PX30 Header ZOLTEK™ PX30

ZOLTEK™ PX30 products are PAN based materials that are >99% carbonized. These high-purity products are derived from ZOLTEK’S™ high temperature batch carbonization process. They are most often used in extreme applications that demand resistance to harsh temperature and chemical environments. All ZOLTEK™ PX30  materials are thermally stable and chemically pure.

The following is a list of product forms and typical applications and uses:

  • Woven Fabrics: aircraft & automotive brakes, clutch plates, gas diffusion layer for fuel cells, etc.
  • Scrim Fabrics: designed with an open weave ideal for lightweight secondary reinforcement
  • Rovings and Spun Yarns: used for carbon/carbon preforms, or braided compression packings & seals
  • Felts: widely used for energy storage and filtration media in corrosive environments

Product Forms

ZOLTEK™ PX30 woven carbon fiber fabrics made from spun yarn that is tailored for a variety of finished composite thicknesses. These fabrics have high cross-ply tensile and interlaminar shear strengths in composite materials. Another advantage of these fabrics is their contour conformation without wrinkling. ZOLTEK™ PX30 fabrics are thermally stable and chemically pure with low oxidation rates. More on ZOLTEK™ PX30 Fabrics.

Applications of ZOLTEK™ PX30 woven fabrics include carbon-carbon composites and other processes where chemical vapor infiltration or prepregging is required.

Applications: Energy Storage | Friction Resistance | Aircraft & Automotive Brakes | Clutch Plates |Gas Diffusion Layer for Fuel CellsMore



ZOLTEK™ PX30 carbon fiber yarns are >99% carbonized and have a density of 1.75 g/cc. These yarns are characterized by their many surface fibrils protruding in various directions, making them ideally suited for high performance applications including carbon/carbon and other refractory composites. More on ZOLTEK™ PX30 Yarns.

Applications: Energy Storage | Friction Resistance | Carbon/Carbon Preforms | Braided Compression Packing & Seals



ZOLTEK™ PX30 Roving is manufactured with high twist to improve its handling characteristics. The roving is widely used as a baseline material for the manufacture of friction clutches and brakes. Thick fabrics woven of ZOLTEK™ PX30  HIGH TWIST ROVING allow for efficient buildup during fabrication of composite substructures. More on ZOLTEK™ PX30 Roving.

Applications: Energy Storage | Friction Resistance | Filtration Media in Corrosive Environments



ZOLTEK™ PX30 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.
