Panex® 35 Continuous Tow (50K) Datasheet Germanischer Lloyd Approved, Approval No. WP 1030012 HH Commercial Carbon Fiber for Industrial Applications PANEX® 35 continuous carbon fiber is manufactured from polyacrylonitrile (PAN) precursor. The consistency in yield and mechanical properties that are provided by large filament count strands gives the user the ability to design and manufacture composite materials with greater confidence and allows for efficient and fast buildup of carbon fiber reinforced composite structures. PANEX® 35 50K fibers are available with a variety of sizing formats for different composite processing methods and for compatibility with a wide range of standard resin systems. Zoltek quality focuses on spool to spool consistency yielding low coefficients of variation. 1,500 meter spool Panex® 35 Typical Properties * English Units SI Units Tensile Strength 600 Ksi 4137 Mpa Tensile Modulus 35 Msi 242 GPa 0.00061 ohm-in 0.00155 ohm-cm Density 0.065 lb/in3 1.81 g/cc Fiber Diameter 0.283 mils 7.2 microns Carbon Content 95% 95% 400 ft/lb 270 m/kg Spool Weight 12 lb 5.5 kg Spool Length 1640 yd, 3280 yd 1500 m, 3000m Electrical Resistivity Yield * fiber properties generated using ASTM standard methods Zoltek Corporation | 3101 McKelvey Rd. | St. Louis, MO 63044 P: 314-291-5110 | F: 314-291-8536 | E: [email protected] | W: www.zoltek.com
