PEEK aerospace brackets for Bombardier aircraft drive down manufacturing costs


A new bracket technology suitable for use in hydraulic and fuel brackets for the wings, center box and fuel tanks of aircraft can reportedly result in significant weight reduction of at least 40% compared to metals. Enhancing the fuel economy of aircraft further, along with cost savings and streamlined manufacturing, has been a principal driver for the bracket manufacturer Denroy Plastics Ltd.

The UK-based precision plastics injection molding specialist developed the optimized brackets in close collaboration with Bombardier and polyetheretherketone (PEEK) supplier Victrex. Made of an electrostatically dissipative Victrex PEEK-ESD polymer, with proven performance in harsh environments including aggressive aerospace fluids, the bracket is specified in commercial aircraft such as Bombardier's C-Series, Global, and Learjet aircraft.
