Hexcel is introducing its latest HexAM materials technology, HexPEKK EM – an electrically conductive, high-performance, PEKK-based thermoplastic carbon fiber composite additive manufacturing material offering industry-leading performance.
The move was to be expected given Hexcel’s leadership role in the composites market. The firm had acquired OPM’s PEKK SLS 3D printing technology to begin offering 3D printing service capabilities under the newly established HexAM brand. However in the beginning, HexAM focused exclusively on the unfilled PEKK powders originally developed by OPM. As EOS and Arkema moved to offer composite PEKK materials (HT-23) for SLS, it was logical to assume that Hexcel would also eventually move into this particularly interesting segment of AM.
The new HexPEKK EM material integrates advanced electromagnetic (EM) performance within complex 3D printed components for the commercial aerospace, defense, and military sectors. HexPEKK EM composite components are flight-ready after printing.
“The management of static electricity dissipation, electromagnetic interference, and radiation absorption is extremely important in the design of all air vehicles,” said Lawrence Varholak, Vice President of Additive Manufacturing at Hexcel, said. “The introduction of this advanced additive manufacturing material will enable the fabrication of extremely complex aerostructures with unparalleled structural and electrical functionality. It significantly reduces weight …
