ZOLTEK’s™ Pultruded Profiles are pre-cured, thick-ply carbon fiber laminates for ideal structural reinforcement applications. Available in a variety of thicknesses and complex shapes, our pultrusion products deliver optimized properties with high fiber volumes, nearly zero void content, and locked-in filament alignment.

ZOLTEK PX35 carbon fiber tows are fed into our proprietary impregnation and curing process which creates smooth carbon fiber laminates resulting in efficient laydown when building thickness. The specific fiber alignment achieved with pultrusion delivers consistently better overall properties in laminates than any other composite manufacturing process. Depending on the end application, these pultruded profiles are typically produced with a thermoset epoxy or vinyl ester resin in a proprietary low-cost, high-throughput process.

Pultruded profiles are production-ready carbon composites for infrastructure applications, deep sea exploration, wind energy, and other applications benefiting from the unique properties of pultruded carbon fiber parts.

ZOLTEK, together with Toray, has developed a new innovative technology and input material for Sheet Molding Compound (SMC) for compression molding. SMC is a material consisting of resin and chopped carbon fiber which is placed into matched metal tooling to mold a finished part.

The new carbon fiber tow product still consists of a large tow (50K), but it is now split into 3K sub tows, so that when chopped it breaks apart into a homogeneous isotropic bed of small tow carbon fiber which is easily wet out in the SMC process. The resulting molding compound produces a revolutionary strong and stiff composite part suitable for automotive and other applications.

Final parts molded from SMC benefit from a high throughput compounding process coupled with low cost inputs (resin and fiber). Further, the molding process is highly efficient with very low waste. More than 97% of the compound is used in the final molded part with very little edge trim or other scrap.

ZOLTEK has specifically designed continuous tow, chopped fibers, and milled fibers for both general and high-temperature engineering thermoplastics. To further optimize the solutions provided, ZOLTEK has also developed specific sizing technology for all major thermoplastic materials. The end result is a revolutionized approach to thermoplastics in which compounders can achieve physical property improvements that will move thermoplastic into new application areas. With this technology, nylon compounds can replace traditional cast aluminum and Mg applications. PP compounds can compete with higher density filled materials or vertical panel applications. Higher heat materials have already been compounded for use in 3D printed tooling.

Our portfolio of sizings are compatible with Nylons, Polycarbonates, and several high-temperature thermoplastics (PEI, PEEK, PPS, etc.).

Each ZOLTEK PX35 thermoplastic-optimized fiber has its benefits. High bulk density values allow for cleaner, more consistent flow rates. Chopped fiber is available in various lengths for thermoplastic compounding. Milled fiber is available in pellet form of as a dry powder. The compact pellet form maintains its integrity from the package through the hopper and distributes easily during compounding, improving process and product performance
