Saertex® 661 GSM UD

No-Crimp Fibers for Strength in One Direction

This Saertex® 661 g/m² (19.5 oz/yd²), 30" wide stitched unidirectional cloth is primarily designed to add strength in one direction for finished composite parts. Reinforced polyester threads are used to stitch large bundles of fiberglass at zero degrees, and small bundles at 90 degrees.

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

Unidirectional fabric is ideal for wet lay-up and infusion which require fast wet-out and strength control.

It can be used with epoxy, polyester, and vinyl ester resin systems.

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.

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 (#2910-A, roll), three yards (#2910-B, roll), and five yards (#2910-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.
