Introduction
HexWeb® Acousti-Cap® is an innovative sound-reducing honeycomb technology developed by Hexcel, designed to enhance acoustical performance in aircraft engines without adding structural weight. This technology has been recognized with the JEC Innovation Award.

Product Overview
HexWeb® Acousti-Cap® consists of a non-metallic permeable cap material embedded into a honeycomb core, forming an acoustic septum. This design allows for significant noise reduction during aircraft takeoff and landing, improving upon existing technologies that often require compromises between weight and noise reduction.

Benefits

• Lower landing fees at airports due to reduced noise levels.
• Increased fleet flexibility.
• Improved cabin comfort for passengers.
• Reduction in other acoustic treatments, leading to lower weight and cost.

Customization
Customers can specify flow resistance characteristics, core thickness, number of caps per cell, and insertion depth, allowing for a product tailored to specific acoustic requirements.

New Developments
In 2010, Hexcel introduced an aluminum version of Acousti-Cap® that offers similar noise reduction benefits with added cost savings. This version can withstand temperatures up to 175˚C/350˚F and is compatible with standard industry processing techniques.
