New Low FST High Temperature Core Material from Diab

30 April 2007

DIAB has added a new core material to its range that it says offers excellent FST (fire, smoke and toxicity) properties coupled with good mechanical and processing characteristics.

Designated Divinycell F, the new material has been developed by Diab primarily for the commercial aircraft and public transportation markets. According to Diab, it more than exceeds the USA and European regulatory requirements for aircraft interiors and the European train FST requirements.

Divinycell F is compatible with most common composite manufacturing processes up to 220°C (428°F) cure cycles, including pre-pregs and infusion. When used with most pre-pregs it does not require the use of a film adhesive. It is also compatible with the most common thermoplastic and thermoset resins including the epoxies and modern phenolics used by both aircraft and train manufacturers.

Diab is targeting the core at applications such as aircraft, train and subway interiors including wall paneling, ceiling modules, luggage bins and doors/lockers. Its close cell structure makes it suitable for galleys and toilets.

The new material will be manufactured in a dedicated production facility that is close to Diab’s existing DeSoto, Texas, operation. Initially, Divinycell F will be available in three densities - 50, 90 and 130 kg/m3 (3.1, 5.6 and 8.1 lb/ft3) and can be supplied in both plain sheets and kit form.
