Hexcel HexPly: Revolutionizing Aircraft Engine Noise Reduction with HexWeb® Acousti-Cap®

Revolutionary Noise Reduction Technology

Hexcel's HexWeb® Acousti-Cap® sound attenuating honeycomb is a game-changer in the realm of aircraft engine design. This innovative product has received the prestigious JEC Innovation Award for its ability to enable superior acoustical performance, particularly in reducing noise levels during takeoff and landing, all without adding unnecessary structural weight. Unlike existing technologies that force tradeoffs between weight and noise reduction, HexWeb® Acousti-Cap® offers a groundbreaking solution that prioritizes both acoustical efficiency and structural integrity.

Cutting-Edge Engineering for Optimal Performance

HexWeb® Acousti-Cap® honeycomb is meticulously crafted with a non-metallic core embedded with permeable cap material, forming an acoustic septum. This specialized design allows customers to customize the flow resistance characteristics, core thickness, number of caps per cell, and insertion depth, resulting in a product that is finely tuned to their unique acoustic requirements. Renowned engine manufacturers like GE and Rolls-Royce utilize HexWeb® Acousti-Cap® to significantly reduce engine noise by up to 30%. Engines like the GENX-2B and LEAP, powered by this cutting-edge technology, have already showcased exceptional performance and noise reduction benefits.

Unparalleled Benefits for Aerospace Industry

The advantages of HexWeb® Acousti-Cap® honeycomb extend far beyond noise reduction. Aircraft engine designers and operators benefit from lower landing fees at airports due to reduced noise levels, leading to substantial cost savings over time. Furthermore, the implementation of this innovative solution ensures increased fleet flexibility, improved cabin comfort, and a reduction in the need for additional acoustic treatments, translating to lower overall weight and costs. Testimonials from industry leaders like AleniaAermacchi affirm the transformative impact of Hexcel's AcoustiCap® in creating state-of-the-art acoustic panels.

Aluminum Variant for Versatile Applications

In addition to its non-metallic counterpart, Hexcel offers an aluminum version of Acousti-Cap® honeycomb that provides comparable noise reduction performance across a broad spectrum. Launched in 2010, the aluminum variant is ideal for applications where thermal conductivity plays a crucial role. Capable of withstanding temperatures up to 350°F/175°C, this aluminum honeycomb is manufactured using industry-standard techniques for forming, joining, cutting, and machining. Its versatility and durability make it a preferred choice for demanding aerospace applications where performance and reliability are paramount.
