NEWS 25 CompositesWorld.com SAMPE Exhibitors Target Next-Gen Aircraft says that many OEMs are in the process of determining suitable applications for this technology. • Hexion (Columbus, OH, US) introduced Epon FlameX, a halogen-free, nonparticulate, nonadditive chemistry for epoxies that provides strong fire/smoke/toxicity (FST) performance in aerospace, rail and marine interiors applications. It comprises EPON FlameX Resin 9600 cured with EPIKURE FlameX Curing Agent 9700. This self-extinguishing resin meets the following standards: 60-second vertical burn (FAR25.853(a)); smoke toxic- ity (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). • American GFM (Chesapeake, VA, US) featured in its booth US120/CM10, a highly automated, three-zone marking/cutting/offloading ply-cutting and kitting system. It features an ultrasonic cutter that, American GFM guarantees, does not leave uncut threads. The ply- picking system features a six-axis robot that organizes plies into kits in an indexing drawer system. The entire system is adaptable to a variety of ply lengths; simi- larly, each of the three zones can be adjusted in length depending on throughput and ply size requirements. In addition, smaller systems can combine the marking and cutting function. • DUNA-USA (Baytown, TX, US) featured the latest itera- tion of its Black Corintho tooling board, and had in its booth an epoxy-sealed tool made from the material. The tool was used to mold an autoclave-cured part made using Airtech International's (Huntington Beach CA, US) Beta Prepreg benzoxazine prepreg (see photo, p. 24). • Start-up MITO Materials Solutions (Stillwater, OK, US) introduced at SAMPE its MITO T-Series, a non-nanotube nanoadditive for use with epoxies, vinyl esters and polyesters to provide a 100% increase in toughness and an 80% reduction in mechanical failure risk. The mate- rial, which is loaded into resin at 0.1-0.2 wt%, also offers a thermal resistivity increase of 12-14°C. MITO T-Series is being targeted first toward recreational vehicle sidewalls, which have a poor history of stress cracking, which leads to substantial costs in warranty repairs. Another targeted application is in marine base resins to resist temperature increase caused by gel coat magnification.
