Extremely thermally stable, ZOLTEK PX30 woven and knit fabrics are made from 100% ZOLTEK OX spun yarns designed to a specified thickness and areal weight. As a part of our commitment to innovation, ZOLTEK offers considerable versatility in our fabric forms including plain and satin weave constructions, and knit and scrim fabric types. Regardless of form, these fabrics provide superior tensile and interlaminar shear strength properties and easily drape, without wrinkling, particularly in composite materials. Due to the high carbon contents and low oxidation rates of ZOLTEK PX30 Fabrics, are particularly suited for carbon-carbon composites, fuel cell substrates, chemical vapor infiltration or prepreg processing and other thermally demanding applications.

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 carbon scrim is a plain leno weave fabric, produced from 100% ZOLTEK OX spun yarns, that undergo a proprietary high temperature, long carbonization soak process to obtain a high purity (>99% carbon) mesh material. The resultant chemically inert fabric exhibits superior thermal stability and a low oxidation rate, that overshadows any other option in the market. More specifically, ZOLTEK PX30 high-purity carbon scrim fabric is a specialized product. It is designed with an open weave construction ideal for applications requiring lightweight secondary reinforcement, such as that used in intumescent coating end uses. The scrim fabric is usually supplied with an FR coated finish for easy handling and installation. In addition, our ZOLTEK PX30 High-Purity Carbon Scrim Fabric is manufactured to the same high quality and high standards as all of the ZOLTEK PX30 woven products.
