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 fiberreinforced 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.
SIGRACOMP® components made from carbon fiber-reinforced plastic (CFRP) In challenging high-tech applications requiring high strength and stiffness combined with light weight, SIGRACOMP CFRP components are irre-placeable. CFRP is lighter than aluminum or steel and is also enormously durable. The material is used in many industries from medical technology and mechanical engineering through robotics and automation technology to measuring technology and optics.

Production process
SIGRACOMP® components made from carbon fiber-reinforced plasticThe ideal material for lightweight construction
Carbon fiber-reinforced plastics are materials consisting of several components: a base or carrier substance, known as the matrix, and a second reinforcing component, the carbon fiber, which is embedded in the matrix. This combination results in high-performance materials with exceptional properties.
The different production technologies for CFRP components:• Prepreg compression molding• Autoclave technology (vacuum bag process)• Winding methods• Lamination• Blowing methods• Preform production (aerospace)• Resin transfer molding (RTM)
Our SIGRACOMP CFRP components have excellent mechanical properties combined with light weight. As a result, they are used in many different industries.

c Tensile strength testing of carbon fibers
With their low density, CFRP composites are supreme in terms of specific tensile strength. They outperform glass fiber-reinforced plastic (GRP), aluminum, and even high tensile steel. For this reason, CFRP materials dominate modern lightweight construction in high-stress applications.
Carbon fiber-reinforced plastic – combination of special propertiesBy using different matrix materials and fiber types, the properties of CFRP can be varied. This enables them to be optimally tailored to component requirements.

7CArBon FIBer-reInForCeD pLASTIC
Commercial carbon fibers today can be classified into two basic groups: high tensile fibers (HT) and ultrahigh modulus fibers (UHM). HT fibers cover 80 % of the market.
Fiber-reinforced composites are anisotropic, i.e. their properties differ according to fiber orientation. Their physical properties, such as elastic modulus or strength, vary as a function of the fiber orientation angle.
The thermal expansion coefficient of SIGRACOMP CFRP components can be adjusted within a certain range, making it possible to achieve very low or even negative thermal expansion coeffi-cients. This is important for optical pre-cision instruments but also for all other components that have to be dimension-ally stable.
