Carbon Fiber Fabric Unidirectional 50k 5.9oz/200gsm Zoltek PX35 Fiber
Description
Description
Carbon Fiber Fabric — Unidirectional (UD) · Zoltek® PX35 · 50k · 5.9oz (≈200gsm)
This unidirectional (UD) carbon fiber fabric is produced with Zoltek® PX35 50k large-tow fibers. The reinforcement is concentrated in the 0° (warp) direction and held in place with a light cross-binder, giving you maximum axial stiffness and strength exactly where you need it. With an areal weight of 5.9 oz (≈200 gsm) and a full 50" width, this is a cost-effective workhorse for spar caps, stringers, panels and any laminate that benefits from directional reinforcement.
Key advantages
- True UD performance: Fibers aligned in the 0° direction for the highest possible axial properties.
- PX35 50k large-tow: Proven, reliable standard-modulus carbon fiber that balances performance and value.
- Easy handling: Light binder minimizes fray and keeps the tape stable during cutting and layup.
- Process-friendly: Compatible with epoxy (recommended), vinyl-ester and polyester; suitable for wet layup, vacuum bagging and infusion.
Typical uses
Spar caps and stringers, UAV/RC wings, marine foils and paddles, cycling and boardsport laminates, high-stiffness panels, tubes and beams. Pair with ±45° and 90° plies to tailor shear and transverse properties.
Technical details

Processing tips
- Orient the UD along your primary load path (0°). Add ±45° and/or 90° layers for balanced laminates.
- Consolidate under vacuum for the best fiber-volume fraction and surface quality.
- For cosmetic parts, seal and finish with a UV-stable clear coat or paint system.
