Propulsion & Systems
Full speed ahead for composite aircraft engines
Air mobility and space travel are evolving at a fast-pace, requiring lighter but yet safe propulsion technology. Solvay’s resins, adhesives and composites materials applications for aircraft engines create lightweight propeller parts that withstand high temperatures and impacts. We are proud to supply the advanced structural composites used on Safran's LEAP engine, which is manufactured by CFM International and used on Airbus, Boeing and Comac single-aisle aircraft.
Lighter and more heat-resistant propulsion technology
By replacing titanium engine parts with composite materials, the weight can be reduced by 50% and achieve performance in high-temperatures. Clients can rely on a vast product offering which includes lightweight applications for:
Engines: epoxy, bismaleimide (BMI), and polyimide resins to retain high-performance properties for excellent adhesion, chemical and heat resistance, as well as mechanical and electrical insulating properties.
Last but not least, BMI resins allow for the highest translation of fiber properties in tension and compression loading—CYCOM 5250-4 offers 350F to 500F service temperature capability while providing excellent damage tolerance. BMI-based aerospace components have been in service for over 20 years with excellent maintenance, repair, and overhaul performance.
WHAT CUSTOMERS SAY
Solvay has been a long term trusted supplier of Safran, supplying advanced composite materials on several engine and nacelle programs. The cooperation on the LEAP program reinforces the relationship between the two groups on a larger portfolio.
