NASA's National Aeronautics and Space Administration (NASA) is seeking to procure Zylon Poly-Benzobisoxazole (PBO) Yarn, specifically 105 kg of 278 dtex AS-13 and 20 kg of 1110 dtex AS-13, for its Hypersonic Inflatable Aerodynamic Decelerator (HIAD) technology. This specialized material is crucial for meeting atmospheric reentry flight requirements for current and future NASA missions, particularly for use in inflatable aeroshells that aid in deceleration and flight control during descent. The procurement will be conducted as a sole source contract with TEIJIN FRONTIER (U.S.A.), INC., as they are the only provider of the required yarn, and interested organizations may submit their capabilities by January 12, 2026, to determine if competitive procurement is feasible. For further inquiries, interested parties can contact Laura Quave at laura.a.quave@nasa.gov or call 228-813-6420.
