Hexcel Corporation

Founded in 1948, Hexcel designs and manufactures a range of highly engineered composite fibers, fabrics, resins, and structures for use in the commercial aerospace, defense, and high-performance automotive markets. These are lighter than metal and perform under rigorous conditions in aircraft frames, wings, engines, and other components and subassemblies. The company's name derives from the six-sided honeycomb structures that lend many of its products their light weight and rigidity. Hexcel's biggest customers are Airbus (40% of 2024 sales) and Boeing (15% of 2024 sales; 25% before the pandemic) and their respective subcontractors.
