Hexcel stays a generation ahead with new Flex-Core® HRH-302 mid-temperature Honeycomb Core
Hexcel Corporation announced the launch of its new non-metallic Flex-Core® HRH-302 Mid-Temperature Honeycomb product. This innovative material provides a critical bismaleimide (BMI) solution for the aerospace industry’s evolving thermal management needs.
“HRH-302 represents our commitment to staying a generation ahead and delivering products that meet the demands of our customers,” said Bobby Rowe, Vice President, Product Management, Core & Engineered Products at Hexcel. “This new mid-temperature honeycomb offers a unique balance of performance and cost, making it a game-changer for both commercial and military applications.”
The Flex-Core® HRH-302 is designed to sustain service temperatures up to 450°F, bridging the gap between traditional phenolic-based materials and high-cost polyamide solutions. Leveraging the expertise Hexcel has in thermoplastic resins, the product offers improved thermal capabilities while maintaining similar mechanical properties to existing honeycomb materials.
“The flexibility and thermal performance of HRH-302 make it ideally suited for the complex curvatures and increasing heat loads found in next-generation aircraft nacelles,” added Rowe. “We’re excited to work closely with our customers to demonstrate the benefits of this new material on critical military and commercial programs.”
Flex-Core® HRH-302 is currently undergoing testing and certification with leading aerospace original equipment manufacturers (OEMs). The product is expected to be a key enabler for future engine designs, as well as emerging applications in the urban air mobility market, where lightweight, heat-managing materials are in high demand.
