SGL Carbon

SGL Carbon (SGL Carbon SE) is a specialist manufacturer of carbon-based materials and composite solutions, operating as a Tier 2 and Tier 3 supplier within the aerospace value chain. The company manages the entire production cycle from precursor chemicals and carbon fibres to finished composite components and textile semi-finished products. Its primary role in the sector involves the supply of high-strength, low-weight materials used to replace metallic structures in airframes and cabin interiors. The organisation maintains long-term supply agreements with major original equipment manufacturers and Tier 1 suppliers, notably supporting the Airbus A350 XWB and A320 programmes through the provision of carbon fibre materials and reinforced plastics. They have also partnered with Brembo for braking systems and supplied composite materials for Boeing platforms and regional jet programmes. Their products are integrated into primary structures, flight control surfaces, and interior linings where weight reduction is critical for fuel efficiency. Prospective buyers should verify the specific material certifications relevant to their jurisdiction, such as Nadcap accreditation for composite manufacturing and AS9100 quality management standards. It is essential to confirm the production capacity of specific European or North American sites relative to project volume, as lead times for carbon fibre precursors can fluctuate based on global demand. Partners should also assess the company’s current focus on thermoplastic versus thermoset resins depending on their specific assembly requirements.
