Saertex® 440 GSM Stitched Triax

High-Strength Lighter Weight

Saertex® 440 GSM Stitched Triax Overview

This Saertex® 440 g/m² (13 oz/yd²) 12" wide, stitched triaxial cloth is designed to add high strength in all directions for finished composite parts. High-strength polyester is used to stitch bundles of fiberglass at +/- 45 degrees, with larger bundles at zero degrees.

Fibers are not crimped and fabric lays smooth, promoting maximum strength properties.

This fabric is ideal for wet lay-up and infusion, and can be used with epoxy, polyester, and vinyl ester resin systems. It is thicker, however, and not suitable for small details.

The Saertex brand ensures top quality in this category. In addition, the Fibre Glast First Quality commitment means you can expect the same finish, sizing, and handling characteristics every time you order

Why Choose Stitched Triaxial Over Biaxial?

While biaxial fabrics provide strength in two directions (+/- 45 degrees), the triaxial construction adds larger bundles at zero degrees, providing strength in all three directions within a single layer. This eliminates the need to stack separate plies at different orientations to achieve multi-directional strength.

Stitched fiberglass fabrics are bundled and stitched together, rather than woven, so there is no crimp in the yarn. As a result, these reinforcements offer optimized directional strength for finished composite parts. For this reason, stitched fiberglass fabrics are popular in the wind energy industry.

The 12" width of the #2907 makes it well suited for targeted reinforcement applications where the full 50" width of the larger stitched fabrics would be excessive. This narrow format is ideal for reinforcing specific structural areas or adding strength along defined load paths.

How Should Saertex 440 GSM Stitched Triax Be Used for Best Results?

The vacuum infusion process offers a better fiber-to-resin ratio than hand lay-up or vacuum bagging, and stitched fabrics are specifically designed for fast wet-out in infusion applications.

Available as cut-to-length yardage (#2907, min 10 yd), 1-yard roll (#2907-A), 3-yard roll (#2907-B), and 5-yard roll (#2907-C).

Rolled fabrics ship in a long (45", 53", or 62") box. Click below on the "What to expect when you order Fabric" video to see how rolled fabrics are cut and shipped each time you order.

This fabric is sold by the linear yard, either as a prepackaged quantity or by continuous yardage. Prepacks This fabric is available in pre-cut lengths that measure one yard (#2907-A, roll), three yards (#2907-B, roll), and five yards (#2907-C roll). Each is packaged and sold separately. For your convenience, these "prepacks" can be purchased in any combination. However, if the length for any one fabric totals 10 yards or more, we suggest you purchase it in continuous, "cut to length" yardage. Continuous, "Cut to Length" Yardage If you know in advance that you intend to purchase 10 yards or more of any one fabric, it should be ordered in continuous, "cut to length" yardage. In this case, fabric will be cut once according to the total yardage ordered, and customers receive a price-per-yard discount as compared to prepacks. Quantity discounts continue to deepen as the yardage increases for any one cut of one fabric.
