Engines & Nacelles

Aircraft engines have evolved to include so many major composite components that carbon fiber epoxy prepregs account for typically half the volume of the entire nacelle structure.The next step for aero engine designers has been to apply composites technology to more complex structures within the engine itself. Hexcel’s proven sound attenuating treatment for our honeycomb core, called Acousti-Cap®, has been proven to quiet jet engine noise more effectively than any competing system and has been specified on the Boeing 787 and 737 MAX nacelles. Our unique capability to weave carbon on a 45-degree bias helps customers reduce scrap. Our toughest carbon fiber prepreg system is used for the front fan blade on the GEnx engine and our HexTow® carbon fiber is used on the LEAP Engine fan blades and casing.
