Tenax® filament yarn is a high-tech carbon fiber product, which significantly enhances properties in thermoset and thermoplastic composites, including aerospace, automotive and general industrial applications.

Tenax® filament yarn features a high tensile strength as well as a high tensile modulus. It is available in qualities ranging from 67 to 3200 tex or 1,000 to 48,000 filaments.

Ideally suited for all common processes (e.g. for prepregging, filament winding, pultrusion and weaving, braiding), Tenax® filament yarn is surface treated to improve fiber-to-resin interfacial bond strength. In addition, fiber sizing is applied to protect the fiber and to improve handling and wet-out. A wide variety of available sizings make it fully compatible with thermoset matrix systems (epoxy, polyurethane and vinylester). Our tailored thermoplastic sizing is compatible with several thermoplastic matrix systems (e.g. PEEK, PEI, PA).
