Entec Composite Machines (Salt Lake City) will perform live demonstrations of its new FW750 filament winder and high-speed ST1 servo tensioner during CAMX 2014. The company will also highlight its full range of filament winding machines and application solutions. The FW750 filament winder and high-speed servo tensioner are designed to provide accurate, high-speed and cost-effective filament winding for use in a range of applications, including pressure vessels for compressed natural gas (CNG) storage. It offers winding speeds in excess of 135 in/sec and a performance accuracy of ±0.2 lb. During the live demonstrations, Entec will wind CNG fuel tanks using Zoltek’s Panex 35 TowPreg, a pre-impregnated carbon fiber tow. When paired with Panex 35 TowPreg, the FW750 reportedly achieves greater fiber placement control due to the increased tack of material. This results in increased design freedom and more accurate burst pressure predictions when compared to traditional wet winding. The elimination of resin bath results in faster winding speeds, cleaner operations, and an overall faster production throughput.
