Why Triaxial Spread Tow Outperforms
Conventional Woven Carbon Fabric
Yarns cross over and under each other thousands of times per square meter, and every crossing crimps the fiber. Crimped fiber cannot carry load the way a straight fiber does - so part of the fabric's theoretical strength is lost before the part is even laminated, and the weave also resists draping over tight radii.
| ✕ Fiber crimp at every crossing |
| ✕ Theoretical strength partly lost |
| ✕ Resists draping over tight radii |
Triaxial Spread Tow Carbon Fabric
Removes that compromise: spread tows laid in 0° and ±45° directions keep the fibers flat, so reinforcement performance is preserved and the fabric conforms to curved moulds with far less effort.
| ✓ Fibers stay flat - no crimp |
| ✓ Full reinforcement performance preserved |
| ✓ Conforms to curved moulds with less effort |
Technology
Three Mechanisms Behind the Performance
Spread Tow Construction
Each carbon tow is widened into a flat tape, reducing crimp and improving surface uniformity - which also reduces resin-rich pockets and improves fiber volume fraction.
Triaxial Architecture
Fibers running in three directions (0°/±45° in the standard configuration) give the laminate a quasi-isotropic response, distributing load in multiple directions instead of only along the warp and weft.
Structural Stabilization
The layers are held in place - by stitching or a thermoplastic binder - so the architecture survives handling, cutting and layup without shifting. Areal weight, width and fiber specification are produced to customer requirements.
Why spread tow instead of standard carbon fabric? - Lower Crimp, Higher Mechanical Performance
Spread tow fabric keeps the carbon fibers straight, while standard woven fabric forces them to crimp at every crossing. Straight fibers carry load more efficiently, so spread tow construction preserves more of the fiber's inherent tensile and flexural performance, produces a flatter surface with more uniform resin distribution, and reduces the resin-rich pockets that weaken a laminate.
Which fiber orientations does it use? - Triaxial 0° / ±45°, Quasi-Isotropic
he standard triaxial configuration is 0° / +45° / −45°, which delivers a quasi-isotropic response - load is carried in multiple directions rather than only along warp and weft.
How easy is it to drape over complex shapes? - Superior Conformability
Because the tows are spread flat rather than crimped over each other, the fabric drapes and conforms to curved moulds, tight radii and complex geometries with less wrinkling and less manual working. That means faster layup, less operator skill dependency, and fewer void defects in the finished part.
What areal weights and widths can I order? - Built to Your Specification
Areal weight (gsm), roll width and fiber specification are produced to the customer's requirement rather than fixed at catalogue values, so one supplier covers lightweight surface layers and heavier structural plies.
How is the fabric stabilized? - Stitching or Binder Options
The three fiber directions must be held in position, and that is done either by stitching or by a thermoplastic binder, depending on the application and the resin system. Stitching gives mechanical integrity for handling; a binder keeps the fabric clean and compatible with specific resin processes.
Who manufactures it, and can it be customized? - Haining Yixin, Multi-Axial Loom Producer
The fabric is produced by Haining Yixin New Material Co., Ltd., established in 2013, specializing in high-performance fiber fabrics since then. Production runs on Dornier air-jet looms and multi-axial looms - the equipment class required for multi-directional reinforcement fabrics - and the company holds multiple patents, several of which filled gaps in the industry. Customized fiber specification, areal weight and width are supported, with free samples available.
How It Works
1. Carbon tows are spread - widened into flat tapes - so the filaments sit side by side instead of bundled in a round cross-section.
2. The spread tows are laid in three fiber directions (0° and ±45° in the standard configuration) rather than interlaced over and under each other.
3. Because the fibers are not crimped, load travels along straight filaments when the laminate is stressed.
4. The three directions distribute load across the laminate, producing a quasi-isotropic response instead of a warp/weft-only response.
5. The layers are stabilized by stitching or a thermoplastic binder so the architecture survives cutting, handling and layup.
In short: spread tows → straight fibers → low crimp → multi-directional load path → stable, drapable reinforcement.
Why Choose Haining Yixin
The equipment class that multi-axial fabric requires. Production runs on Dornier air-jet looms and multi-axial looms - the machines needed to place fibers in multiple directions with stable, repeatable tension. That is what makes consistent triaxial quality possible batch after batch.
Specialist since 2013. Haining Yixin New Material Co., Ltd. has focused on high-performance fiber fabrics for over a decade: carbon fiber fabrics, aramid fiber fabrics, and anti-cut / stab-resistant / anti-bite fabrics, with business relationships across many countries and regions.
Innovation on record. The company holds multiple patents, several of which filled gaps in the industry - innovation-driven development is the stated enterprise strategy.
Customer-demand centred. Areal weight, width and fiber specification are produced to your requirement; "make customer demand our centre" is company policy, not a slogan.
Low-risk evaluation. Free samples and customized orders, so you can validate the fabric in your own layup and test programme first.
Buyer Questions
Q1: What is triaxial spread tow carbon fiber fabric?
A: It is a composite reinforcement fabric made from spread carbon tows laid in three fiber directions - typically 0° and ±45°. Spreading widens each tow into a flat tape, which reduces crimp and preserves mechanical performance while giving the fabric a quasi-isotropic response.
Q2: What is the difference between spread tow and standard woven carbon fabric?
A: In standard woven fabric, yarns cross over and under each other, crimping the fibers and reducing their load-carrying efficiency. Spread tow fabric keeps fibers flat and straight, which lowers crimp, improves surface uniformity and reduces resin-rich pockets.
Q3: Which fiber orientations are available?
A: The standard triaxial configuration is 0° / +45° / −45°. Other multi-axial configurations can be discussed for specific laminate designs - share your ply schedule and we will confirm feasibility.
Q4: How is the fabric stabilized, and does that affect my resin process?
A: The fiber layers are held in place either by stitching or by a thermoplastic binder. Tell us your resin system and process (hand layup, infusion, prepreg), and we will recommend the appropriate stabilization method.
Q5: Can you produce custom areal weight, width and fiber specification?
A: Yes. Areal weight, roll width and fiber specification are produced to customer requirements, and customized orders are welcome. Send your target specification and we will confirm the matching construction.
Q6: Can I get a free sample for layup and mechanical testing?
A: Yes. Free samples are available from our factory so you can run your own layup trials and mechanical tests before committing to volume production.
