The high-performance composites are not only lighter than these metals, they also outperform them. They can also achieve substantial weight advantages over lightweight metals, including TA6V titanium, 7075-T6 aluminium or ZK60A-T5 magnesium. Specifically, composites made from Victrex high-performance thermoplastics are up to 60% lighter than AISI 4130 steel, a tough chromium-nickel-molybdenum alloy widely used in aviation applications. This innovative approach can deliver weight savings of up to 60% over conventional metallic solutions, contributing to cuts in fuel consumption and thus emissions, delivering both cost and environmental benefits, while offering continuous manufacturing processes and cycle times measured in minutes rather than hours for thermoset alternatives. VICTREX AE 250 unidirectional prepreg tape is compatible with a range of lay-up and consolidation techniques, including automated fibre placement (AFP), and oven and press consolidation. In contrast the VICTREX AE 250 composites have a melting temperature of 305☌ and can be processed at between 340☌-360☌, allowing composite parts to be manufactured faster and more cheaply, using fast automated lay-up, out of autoclave processing, hot stamping and injection over-moulding – to also deliver added functionality.Īdditive manufactured PAEK demonstration bracket filament fusion (left) laser sinter (right) The combination of an innovative VICTREX PAEK polymer and reinforcing carbon fibres offers mechanical properties that are consistent with the requirements for structural aerospace applications, and VICTREX AE 250 thermoplastic composite solutions demonstrate how PAEK thermoplastic polymers continue to be an active source of innovation – 40 years after the invention of PEEK.Ĭomposites based on traditional PAEK polymers, such as PEEK and related polymers, need to be processed at temperatures in the range of 360☌-400☌. A typical VICTREX AE 250 thermoplastic composite part such as a structural bracket can reduce manufacturing time by 20-30% compared to metals or other polymer materials and it can reduce costs by up to 40% compared to machined metals. Thermoplastic composites offer multiple advantages, including very short production times and low overall costs, compared to their thermoset counterparts, which today are in frequent use. Meeting this kind of escalating demand clearly calls for new approaches and new technologies, and as a consequence, thermoplastic composites are expected to play an increasingly important role in accelerating future aircraft construction. The aircraft industry has forecast that approximately 41,000 new and replacement planes will be required by 2035. On the 40th anniversary of PEEK's creation, the relatively young thermoplastic is being increasingly deployed in aerospace-related thermoplastic composite solutions. COMAC is using VICTREX PIPES instead of metal pipes to protect high-voltage cables in its first commercial aircraft, the C919. ![]() for thermal acoustic blankets, brackets or pipes.Īirbus, for example, has used the thermoplastic for a primary structural component in the door of the A350 XWB to improve quality and reduce weight and costs by 40%. Today, more than 20,000 aircraft rely on VICTREX PAEK and PEEK based solutions, e.g. PEEK was soon recognised as a new polymer of enormous potential, and its commercialisation was then undertaken by Victrex. In 1978, ICI invented PEEK (polyetheretherketone), a member of the PAEK (polyaryletherketone) family of high-performance polymers.
