After many years of hard work, the structural foam core Divinycell F has been approved by Airbus under AIMS 04-11-000 and ABS5927 standard. “This truly shows that Divinycell F is becoming well recognized and accepted for aircraft interiors”, says Lennart Thalin, EVP Diab Americas & Global Aerospace.
Today Divinycell is used in first and business class seats as well as lavatory interiors, galleys, luggage bins, and window frames for the Airbus 350 XWB. Divinycell F is also used in many other aircrafts from Airbus, Boeing and Embraer.
Divinycell F is a game changer for how composite parts for commercial interiors are made, as it saves up to 20% weight compared to Nomex honeycomb, which translates into substantial cost savings. Divinycell F minimizes the need of labor intensive, and therefore costly, putty, sanding and sweeping steps to achieve a high quality surface finish. Featuring closed cells and minimum water absorption. Divinycell F also eliminates the need for edge filling. Many panel designs even incorporate Divinycell F as an edge close-out material for honeycomb.
Divinycell F withstands high temperatures and exceeds by far all requirements for aircraft interiors when it comes to Fire, Smoke and Toxicity (FST). It also scores far below OSU Heat release requirements.Other benefits of a foam core are improved acoustical and thermal insulation properties compared to honeycomb. Divinycell F adapts to multiple production processes, such as hot and cold forming as well as compressing into different geometries. It is also easy to machine Divinycell F into complex shapes, which gives great design freedom compared to any other material available on the market.
Market Segment Manager Global Aerospace and the “father” of Divinycell F, Chris Kilbourn adds: “Divinycell F is probably the most tested foam core for aircraft interiors. Diab Americas was granted a $4.4 million by the US Army to further develop this product. The development program included intensive testing according to 18 different test criteria, with both A and B basis sampling.”
Divinycell F is a sustainable material for the future. It is fully recyclable and has a low impact on the environment. It can be combined with a thermoplastic skin made of the same polymer, which gives an even greener solution. With production already at a high level, lead times are short – 4-6 weeks from order.
Divinycell F is currently available in four (4) densities: 40, 50, 90 and 130 kg/m3. It can be delivered in 1.6 to 51 mm thickness and standard lengths of 2440 and 2730 mm. Standard width is 610 mm with the possibility of larger sheets with bondlines.
Apart from the foam core supply, Diab supports customers with added value services such as CNC machining and thermoforming kits, ready to be used in our customers’ press or vacuum molding processes.
