Hexcel’s HexPEKK EM Offers Electromagnetic Shielding, Radar Absorption
Composite components are flight-ready after printing, omitting the need for costly and time-consuming secondary processing steps.
HexPEKK EM composite components are flight-ready after printing, omitting the need for costly, time-consuming secondary processing steps.
Hexcel’s HexPEKK EM is an electrically conductive, high-performance, PEKK-based thermoplastic carbon fiber composite additive manufacturing (AM) material that integrates advanced electromagnetic (EM) performance within complex 3D-printed components for the commercial aerospace, defense and military sectors.
The company says that HexPEKK EM composite components are flight-ready after printing. Formulated specifically to meet the static electricity management, electromagnetic shielding and radiation absorption requirements of advanced aircraft applications, the PEKK carbon-fiber-blended material delivers unique electrical performance. Manufactured using the aerospace industry-qualified HexAM process, HexPEKK EM components are said to exhibit best-in-class environmental, operational temperature and chemical-resistant performance attainable in the aerospace industry.
By integrating this enhanced EM performance into AM components, HexPEKK EM parts do not require costly and time-consuming secondary processing steps, such as the application of conductive coating for the management of electromagnetic interference or radiation absorption. Target applications for HexPEKK EM cover a broad range of products, including exterior surfaces, leading edges, air inlets, electronic enclosures and cockpit structures for commercial airplanes, military aircraft, helicopters and UAV components.
According to engineers with GE Aviation, the challenges of additive metal manufacturing—serious as they are—are small compared to the promise that this technology holds. How else can you make a plane engine 1,000 pounds lighter?
The WAAM system has demonstrated the ability to produce a titanium aircraft part, but titanium in particular requires protection against oxidation.
A team of engineers turns to additive design to create—and successfully test—“the holy grail of the spaceship movement.”
