Amphenol picks VICTREX PEEK polymer for aircraft connector

The high performance thermoplastic has replaced the likes of stainless steel, titanium, and aluminum aboard aircraft for several decades, driven by industry demands for lighter solutions that allow for design simplification, standardization, and reduced overall costs.

This enables engineers to contribute to improving the fuel economy of an aircraft as well as helping to hit lean manufacturing goals at major airframe manufacturers.

Reducing the time it takes to install components is a key selling point for any newly designed aerospace part. “Victrex has always been very helpful in providing us with technical support over the years for various application developments.

Through both companies’ efforts, VICTREX PEEK polymer was able to give our engineering team the freedom and processing flexibility to simplify and consolidate parts when it came to designing and manufacturing the ground block,” said Tony Padula, Product Manager for Amphenol Pcd. “Instead of installing several metal retention clips separately, a one-piece VICTREX PEEK retention clip is used to make the process much easier and more efficient for the assembly teams.”

“With several hundred electrical connectors aboard each plane, potential fuel savings can also be quite significant,” said Harald Hedderich, Aerospace Strategic Marketing Manager for Victrex Polymer Solutions. “At a time when cost savings are extremely important to the aerospace industry, our polymers help deliver substantial weight reductions which ultimately lead to lower fuel consumption and CO2 emissions.”

Amphenol has also performed tests on VICTREX PEEK polymers to verify that it was a reliable material for various aerospace environments.

“For instance, we have tested the material in 70°C (158°F) hydraulic fluid for 1,000 hours and were pleased with the durability of the material,” explained Padula. “Proving that VICTREX PEEK could thrive in these harsh conditions gave us the confidence to specify this material in our designs.”

The thermoplastic connectors not only eliminate the need for anti-corrosion treatments, but are non-conductive as well, improving the electrical integrity of the connector. Electrical integrity is paramount as the ground block connectors are used to secure and fasten electrical wiring that is critical to the aircraft.
