Systems for producing extremely resilient lightweight composites with a polyurethane matrix
The use of fiber-reinforced composites often starts when the properties of conventional materials no longer meet the customer's requirements. Laminate is frequently used in three-layer sandwich constructions. Here the two facings are composed of a fiber composite material and are spaced apart by the core. Sandwich constructions have a high structural strength and stability, combined with light weight. The diverse possibilities provided by this PUR-CSM PREG sandwich technology can be divided into automotive and non-automotive applications. In automotive applications, products such as trunk floors, rear shelves, headliners and sunroof linings are in large-scale production on a global scale for virtually all OEMs. Berths and storage compartments in the driver cabs of trucks are made using PUR-CSM PREG sandwich technology. As the trend for lightweight constructions has been gaining considerable momentum in recent years, the first exterior parts have also been created using the groundbreaking sandwich technology. For example, the roof modules in the volume models Jeep® "Renegade“ and Smart® "Fortwo“ are made up of PREG parts.
