Non-metallic Flex-Core® HRH-302 Mid-Temperature honeycomb provides a critical bismaleimide (BMI) solution for the aerospace industry's evolving thermal management needs. 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 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.
