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.
