In the world of materials, carbon fiber has emerged as the ultimate team player, one that works miracles in reinforcing other materials and lifting them to new levels of performance.

At Zoltek, we view our role in a similar light. Our objective as a company is to lead the commercialization of carbon fiber as a primary composite building material. It is our goal to help others achieve new levels of performance across a range of products. Carbon fiber reinforced composites are remarkable in their performance characteristics and properties that include high strength, low weight, high stiffness, corrosion resistance, heat resistance, and electrical conductivity.

Another important characteristic of carbon fiber is its versatility. Carbon fiber has the ability to work with an assortment of different materials, including other fibers, plastics, metals, wood, and concrete. As a result of this versatility, it is impossible to postulate all of the potential uses of carbon fiber in maximizing performance and lowering life-cycle costs across a range of consumer and industrial products, and across all types of construction.

Zoltek has become the worldwide leader in rated capacity for producing carbon fiber by making low-cost, high performance carbon fiber through a proprietary continuous carbonization process. Using this knowledge, it is well within our power to truly open the floodgates of demand across a variety of industries.

Our portfolio includes grades sized to be compatible with polypropylene, nylon, polycarbonate, and multiple high-temperature thermoplastics.
ZOLTEK fibers offers improvesd dimensional stability and mechanical properties, increased conductivity and static dissipation, high strength-to-weight and stiffness-to-weight ratios, greater thermal stability and ease of feeding and processing.

ZOLTEK

ZOLTEK produces uni-directional (UD) prepreg tapes based on ZOLTEK carbon fiber. ZOLTEK prepreg is ideal for large-volume composite applications where high production throughput, excellent composite properties, and low material cost are important. A wide selection of epoxy resin formulations meet most processing and composite property requirements for tack, toughness, surface finish, cure time, cure temperature, and delivered composite strength and modulus. Custom formulations are also available. ZOLTEK prepreg properties, such as fiber areal weight (FAW), resin content, and width, are readily adjusted to exactly meet customer requirements. Packaging options include core size, customer specified knitting requirements, and custom labeling. ZOLTEK prepreg production is geared to large volumes and low cost. Special projects are welcomed.

ZOLTEK™ PX35 PREPREG TAPES

ZOLTEK PX30 Woven Carbon Fabrics tailorability results from controlling the yield on rovings and yarns, and allows for a variety of finished composite thicknesses. The spun yarns have many surface fibrils that protrude in various directions at various lengths from the surface. This fiber loft contributes to high cross-ply tensile and interlaminar shear strengths for 2-D composite materials. Contour conformation without wrinkling is another advantage of spun yarn fabrics. ZOLTEK PX30 materials undergo high temperature carbonization process, involving a long temperature soak time, resulting in a very thermally stable and chemically pure fabric with low oxidation rate.

ZOLTEK™ PX30 FABRIC SW08

Zoltek has developed a new product and sizing chemistry for use in vinyl ester resin systems. Introducing Zoltek’s PX35 Vinyl Ester Compatible Tow product. This new product, based on our proprietary sizing chemistry, exhibits excellent adhesion to and compatibility with vinyl ester resin systems. Most carbon fiber products are used to reinforce epoxy resin systems. Recently, the demand has grown for a product and sizing chemistry that can be used in vinyl ester resins whether cured thermally or via room temperature infusion. When compared to Zoltek’s standard carbon fiber product, PX35 Epoxy Compatible Tow, the new vinyl ester compatible product has significantly higher interlaminar shear strength (ILSS) and transverse flexural strength TFS, which both measure and indicate fiber to resin matrix compatibility and adhesion, as well as, composite performance. Zoltek’s PX35 Vinyl Ester Compatible Continuous Carbon Fiber is manufactured from a polyacrylonitrile (PAN) precursor fiber. The consistency in yield and mechanical properties that are provided by large filament count strands gives the user flexibility to design and manufacture composite materials.

ZOLTEK™ PX35 VINYL ESTER COMPATIBLE TOW

ZOLTEK PX35 Stitch-Bonded Uni-Directional Carbon Fabrics are produced from our ZOLTEK PX35 50K Continuous Tow Carbon Fiber. Unique fiber spreading techniques are utilized to obtain a wide range of UD fabric weights for a varied set of composite part applications. Quick composite part build-up is cost effectively achieved with our diverse weight range of low-cost carbon fabric products.

ZOLTEK™ PX35 UD200

ZOLTEK PX35 Tow Weave Carbon Fabrics are produced from our ZOLTEK PX35 50K Continuous Tow Carbon Fiber. Quick composite part build-up is cost effectively achieved with our cosmetically attractive carbon fiber fabrics. Applications include large composite tooling parts and esthetically appealing finished composite components.

ZOLTEK™ PX35 P/TW28-50

ZOLTEK’s PX35 Milled Fibers are specifically processed PAN (polyacrylonitrile) based fibers for lower cost applications. ZOLTEK PX30 High Purity Milled Fibers are 99+% pure carbon fibers derived from ZOLTEK’s high temperature batch graphitization process. All ZOLTEK milled products are free of any sizings. ZOLTEK’s in-house milling system ensures product quality and traceability from raw material through finished product.

ZOLTEK™ PX35 UD600

ZOLTEK’s PX35 Flake Type chopped fibers provide ready impregnation of thermoset resins, with the capability to mold complex shapes. The resultant carbon fiber/ resin matrix composites offer high strength-to-weight and stiffness-to-weight ratios. Zoltek PX35 Flake Type chopped fibers may also be used as a low-cost alternative in thermoplastic applications, whereby a small portion of the matrix-specific product can be replaced with chopped flake carbon fibers with negligible impact to composite properties.

ZOLTEK™ PX35 CHOPPED FIBER (TYPE-13)

ZOLTEK PXFT carbonized felts are produced from 100% ZOLTEK OX felts, being continuously carbonized and supplied in roll form. ZOLTEK PXFT carbonized felts can be used in many applications, including: stationary energy storage batteries, fire protective insulation, high temperature furnace linings, acid gas mist eliminators and in carbon composite materials. Customers can apply their own post treatments and the carbonized felt is easy to cut and process for specific enduse applications.
