NAVY VESSELS

Next generation naval strength

Structural core materials for modern navy and defense vessels.

Naval operations demand more than strength—they require tactical advantage, durability, and speed. While steel has long been the standard in military shipbuilding, advanced composite solutions are becoming increasingly favored for their ability to reduce weight, enhance performance, and minimize detectability.

Diab’s structural core materials, together with the sandwich structure, offer clear benefits for both fast patrol craft and larger navy vessels. Their naturally low radar reflectivity helps reduce visibility, while their high strength-to-weight ratio supports speed, maneuverability, and operational efficiency. Our solutions are ideal for hulls, decks, bulkheads, floors, masts, transoms, engine beds, and interiors, where weight reduction and mechanical performance are equally critical.

Engineered for extreme conditions, Diab’s cores deliver excellent fatigue and chock resistance and slamming performance in sandwich structures. That makes them particularly suitable for high-speed, high-sea operations, such as those performed by patrol boats, coast guard vessels, and other naval platforms operating under pressure.

Closed-cell structures resist water absorption and offer strong chemical resistance, extending durability in challenging marine environments. The materials are easy to form and machine, providing flexibility in complex builds and clean, consistent surface finishes. A wide range of finishing options, combined with Diab’s advanced kitting services, simplifies manufacturing, reduces resin use, maximizes weight savings, and reduces carbon footprint.

The result is a lighter, more agile vessel that performs under pressure, with reduced fuel consumption, and a long service life even in the most demanding maritime settings.
