DIAB Improves Divinycell F Core Production Output to Satisfy Forecast Demand

With significant growth in its worldwide aerospace business, DIAB is ramping up production for high-performance composite foam core Divinycell F to meet forecast demand.

According to DIAB, growth has been driven by a considerable increase in orders from associated “buyer furnished equipment” provided by Original Equipment Manufacturers (OEMs). It says that, as Divinycell F is now the preferred lightweight composite core material for aircraft interior applications, DIAB’s huge increase in production capacity will give customers the advantage of shorter lead-times.

The forecast growth in Divinycell F sales has been strengthened by DIAB’s valued-added services, which include a broad range of shaping and kitting services. Lennart Thalin, DIAB EVP Americas & Global Aerospace, remarks “Customers recognise the value of DIAB’s semi-finished parts for direct use in their production processes.“

DIAB says its consistent quality, cost advantage and on-time delivery is now enabling many OEMs to switch from using traditional Nomex honeycomb to DIAB’s polyether sulfone-based (PESU) recyclable foam core material. The use of foam core reduces weight and overall cost relative to comparable honeycomb core products thanks to Divinycell F’s better surface finish, less edge filling and less labour hours.

As a fully recyclable material made with sustainable thermoplastic resins, Divinycell F upholds DIAB’s commitment to reduce the environmental impact of potentially harmful materials such as phenols and acrylics. DIAB explains that its efficient production also minimises waste by reusing excess material back into the manufacturing process.

Divinycell F is now an approved material by numerous aircraft OEMs. This includes several programs running on the Airbus A350. Divinycell F’s 3-D design freedom and four core densities make it suitable for many cabin applications, such as:

  • Environmental Conditioning System (ECS) duct work, ceiling and decorative fascia panels using 40Kg/m3
  • PSU module platforms, sidewall panels, medical stretchers, trolleys, premium seat structural components, lavatory and galley components using 50Kg/m3
  • IFE racking, cargo bay components, door surrounds, stowage components and all interior monuments using a combination 50 and 90Kg/m3
  • Radomes and panel edge filler as a replacement to PU foam using 130Kg/m3

DIAB is making further planned investment in Sweden to support the company’s global market offering of precision machining and shaping services. Lennart Hagelqvist, DIAB Group President & CEO, affirms “At DIAB, we are totally committed to offering competitive solutions for aerospace customers, and to working in close partnership to drive cost down with optimum design solutions and production efficiencies.”
