HiFlow™ is Hexcel’s new trademark for a family of next generation liquid resins for the manufacture of aerospace structures by liquid molding techniques such as vacuum infusion and resin transfer molding.
Responding to OEMs’ challenges for future primary structures, HiFlow™ resin systems used in conjunction with a new generation of HiTape® and HiMax™ structural dry reinforcements will enhance the overall performance of aerospace structures, enabling the further penetration of high performance composites in this industry.
The resin chemistry of the HiFlow™ range is based on a new proprietary technology relating to the hardeners that enhances the dry and hot/wet performance and eases processing.
HiFlow™ HF610 is the first resin of this new family to be launched, providing a potential long infusion window for large aerospace structures. The standard cure cycle for HiFlow™ HF610 includes a dwell plus 2 hours at 180°C.
