Carbon fiber acoustic arrays used in marine detection systems are made up of carbon fiber polymer, which is built into the design of the hydrophone. The hydrophone is a sensitive underwater microphone that is used to pick-up underwater sounds. The carbon fiber polymer is molded into a form that matches the shape of the hydrophone and is integrated with a layer of piezoelectric material. This material transforms the sound waves into electrical signals, enabling the detection system to recognize the source of the sound.

Carbon fiber acoustic arrays have several advantages over traditional metal-based systems. One of the primary benefits is their low weight. A carbon fiber array can be up to 75 percent lighter than a metal counterpart, making them ideal for use in remote locations or situations where weight is crucial, such as in a submarine. Furthermore, carbon fiber arrays have excellent noise cancellation properties, making them ideal for use in high-noise environments, such as areas with strong underwater currents.
