Build Bulk, Strength and Stability for Molds

When you're looking to build thickness into a mold with limited time, this #254 tooling fabric is the right choice. It is typically placed at the heart of a mold to build bulk, strength, and dimensional stability. 

This fabric offers very high strength characteristics as well as rapid build-up. Apply to molds as a back-up shell once the finer surfacing layers are in place.   


  • Very high strength characteristics as well as rapid build-up.
  • Ideal for building high-strength tooling.
  • If requested, this fabric can be certified to meet the requirements of: AMS-3824 Style 7587 and ASTM D 4029-09 Style 7587. 


  • Fabrics need to be oriented so the fiber yarns run parallel to the expected loads. 
  • Lighter fabrics are generally added as a surface layer to prevent show-through of its more textured weave.
  • Use with epoxy resin, polyester resin, or vinyl ester resin to produce composite parts of excellent strength, low weight, and great cosmetics.
  • To create the highest quality molds, use with our #1110 Vinyl Ester Resin, or the System #2000 Epoxy.

Folded prepacks are typically shipped in a small box, or packaged in a box with other items on your 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.


20 oz Tooling Fabric 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 (#254-F, folded package), three yards (#254-A, folded package), and five yards (#254-B folded package). 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.
