Unique integrated value chainSGL 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 fiber-reinforced composite applications.

Carbon fiber-reinforced plastics are high-perfor-mance 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 ultra-high 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 pre-impregnated materials made from carbon, glass, and aramid fibers SIGRAPREG woven, non-woven, unidirectional, and multiaxial fabric prepregs as well as our TowPregs and adhesive films 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 construc-tion, sports equipment production, and antiballistic protection.

SIGRAPREG is the brand name for textile reinforcing materials made from high-quality carbon, glass, and aramid fibers impregnated with different resin systems.

The woven, non-woven, unidirectional, and multiaxial fabric prepregs as well as the TowPregs and adhesive films we supply are application-optimized high-performance materials. Our pre-impregnated materials are fatigue- and corrosion-resistant and have excellent mechanical properties that make it possible to produce stiff, strong yet ultra-lightweight f�ber-reinforced composites. We can tailor the pre-impregnated products 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 pre-impregnated materials 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, pre-impregnated materials are used for the rotor blades of wind turbines.

Aerospace: Pre-impregnated materials 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, composites reinforced with pre-impregnated materials are used as a high-perfor-mance material for racing bike frames, racing car monocoques or golf clubs, fishing rods, and archery bows.

Mechanical engineering: Pre-impregnated materials 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.

Antiballistic protection: Pre-impregnated hybrid and aramid fabrics are used particularly for safety helmets and vehicle armor.

We produce the woven fabrics for our SIGRAPREG prepregs in our own weaving facility. We use 1k, 3k, 6k, 12k or 24k carbon fiber tow as the material basis. In hybrid woven fabrics, we also process glass and aramid fibers.

SIGRAPREG non-woven prepregs base on our 50k carbon fiber. They are characterized by isotropic properties, the even distribution of the fiber.

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.

SIGRAPREG TowPregs offer processing advantages over wet filament winding. This saves our customers time and money, while also offering benefits in terms of environmental protection and health & safety.

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 winding to the highest accuracy.Even for challenging fiber placement processes, our SIGRAPREG TowPregs are optimally suited. This is primarily a result of their constant width and easy processability.

Typical applications include:• Pressurized containers • Marine masts• Automotive components • Sports articles• Leaf springs
