Style 6781 S2-Glass

Superior Strength among Fiberglass Fabrics

This 9-ounce fabric selection is much like our #543 9-ounce E-Glass, except that it is woven from S2 fibers. As a result, this S2-Glass features extraordinary strength with a superior look and finish. Style 6781 is one of the most popular fabric for modern aerospace applications.

In the #1543, glass fibers are bundled and woven repeatedly to float over seven bundles, then under one. As a result, the fabric is flatter and more easily draped over the most complex shapes, especially when compared to plain weaves.

Features

• Satin weaves are flatter than other weaves and conform to shapes easily.
• S2 Fibers in an 8H Satin Weave provides extraordinary strength with a superior look and finish.
• High heat and chemical resistance.
• Most popular aerospace fabric used today.
• If requested, this fabric can be certified to meet the requirements of: AMS-C-9084 Type VIII-B (Class 1 & 2), with exception for fiber type. SCG 75 replaces ECDE 75 fiber.

Tips

• Although they conform well to shapes, satin weaves can be more easily distorted than other weaves.
• Each side of this fabric is either largely fill or warp fibers, so opposite sides will look much different. To produce a symmetrical laminate, invert half the plies.
• Use with epoxy resin, polyester resin, or vinyl ester resin to produce composite parts of excellent strength, low weight, and great cosmetics.
• To maximize strength in parts, use with an epoxy, like our System #2000.

Why Choose S2-Glass Over E-Glass?

Both the #1543 S2-Glass and the #543 E-Glass share the same 8H satin weave construction and similar weight range, but the S2 fiber delivers significantly higher strength values. The #1543 achieves warp strength exceeding 250 lbs/inch and fill strength exceeding 200 lbs/inch, compared to the #543 E-Glass at >150 lbs/inch warp and >130 lbs/inch fill. This strength advantage comes from the S2 fiber itself, which offers superior heat and chemical resistance compared to standard E-Glass.

The aerospace satin weaves should be used wherever the highest physical properties are needed. In a satin weave, one filling yarn floats over several other warp threads before being stitched under another warp fiber. Threads run straighter for much longer in this loosely woven type, maintaining the theoretical strengths of the fiber.

What Are the Best Applications for S2-Glass?

Aviation relies heavily on lightweight, high-strength materials to improve fuel efficiency, performance, and structural integrity. The extraordinary strength with a superior look and finish makes it ideal for aerospace parts where standard E-Glass does not meet performance requirements. The S2-Glass is also suitable for high-performance marine and sporting goods applications where the higher strength of S2 fiber justifies the cost premium over E-Glass.

How Should S2-Glass Be Used for Best Results?

Once cut, satin weaves can unravel more easily because each thread is not held as tightly as in a plain weave.

To maximize strength properties of fiberglass, it should be used with an epoxy resin, and can be cured using standard lamination techniques with no special tools or methods required.

Available as cut-to-length yardage (#1543, min 10 yd), 1-yard roll (#1543-A), 3-yard roll (#1543-B), and 5-yard roll (#1543-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.

Style 6781 S2-Glass 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 (#1543-A, roll), three yards (#1543-B, roll), and five yards (#1543-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.
