Technical Datasheet Panex® 30 Fabric (PW03, PW06, SW08) Graphitized Spun Yarn Carbon Fabric Description Panex® 30 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. Panex® 30 materials undergo a vacuum graphitizing process and long temperature soak, resulting in a very thermally stable and chemically pure fabric with low oxidation rate. Material Overview Plain Weave (PW03) SI US Plain Weave (PW03) Applications Applications of composites fabricated with Panex® 30 Woven Fabrics include low cost carbon-carbon materials and other processes where chemical vapor infiltration or prepregging is required.
