Hexcel (Stamford, CT, US) is featuring one of it newest technologies, HexAM additive manufacturing technology, which combines high-performance PEKK thermoplastics with carbon fiber to produce flight-ready 3D-printed HexPEKK parts. Hexcel acquired this technology from Oxford Performance Materials in December 2017. HexPEKK structures offer weight, cost and time-to-market reductions, replacing traditional cast or machined metallic parts in highly demanding aerospace, satellite and defense applications.

Hexcel also is presenting its HexShield thermal management system, which provides high-temperature resistance in aircraft engine nacelles. HexShield works by integrating a thermally resistant material into honeycomb cells, providing a core product with heat-shielding capabilities that allow for the potential re-use of material after a fire event.

Also in Hexcel’s booth is Acousti-Cap broadband noise-reducing honeycomb, designed to improve acoustic absorption in aircraft engine nacelles. The acoustic treatment can be positioned at a consistent depth and resistance within the core, or can be placed in a pattern of varying depths and/or resistances, offering an acoustic liner that is tuned to the engine operating conditions. Another Hexcel product at the show is the line of unsized HexTow carbon fibers for use with thermoplastic matrices; included is its newest high-modulus fiber, HexTow HM50, for commercial and defense aircraft and engines. Hexcel is promoting its latest PrimeTex woven carbon fabrics that decrease areal weight while providing a smooth, closed weave and uniform cosmetic appearance, and its HiMax multiaxial reinforcements.
