2. Corrosion Resistance FRP materials are inherently resistant to corrosion, which is a critical factor in drainage applications. Traditional metal channels can suffer from rust and degradation over time, particularly in environments rich in chemicals or moisture. In contrast, FRP drain channels maintain their integrity and performance, reducing maintenance requirements and lifecycle costs.

Another area where composite gratings shine is in the development of lasers and optical communication systems. By integrating composite gratings into laser cavities, engineers can achieve more stable and narrow linewidth outputs, enhancing the performance of laser systems. In optical communication, composite gratings are instrumental in dense wavelength division multiplexing (DWDM) technologies, where they help in multiplexing and demultiplexing multiple optical signals with minimal cross-talk and high precision.
