Hexion self-extinguishing epoxy resin
Hexion has introduced Epon FlameX, a halogen-free, non-particulate, non-additive chemistry for epoxies that provides strong fire/smoke/toxicity (FST) performance in aerospace applications.
Hexion (Columbus, OH, US) has introduced Epon FlameX, a halogen-free, non-particulate, non-additive chemistry for epoxies that provides strong fire/smoke/toxicity (FST) performance in aerospace, rail and marine interiors applications. It’s comprised of EPON FlameX Resin 9600 cured with EPIKURE FlameX Curing Agent 9700. This self-extinguishing resin meets the following standards: 60s vertical burn FAR25.853(a); smoke toxicity BSS7239; smoke density BSS7238. Epon FlameX can be used with resin transfer molding (RTM), infusion, filament winding and prepreg-based processes. It cures at 150°C and offers glass transition temperatures of 100°C (entry level), 130°C (intermediate level) and 190°C (advanced).
This technology was on display at SAMPE 2018.
Yes, advanced forms are in development, but has the technology progressed enough to make the business case?
The matrix binds the fiber reinforcement, gives the composite component its shape and determines its surface quality. A composite matrix may be a polymer, ceramic, metal or carbon. Here’s a guide to selection.
Approaching rollout and first flight, the 787 relies on innovations in composite materials and processes to hit its targets
