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.
Focused on optimizing traditional hand layup, nacelle and thrust reverser manufacturers cast an eye on future use of automation and closed molding.
There are numerous methods for fabricating composite components. Selection of a method for a particular part, therefore, will depend on the materials, the part design and end-use or application. Here's a guide to selection.
Yes, advanced forms are in development, but has the technology progressed enough to make the business case?
