Panex 35 is the low-cost commercial carbon fiber that has revolutionized the carbon fiber industry. It is made from our abundant textile-based precursor and manufactured in a proprietary high-throughput process that allows it to be the lowest cost commercial carbon fiber on the market. Panex 35 is the dominant carbon fiber in the wind turbine industry and is on the forefront of many other applications including infrastructure, automotive, pressure vessels, offshore drilling, and other industrial applications.
Spool-to-Spool Consistency – By controlling the process from precursor manufacturing to carbonization and maintaining ISO 9001:2008 and AS9100 certifications, Panex 35 continues to exhibit superior levels of consistency from spool to spool for critical properties and characteristics.
Panex 35 Continuous Tow (50K) is the premier commercial carbon fiber on the market. Is is a 50K filament fiber manufactured from polyacrylonitrile (PAN) precursor, and is available with a range of sizings for optimal processing and compatibility with a variety of resin systems. Zoltek’s quality system focuses on spool-to-spool consistency yielding low coefficients of variation. More on Continuous Tow.
Panex 35 Chopped Carbon Fibers are commonly compounded with general engineering thermoplastics (eg: PC, Nylon, etc.) and high-temperature thermoplastic resins (eg: PEEK, PEI, etc.). The resulting composite offers high strength-to-weight and stiffness-to-weight ratios. Our chopped fibers have a high bulk density value, which allows for cleaner and more consistent flow rates. The also distribute easily during compounding, thereby improving process and product performance. Our chopped fibers are available in a pellet, flake, or stick form. More on Chopped Fiber.

Panex 35 Milled Fibers are specially processed PAN (polyacrylonitrile) based fibers for high-volume applications that require strength and/or electrostatic dissipation. Zoltek’s in-house milling system ensures product quality and traceability from raw material through finished product. More on Milled Fiber.
Panex 35 Stitch-Bonded Uni-directional Carbon Fabrics are produced from our Panex 35 50K Continuous Tow. Unique fiber spreading techniques enable a wide range of fabric weights and constructions for composite part applications. Our fabrics have been specially constructed for enhanced infusibility, and allow for a rapid build-up of part thickness. More on Uni-directional Fabrics.
Panex 35 Tow Weave Carbon Fabrics are produced from our Panex 35 50K Continuous Tow. Quick composite part build-up is cost effectively achieved with our cosmetically attractive carbon fiber fabrics. Applications include large composite tooling parts and aesthetically appealing finished composite components. More on Woven Fabrics.
Zoltek’s uni-directional prepreg tapes are made with Panex 35 carbon fiber, and available in areal weights from 150 gsm to over 900 gsm. Our prepreg is ideal for rapidly building part thickness with excellent composite properties, and allows for higher manufacturing throughput at a lower cost. A wide selection of epoxy resin formulations meets a variety of processing and composite property requirements for tack, toughness, flow in cure, surface finish, cure time, cure temperature, and delivered composite strength and modulus. Custom formulations are also available. More on Prepreg Tapes.
Zoltek’s needlepunched felts are produced from Pyron oxidized PAN fibers and later carbonized to 95% carbon content in our vacuum furnaces. Current applications include insulation in high-temperature furnaces, filtration media in high-temperature and/or corrosive environments, and energy storage. The unique properties of Panex 35 carbon felts are optimal for complex thermal, corrosive or conductive applications. More on Felts.
