Advanced composites company Hexcel Corp. (Stamford, CT) will showcase its newest additive manufacturing technology that combines high-performance PEKK thermoplastics with carbon fiber at the CAMX conference on Oct. 16 to 18 in Dallas TX. It is exhibiting in booth Y13.
The 3D-printed HexPEKK structures offer significant weight, cost and time-to-market reductions, replacing traditional cast or machined metallic parts in demanding aerospace, satellite and defense applications. Hexcel acquired the technology from Oxford Performance Materials in December 2017.
Hexcel also will present its HexShield thermal-management system, which provides high temperature resistance in aircraft engine nacelles. By inserting a thermally resistant material into honeycomb cells, Hexcel provides a core product with unique heat-shielding capabilities that allows for the potential reuse of material after a fire event.
Hexcel will also promote its Acousti-Cap broadband noise-reducing honeycomb that significantly improves acoustic absorption in aircraft engine nacelles—the acoustic liner is precisely tuned to engine operating conditions.
HexTow HM50, Hexcel’s newest high-modulus fiber, will be launched at the show. The material boasts high modulus and tensile strength, making it ideal for commercial and defense aircraft and engines. Hexcel’s unsized HexTow carbon fibers provide excellent bonding interfacial properties with thermoplastic matrices, said the company. Not only will visitors see HexTow carbon fibers being used in Hexcel’s own HexPEKK SLS additive manufactured parts, but also in a bike frame produced by Arevo, which was made using the FDM 3D-printing process.
Hexcel develops, manufactures and markets lightweight, high-performance structural materials including carbon fibers, specialty reinforcements, prepregs and other fiber-reinforced matrix materials, honeycombs, adhesives, engineered core and composite structures for use in commercial aerospace, space, defense and industrial applications.
