Technifab Develops Aero Ducting System Featuring Solvay's PAEK-based Structural Parts
Technifab Inc., Avon, Ohio, among the leading solutions providers to the aerospace industry, has developed a new high-performance polymeric foam ducting system that features structural components made of AvaSpire® polyaryletherketone (PAEK) resin from Solvay Specialty Polymers. The new ducting system is a key element of a newly developed aerospace Environmental Control System (ECS) for a major aircraft manufacturer. Solvay made the announcement at the Aircraft Interiors Expo (AIE), Booth 7A29, in Hamburg, Germany.
AvaSpire® PAEK provides greater toughness and reduced cost compared to standard polyetheretherketone (PEEK) for interior aerospace applications such as the structural end caps and anchors used in this design. The ultra-high performance polymer also offers greater strength, better creep resistance, and improved hydrolytic stability compared to nylon and other competitive engineering thermoplastics that were also considered, according to Jack DeRuyter, vice president of business development for Technifab. The unfilled AvaSpire® PAEK grade also meets the Federal Aviation Administration (FAA) Flammability, Smoke Density, and Toxic Gas Emission (FST) requirements.
The injection molded end caps made of AvaSpire® PAEK serve as part of a rigid connector system for the ducting. The 0.25 cm (0.10 in) thick end caps, which range in diameter from 5.1 to 15.2 cm (2 to 6-in), are attached to the ducting with an epoxy-based adhesive. AvaSpire® PAEK is also used to injection mold the anchors that serve as mounting brackets for the ducting. They have the same dimensions as the end caps and are also attached to the ducting with an adhesive.
Technifab's new ducting system is being installed on current airframes produced by major aircraft manufacturers.
AvaSpire® PAEK is a family of customizable high-performance polyketones tailored to fill cost and performance gaps between PEEK and other high-performance polymers. These materials are part of Solvay's Spire® Ultra Polymers portfolio, which includes KetaSpire® PEEK.
