3 BUSINESS UNIT COMPOSITEs Fibers and MATERIALS 3 Unique integrated value chain SGL Group covers the complete value chain of carbon fiber products: from precursor via carbon fibers, fabrics, and prepregs to the finished CFRP components. Our carbon fibers produced by SGL Group in Europe and North America form the basis for all processing steps in fiberreinforced composite applications. Carbon fiber-reinforced plastics are high-performance materials with unique properties. They are used where other materials have reached their limits and are indispensable in many industries today, e.g. for lightweight components with ultrahigh strength and stiffness. SGL Group is the only European manufacturer to cover the entire carbon fiber value chain: from raw material we produce ourselves via all intermediate steps to the finished end products. In this way, we can guarantee the highest product quality and security of supply. With many different processing technologies and comprehensive production, material, and application know-how, we can offer our customers tailormade solutions for their requirements for example in automotive production, the wind energy sector, and numerous other industrial applications. SIGRAPREG prepregs made from carbon, glass, and aramid fibers SIGRAPREG woven, unidirectional, and multiaxial fabric prepregs are state-of-the-art reinforcing 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

5 Prepreg 5 SIGRAPREG pre-impregnated materials made from carbon, glass, and aramid fibers SIGRAPREG is the brand name for textile reinforcing materials made from high-quality carbon, glass, and aramid fibers impregnated with different resin systems. The unidirectional, multiaxial, and woven fabric prepregs we supply are application-optimized high-performance materials. Our prepregs are fatigue- and corrosion-resistant and have excellent mechanical properties that make it possible to produce stiff, strong yet ultra-lightweight fiber-reinforced composites. We can tailor the prepregs perfectly to your requirements, since we formulate our own state-of-the-art resin systems and are equipped with many different production and processing options for reinforcing materials. SIGRAPREG covers the whole range of carbon, glass, and aramid fiber materials. So we can offer a comprehensive portfolio capable of meeting the most diverse challenges. Typical applications include: Automotive industry: Our prepregs are used in composites for applications such as lightweight car body and structural components. For electric cars, entire passenger cells are produced from CFRP. Wind energy: In wind farms, prepreg-reinforced plastics are used for the rotor blades of wind turbines. Aerospace: Prepreg-reinforced plastics are used for aircraft components such as fuselage and wing structures, floor beams, and floor panels, and in space engineering for engine cowlings. Sports industry: In the sports sector, carbon fiber prepregreinforced composites are used as a high-performance material for racing bike frames, racing car monocoques or golf clubs, fishing rods, and archery bows. Mechanical engineering: Prepregs impart high strength and stiffness and good damping properties to components subject to extreme dynamic stresses. Typical applications include gripper bars or lifting beams and transfer bars for automation technology. b SIGRAPREG unidirectional carbon fabric Antiballistic protection: Pre-impregnated hybrid and aramid fabrics are used particularly for safety helmets and vehicle armor.

6 6 The best resin system for each application The prepregs made by SGL Group are the result of advanced product development. We combine high-quality resin systems formulated in-house with state-of-the-art reinforcing materials. Our range includes a wide variety of resin systems with different glass transition points (Tg), curing temperatures, viscosity, tack, and storage stability. This enables us to supply materials with maximum performance and minimum weight that are optimally tailored to your specific application. c Resin application for impregnation Nomenclature key SIGRAPREG C W95-PL1/1-E331/48% Brand name SIGRAPREG 2 Material C = carbon G = glass A = aramid H = hybrid 3 Type W = woven fabric U = unidirectional B = biaxial T = triaxial Q = quadriaxial Individual resin systems for different requirements 4 Areal weight in g/m2 5 Weave / fiber orientation / fixation woven PL 1/1 = plain TW 2/2 = twill 2/2 TW 4/4 = twill 4/4 multiaxial 0 = = 0 /90 45 = -45 / = 0 /-45 / = 0 /-45 / 90 /+45 6 Resin type Exxx = epoxy Pxxx = phenolic NF = no fixation SO = scrim one-sided SD = scrim double-sided ST = stitched 7 Resin content in % Resin system Type Tg [ C] Curing temperature [ C] Shelf life at RT (20 C) days Shelf life at -18 C months Tack Impact modification E500 E501 E502 E503 epoxy M yes E300 E301 epoxy L/M/H yes E400 E402 epoxy L no E310 E311 epoxy L/M/H yes E320 E321 E322 E323 epoxy M yes E450 transp. epoxy M no E700 epoxy M yes E302 epoxy L/M/H no E340 epoxy L/M no E330 epoxy L/M/H yes E800 epoxy L/M/H no P320 P321 P322 phenolic > M/H no P310 phenolic L/M/H P500 phenolic L/M/H Other resin systems available on request.

9 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. Winding processes are speeded up, so plant productivity increases. Stabile storage at room temperature c SIGRAPREG TowPreg With TowPregs from SGL Group, better results for challenging processes can be achieved. Our TowPregs not only give components very good mechanical properties. They also have excellent winding behavior that permits far more uniform placement to the highest accuracy, provides constant width and therefore excellent processing behaviour. Typical applications include: Pressurized containers Automotive components Leaf springs Marine masts Sports articles
