They are and comprehensive production, material, and used where other materials have reached their application know-how, we can offer our customers limits and are indispensable in many industries tailormade solutions for their requirements – today, e.g. for lightweight components with ultra- for example in automotive production, the wind high strength and stiffness. energy sector, and numerous other industrial applications. SGL Group is the only European manufacturer to material we produce ourselves via all intermediate SIGRAPREG prepregs made from carbon, glass, and aramid fibers steps to the finished end products. In this way, we can guarantee the highest product quality and SIGRAPREG woven, unidirectional, and multiaxial security of supply. fabric prepregs are state-of-the-art reinforcing cover the entire carbon fiber value chain: from raw materials. They are used in numerous industries, including automotive manufacturing, aerospace construction, the wind energy sector, mechanical engineering, medical technology, marine construction, sports equipment production, and antiballistic protection. b Prepreg production Video: From fiber to finished component sglgroup 4 Prepreg – a material with impressive all-round properties Q Excellent mechanical properties Q Low density Q Low thermal expansion Q Good electrical conductivity QNon-corrosive Q Own resin formulation for individual resin systems Q Precise laminate thickness tolerances Prepreg 5 SIGRAPREG® pre-impregnated materials made from carbon, glass, and aramid fibers SIGRAPREG is the brand name for textile reinforcing materials Automotive industry: Our prepregs are used in composites made from high-quality carbon, glass, and aramid fibers for applications such as lightweight car body and structural impregnated with different resin systems. components. For electric cars, entire passenger cells are produced from CFRP. The unidirectional, multiaxial, and woven fabric prepregs we supply are application-optimized high-performance materials. Wind energy: In wind farms, prepreg-reinforced plastics are Our prepregs are fatigue- and corrosion-resistant and have used for the rotor blades of wind turbines. excellent mechanical properties that make it possible to produce stiff, strong yet ultra-lightweight fiber-reinforced Aerospace: Prepreg-reinforced plastics are used for aircraft composites. We can tailor the prepregs perfectly to your components such as fuselage and wing structures, floor beams, requirements, since we formulate our own state-of-the-art and floor panels, and in space engineering for engine cowlings. resin systems and are equipped with many different production and processing options for reinforcing materials. Sports industry: In the sports sector, carbon fiber prepregreinforced composites are used as a high-performance material SIGRAPREG covers the whole range of carbon, glass, and for racing bike frames, racing car monocoques or golf clubs, aramid fiber materials. So we can offer a comprehensive fishing rods, and archery bows. portfolio capable of meeting the most diverse challenges. Mechanical engineering: Prepregs impart high strength and Typical applications include: stiffness and good damping properties to components subject to extreme dynamic stresses.

Prepreg 9 TowPregs based on fiber tows The TowPregs made by SGL Group are pre-impregnated carbon, glass, and aramid fiber bundles. Their resin content ranges from 26 to 40 %. The fibers, resin, tack, and TowPreg width can be varied to suit individual customer requirements and produced with very high consistency. We can develop application-optimized material perfectly tailored to our customers’ processes. Our TowPregs neither need any carrier paper nor foil. This saves our customers time and money, while also offering benefits in terms of environmental protection and health & safety. Liquid resin and solvents are no longer required in the production process. This has advantages for EHS management. In addition: • Equipment such as resin baths, mixers, and filling stations is no longer necessary, which cuts capital costs. • Resources are conserved and costs saved in material use because unusable resin residues are no longer generated. • The amount of plant cleaning is reduced, which makes processes simpler and more efficient. c SIGRAPREG TowPreg • Winding processes are speeded up, so plant productivity increases. • Stabile storage at room temperature With TowPregs from SGL Group, better results for Typical applications include: challenging processes can be achieved. • Pressurized containers Our TowPregs not only give components very good mechanical • Automotive components properties. They also have excellent winding behavior that • Leaf springs permits far more uniform placement to the highest accuracy, • Marine masts provides constant width and therefore excellent processing • Sports articles behaviour. 10 A comprehensive range of application-optimized, high-performance solutions.
