Diab

The key to success in the marine industry is maximizing performance while minimizing weight, cost, and environmental impact. Our high-performance, structural core materials provide the highest strength-to-weight ratios for all marine applications, enabling higher speeds, longer ranges, greater payload capacities, and reduced power demands.

Their excellent fatigue and slamming properties also make them particularly suitable for special crafts that often operate in high-sea conditions. With the help of our technical expertise, structural engineering services, and application training, along with fossil-free Advanced kits that maximize weight savings and reduce carbon footprint, you can achieve maximum performance and cost efficiency.

MOTOR BOATS AND YACHTS

Structural core materials for high-performance motorboat design.

Whether designed for speed, sport, or everyday leisure, modern motorboats benefit from lightweight composite construction. Diab’s structural core materials enable weight reduction without compromising strength, thereby improving performance, fuel efficiency, and onboard comfort.

From hulls and decks to engine beds, transoms, interiors, bulkheads, and superstructures, our materials provide the stiffness and durability needed to handle high loads and challenging conditions. Their excellent fatigue resistance, low resin uptake, and special grades with prepreg compatibility enable efficient, high-quality manufacturing.

Thanks to their closed-cell structure, Diab’s cores resist water absorption, while their impact resistance, damage tolerance, and high repairability help extend service life even in demanding marine environments.

Our materials are also highly formable and easy to machine, making it easier to build complex shapes with consistent surface quality and clean finishes. A wide range of available finishes offers design freedom and process efficiency for everything from custom builds to series production.

Diab also offers advanced kitting solutions for streamlined production, improved accuracy, maximized weight savings, and reduced carbon footprint. The result is a lighter, more efficient, and sustainable craft with reduced fuel consumption, improved performance, and long-term durability.

SAILBOATS

Lightweight, high-performance core materials for modern sailing yachts.

Whether designed for racing or leisure, sailing boats benefit greatly from lightweight, high-performance composite structures. By reducing weight while maintaining strength and stiffness, Diab’s structural core materials help optimize everything from hulls and decks to keels, bulkheads, interiors, and rudders.

With excellent fatigue resistance and impact durability, our materials are engineered to perform under the unique demands of marine environments. Their closed-cell structure resists water absorption, while low resin uptake and special grades with prepreg compatibility enable efficient and reliable production.

Diab’s cores are also highly formable and easy to machine, allowing for smooth integration across complex shapes and delivering clean surface finishes. This design flexibility is complemented by a wide range of finish options, allowing builders to achieve both performance and aesthetic control.

To simplify manufacturing, Diab offers advanced kitting services that ensure every part fits precisely in the mould. This saves time at the yard and reduces material waste, maximizes weight savings and resin use, and consequently lowers the carbon footprint.

Whether your focus is speed, comfort, sustainability, or all three, Diab provides the core solutions to help you deliver the next generation of sailing yachts.
