Zoltek Corp. (St. Louis, MO, US) a manufacturer of industrial-grade carbon fiber, will highlight its PX35 product line, a low-cost industrial grade carbon fiber in various product forms, including tow, chopped, milled and pultruded plate. Zoltek says PX35 delivers strength-to-weight performance equal to or better than many aerospace carbon fiber grades. Based on a polyacrylonitrile (PAN) precursor, PX35 is manufactured with a proprietary high-throughput process that is said to produce an affordable fiber that doesn’t sacrifice strength or stiffness. Zoltek's fibers are targeted towards applications in the wind energy, automotive, structural reinforcements and marine markets.
