We develop and manufacture a series of lightweight components based on composite materials for modern vehicles. Our composite portfolio covers structural parts (e. g. roof frame, A, B and C pillar reinforcements, rear seats) and body parts (e. g. hood, doors, rear spoiler), powertrain and chassis system parts (e. g. leaf springs made of glass fiber reinforced plastic) and carbon ceramic high-performance brake discs.
In addition, our specialty graphite solutions reduce CO2 emissions and increase efficiency in vehicles with spare drives and standard internal combustion engines. Applications include bearings for other cooling water pumps and exhaust gas management, rotors and vanes for vacuum pumps or sealing rings for sealing.
In addition, we also provide SIGRACET gas diffusion layers for PEM fuel cells to achieve local zero-emission transportation.
Aerospace
Materials and components used in aerospace applications must ensure reliability and safety under extreme conditions. In addition to high strength and rigidity, strict fire resistance is also essential.
In addition, fuel consumption must be reduced through lightweight design, which is an important prerequisite for sustainable and economical air transportation. Carbon fiber reinforced composites can meet these requirements. Our products include fibers and materials as well as finished components, covering the entire value chain. Whether it is primary and secondary structures, subsystems or internal accessories, we can provide the right solution
energy storage
Energy storage is an important topic for sustainable transport and energy supply.
Sigma Carbon offers a variety of solutions for energy storage development based on specialty graphite. Our use of synthetic graphite as a negative electrode material makes an important contribution to improving the performance of lithium-ion batteries, while battery mats and bipolar plates in stationary energy storage devices (I. e. redox flow batteries) enable efficient charging and discharging. In addition, Sigma Carbon's specialty graphite solutions enable fast charging of lead-acid batteries
Wind energy
People's demand for energy is getting higher and higher, and in pursuit of higher cost efficiency (energy cost), the rotor diameter of wind turbines under construction or planning is getting larger and larger. Blades having a length of more than 80 meters have emerged, and plans are under way to manufacture blades having a length of more than 100 meters. Today's wind turbines are diverse, and our carbon fiber-based composites make an important contribution to their manufacture. These materials have the characteristics of high strength, high stiffness and low density, and can be used to manufacture highly efficient elongated rotor blade structures with aerodynamic efficiency, which have sufficient stiffness to withstand extreme stresses. Our innovative specialty products enable a new generation of rotor blades that set new standards for performance efficiency, service life and rotor dynamics. Our product range includes carbon fiber and semi-finished products based on glass and carbon fiber, which are specifically used in the production of rotor blades. We also develop customized solutions for carbon brushes, an important feature in wind turbines.
compound semiconductor and light emitting diode
Light-emitting diodes are colorful, not only illuminating our daily lives, but also efficient and energy-saving. The light emitting diode generates light through the semiconductor connection. Their performance depends to a large extent on the quality of these semiconductors.
This is where our special graphites come in: Isostatic graphite is the basis for the production of composite semiconductor layers. The compound semiconductor layer is produced in a "hot zone" at extreme temperatures in a so-called epitaxial or MOCVD process. The rotating carrier on which the wafers are coated in the reactor consists of isostatic graphite with a silicon carbide coating. Only this very pure homogeneous graphite can meet the high requirements of the coating process.
Semiconductor
Modern life is inseparable from semiconductors: computers, power supplies, light-emitting diodes, the Internet, and solar cells must work through semiconductors (such as silicon). In the various processes of semiconductor production, components made of special graphite are indispensable.
This applies to crystal growth or subsequent epitaxial or ion implantation surface treatment. These processes are carried out at very high temperatures and in an extremely corrosive environment. At the same time, these processes require the highest levels of purity and absolute precision. We offer graphite-based solutions covering the entire semiconductor production process and are one of the leading suppliers to the semiconductor industry with silicon carbide coating technology.
