Victrex AE250

PAEK Composites for the Aerospace Industry

The global PAEK-based solutions provider, Victrex, Thornton Cleveleys, UK, is launching composites for the aerospace industry in the form of unidirectional (UD) tape and laminate panels. Introduced under the brand “Victrex AE250 composites”, the new product group enables the production of continuously-reinforced components that can perform under load.

The Victrex AE250 product family has been designed for aerospace applications (figure: Victrex)

Such components include brackets, clips, clamps, and housings used throughout the aircraft in primary and secondary structures. The development and launch builds on the hybrid molding technology released in 2014 and also serves as proof that Victrex is moving forward in the supply chain to provide enhanced solutions.

Victrex AE250 composites have shown weight savings of up to 60 % under certain circumstances when compared to metals such as aluminum, stainless steel and titanium. That weight reduction translates directly into significant gains in fuel-efficiency and reduced CO2 emissions. The composites have also shown an up to 5x higher specific strength compared to those of metals.

With Victrex AE250 composites being used as inserts in existing injection molding equipment, the hybrid molding process enables the overmolding of a continuously-reinforced thermoplastic composite with Victrex PEEK injection molding polymers. The hybrid molding technology offers major advantages, including improved cycle times, lower energy requirements, and the elimination of scrap and secondary operations. These factors help to reduce total system cost, a high priority in the industry's effort to move planes off the assembly line faster and more cost-effectively.

Compared to thermoset solutions, PAEK composites can be processed faster, using out-of-autoclave methods, and are 100% recyclable. They have better damage tolerance than thermosets and offer greater chemical resistance, fatigue performance and FST (flame/smoke/toxicity) properties, while matching the strength and stiffness of thermosets. In comparison to metals, corrosion resistance, processing speed and thermal insulation are improved, while impact resistance and damage tolerance will be similar.

The key features of the Victrex AE250 composites also include outstanding high-temperature performance and thermal stability, a wide-ranging chemical resistance to aerospace fluids and gases, and excellent resistance to hydrolysis and corrosion.
