Material Notes:
HexTow™ AS4 carbon fiber is a continuous, high strength, high strain, PAN based fiber available in 3,000 (3K), 6,000 (6K), and 12,000 (12K) filament count tows. The fiber has been surface treated and can be sized to improve its interlaminar shear properties, handling characteristics, and structural properties, and is suggested for use in weaving, prepregging, filament winding, pultrusion, and molding compounds. Sizing compatible with various resin systems are available to improve handling characteristics and structural properties.Information provided by Hexcel
