HexTow® AS7

Carbon Fiber (Industrial)
Product Data Sheet

HexTow® AS7 carbon fiber is a continuous, high strength, high strain, PAN based fiber available in 12,000
(12K) filament count tows. This 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, braiding, and pultrusion.
AS7-GS 12k (0.5%) carbon fiber has been qualified to NMS 818 Carbon Fiber Specification (NCAMP). This
allows customers to call out an industry standard, aerospace grade carbon fiber without the need to write and
maintain their own specification.
