Hexcel Corporation (NYSE: HXL), a global leader in advanced composites, has introduced a next-generation Type IV carbon overwrap pressure vessel (COPV), developed in collaboration with HyPerComp Engineering Inc. (HEI). The vessel is manufactured with Hexcel s high-performance HexTow IM11-R/12K carbon fiber and is designed for critical aerospace and space applications.

Hexcel s IM11-R/12K fiber enables the next generation of composite pressure vessels, delivering outstanding burst pressure performance and reliability, said Lyndon Smith, President, Americas & Global Fibers, Hexcel.

Type IV COPVs feature a polymer liner fully wrapped in continuous carbon fiber, offering corrosion resistance and substantial weight savings compared to traditional metal tanks. These vessels are ideal for storing hydrogen, helium, and nitrogen in demanding environments such as launch vehicles and space systems. The design ensures excellent processability during filament winding and high translation of fiber properties, meeting the rising demand for lightweight, high-strength pressure solutions.

We have a high level of collaboration with Hexcel, resulting in the development of COPVs for extreme environments. Initial testing has shown excellent fiber strength and burst pressure performance, said Jake Walker, Chief Innovation Officer at HyPerComp. The combination of Hexcel s fiber technology and our engineering expertise sets a high benchmark for future COPV qualification.

Hexcel and HyPerComp are advancing toward certification of these Type IV vessels, with applications expected to extend beyond aerospace into broader high-performance markets. The new vessel was showcased at CAMX 2025 in Orlando, Florida (booth F17) from September 9 11.
