Hexcel Corp. (Stamford, Conn., U.S.) has been approved by Boeing (Chicago, Ill., U.S.) to produce HexPEKK-100 aerospace structures for major commercial aircraft platforms.

After review of Hexcel’s proprietary polyetherketoneketone (PEKK) and carbon fiber material formulation, Hexcel’s  HexPEKK-100 end-use components and HexAM additive manufacturing process, which uses selective laser sintering, can be obtained through Boeing’s Qualified Provider List (QPL). Hexcel says these HexPEKK components will be manufactured-to-print for commercial aerospace applications where complexity, weight reduction and strong mechanical performance are critical.

HexPEKK-100 parts are said to meet interior aircraft smoke and toxicity requirements and are suitable for complex components such as optimized brackets, environmental control system ducts and castings.
