Thermoplastic resin HexFlow®

for composites

As an industry innovator Hexcel has optimized its knowledge of resins and reinforcements to develop new solutions for faster, more cost-effective ways of manufacturing high performance composite parts. Resin Transfer Molding (RTM) and Vacuum Infusion are composite manufacturing methods that are particularly suitable for low- to medium-volume production rates, allowing high quality components to be created without using autoclaves. Large complex shapes can be achieved with good surface quality and a reduce part count. HexFlow® RTM6 is the aerospace industry standard for resin transfer molding, manufactured in Europe and the U.S. and qualified by all major OEMs and Tier 1s. This mono-component resin system has 20 years of proven service and is favoured for its high glass transition temperatures and flexibility in injection and cure cycle parameters. Also available is HexFlow® RTM651 - a premixed bismaleimide system for service temperatures to 232°C (450°F). Hexcel also offers a VaRTM resin systems VRM37 - targeted at secondary and primary aerospace structures. HexFlow® resins are fully compatible with the extensive range of HexForce® reinforcement fabrics. Our Technical Support Engineers are on hand to assist you with the optimum resin and reinforcement selection. Infusion is a cost-effective way of manufacturing aerospace parts without the investment in autoclave equipment.
