On December 19th, Boeing announced the launch of its Flex-Core subsidiary ® HRH-302 honeycomb core material products undergo performance testing. This product is expected to be applied to the coating structure of the exhaust nozzle of the US Navy MQ-25 unmanned refueling aircraft engine.
The MQ-25 is a carrier based unmanned refueling aircraft launched by Boeing, used to enhance the combat radius of carrier based fighters such as the Super Hornet, Growler, F-35C, and electronic jamming aircraft.
The use of composite materials not only reduces the weight of aircraft, but also enhances their durability and improves their payload, "said Bobby Rowe, Vice President of Composite Core Engineering Products." Aircraft are able to carry more fuel, sensors, communication equipment, and other devices for mission execution. This is crucial for aircraft carrier fleets operating in the vast Pacific Ocean.
In recent years, we have worked closely with Boeing in the field of composite materials to develop honeycomb core products that are lightweight, low-cost, have short production cycles, and meet aircraft performance requirements.
Flex-Core ® HRH-302 honeycomb core material is a product launched in early 2024, with an operating temperature of up to 450 degrees Fahrenheit (approximately 232 degrees Celsius), filling the gap between traditional phenolic based materials and high cost polyamide based materials. With the company's expertise in thermoplastic resins, this material further enhances the thermal performance of the product while maintaining the same mechanical properties as honeycomb core materials.
