Lighter structures for demanding naval environments

In marine defence, success depends on weight efficiency, durability and operational resilience. Diab provides lightweight foam core solutions that enhance structural performance and speed, while meeting the strict requirements of surface vessels, superstructures and autonomous platforms.

Marine applications require materials that maintain reliable long-term properties in harsh conditions. Diab develops foam core solutions engineered for low water uptake, hydrolysis resistance, UV stability and resistance to salt fog exposure, supporting dependable operation over time. Excellent shock absorption is another key characteristic of our core materials, particularly for mine countermeasure vessels.

Diab supports shipyards and system integrators with large-format core materials and precision-cut kits, including labelled components for efficient assembly, traceability and through-life support. Combined with expertise in sandwich composite structures and bonding technologies, this enables reliable qualification processes and lightweight, durable solutions for advanced naval structures.

Integrated insulation properties help manage both thermal and acoustic conditions, contributing to improved onboard environments and reduced noise signatures. Buoyancy characteristics support flotation and stability, while crash energy management and ballistic structural performance contribute to enhanced protection and durability in high-risk operational scenarios.

Platform applications

Our materials are used across a wide range of marine defence platforms, including mine hunting vessels and USVs, as well as vessel superstructures, supporting lighter, faster, safer and more efficient naval design.
