Carbon Fiber Fabric Biaxial +/-45 Degree 50k 50in/127cm 4.42oz/150gsm Zoltek PX35 Fiber
Description
Carbon Fiber Fabric – Biaxial ±45° (50k) · 50in/127cm · 4.42oz/150gsm · Zoltek PX35
This professional-grade carbon fabric is built from Zoltek PX35 50k tow and stitched into a non-crimp biaxial layup with fibers oriented at ±45°. The NCF construction keeps the tows straight for efficient load transfer while the light binder stitching stabilizes the cloth for handling. It is an excellent choice for adding shear/torsional strength and building laminate thickness quickly.
Why choose this fabric
- Balanced ±45° architecture – ideal for shear, torsion and off-axis loading.
- Non-crimp (NCF) – minimal tow waviness for improved mechanical properties vs. woven fabrics.
- Lightweight 150 gsm (4.42 oz) – adds bulk with minimal weight gain.
- 50in (127 cm) width – efficient coverage for mid- to large-size laminates.
- Zoltek PX35 50k carbon – proven, high-value PAN-based fiber for structural parts.
Recommended uses
Structural plies in composite panels, tubes and beams, torsion boxes, marine and automotive skins, UAV/robotics parts, and as a fast build-up layer beneath a cosmetic outer fabric. (Not recommended as the visible cosmetic layer due to stabilizing stitch lines.)
Processing
- Compatible with epoxy, vinyl ester, and polyester resins.
- Suitable for wet layup, vacuum bagging, and resin infusion.
- To harden the raw fabric into a usable laminate you will need the appropriate resin or epoxy for your project.

Sold by the linear yard (36" length x 50" width) Multiple yards are rolled on one continuous roll when possible.
How We Sell
We sell this fabric by the linear yard. You will receive a continuous piece of fabric at the width listed.
For example, if the fabric is 50" wide, a quantity of 1 (linear yard) equals a continuous piece measuring 50" wide × 36" long. A quantity of 5 (linear yards) equals a continuous piece measuring 50" wide × 180" long.
