Carbon Fiber 3K Tow Overview

3K carbon fiber tow (3,000 monofilaments per tow) is the most popular and versatile grade in our carbon fiber portfolio. It offers an excellent balance of tensile strength, modulus, and weaving processability — making it the default choice for automotive, sporting goods, marine, drone, and general industrial composite parts.

GX400-3K Carbon Fiber Tow — Wet-Spun | JiLin Tangu

GX400-3K wet-spun PAN-based carbon fiber tow — general-purpose wet-spun grade

Tensile strength 4,200–4,500 MPa · Modulus ≥235 GPa

Low density 1.77±0.03 g/cm³ · soft handle & excellent resin wettability

For prepreg, vacuum infusion (VARTM), and composite reinforcement

Carbon fiber is a continuous filament with excellent mechanical properties, low density, heat and corrosion resistance, fatigue resistance, a small thermal expansion coefficient, and good electrical and thermal conductivity — properties that translate directly into lighter, stronger, and more durable composite parts.
