Entec Composite Machines (Salt Lake City, UT, US) demonstrated its new FW750 filament winder and high-speed ST1 servo tensioner during CAMX 2014. The FW750 filament winder and high-speed servo tensioner are designed to manufacture pressure vessels for compressed natural gas (CNG) storage. It offers winding speeds of more than 3,430 mm/sec and a reported performance accuracy of ±0.09 kg. At the show, Entec wound CNG fuel tanks using Zoltek Corp.’s (St Louis, MO, US) Panex 35 TowPreg. The elimination of resin bath resulted in faster winding speeds, cleaner operations and an overall faster production throughput.
