Make your application stronger, lighter and smarter Why sandwich composites? appropriate fibers, resin and core you can create a product that has, for example, high thermal insulation, tailored mechanical behavior and fire resistance. With sandwich composites you can: • Decrease weight and increase strength • fuel cost or increase payload Save • Reduce lifecycle cost • Lower your carbon footprint • Enjoy more design freedom Why a solution from Diab? The concept is cleverly simple. Two thin, strong and stiff materials are separated by a lightweight core. The result is a strong and durable...

What are the key benefits for your application? Optimize your products by tailoring the materials to your needs. Stronger Sandwich composites can be engineered to be stronger and more durable than traditional materials, such as aluminum, steel or wood. Lighter The high specific strength of sandwich composites makes them a logical choice for weight sensitive products, such as airplanes, boats and wind blades. Smarter Allowing for increased payload, reduced fuel consumption and lower carbon footprint, sandwich composites are the smart choice for a more sustainable world. Design...

You can have it all: A strong and light-weight material that allows you to create smarter solutions. With great design flexibility you can realize your wildest dreams. Create your product to your needs, with tailored materials featuring special properties such as FST resistance.

The basics of sandwich composites A typical sandwich consists of two skins or laminates with a thicker structural core in between. They are joined by resin or an adhesive. The sandwich principle A sandwich structure essentially works like an I-beam in 2D. When a sandwich panel is loaded in bending, the skins (flanges in an I-beam) carry in-plane compression and tension loads and the core (web in an I-beam) carries out-of-plane shear loads. The further the skins are separated, the stronger and stiffer the sandwich will be. The skins and the core are bonded with the same resin of the skins or...

The formability of sandwich composites allows for greater design freedom and precise aerodynamic shapes. The strength of an I-beam with the weight of a feather. Applications where weight is crucial, such as airplanes, benefit greatly from the high strength-to weight ratio.

Working together Sandwich composites offer a vast freedom of design and material combination. Together, we can find the optimal solution to your specific needs. Shape For curved shapes, the core can be either thermo-formed or supplied with cut patterns to allow it to easily form to the mold. To optimize weight and resin consumption or simplify the manufacturing process, Diab offers different cut patterns (finishing) dedicated to specific needs. For more information on finishing, download the Diab Finishing brochure at diabgroup.com. Manufacturing process There are many ways to produce...
