Victrex PEEK Passes Tests after Exposure to Jet Fuel

14 June 2011

Amphenol have conducted tests on Victrex PEEK to prove its resistance to jet fuel.

According to Victrex, glass-filled Victrex PEEK polymer injection moulded P-clamps were not adversely affected after being submerged in aviation Jet fuel for twelve months at room temperature.

Jocelyn Belanger, Senior Design Engineer at Amphenol, stated, “The results showed that there were no visual signs of softening, swelling, or loss of adhesion in the over moulded fluorosilicone cushion in any of the submerged samples removed from the jet fuel. Each sample exposed to the jet fuel passed both cushion adhesion and cushion retention testing.” The ultimate strength of each P-clamp sample after jet fuel submersion was greater than the design ultimate load of 556N (125lbf), with the average ultimate load being 28% higher than the design load. “The ability of Victrex PEEK polymer to retain its properties after exposure to jet fuel confirmed that the polymer has the strength and chemical resistance to perform in the fuel tank environment where the P-clamps are used to hold wire harnesses and fuel and hydraulic hoses,” said Belanger.

As well as the ability to maintain its properties while withstanding extreme chemical environments, including jet fuels and hydraulic fluids mandatory requirements for aerospace polymers include light weight to lower fuel costs, excellent mechanical strength and dimensional stability, and the ability to meet industry standards and specifications regarding flame, smoke, and toxicity emissions. Victrex explain how their Victrex PEEK polymer is increasingly being specified since it meets these requirements, especially in metal replacement opportunities across multiple aircraft platforms allowing the design flexibility necessary for engineers to develop components and assemblies for the next generation of commercial aircraft, military aircraft, and advanced spacecraft.
