s unique knife cut formats deliver higher performing infusions, low resin cost and low weight. Gurit’s global technical team have 10 years experience in resin infusion and offer on-site support for Corecell™ customers. This combination makes Corecell™ the most reliable resin infusion package available.
