Prisma 24 oz Biaxial Cloth +-45 with T-mat Backing

Prisma Glass Biaxial cloth consists of 2 layers of parallel unidirectional fibers, each layer at a different orientation (+45°). Layers are held together by light stitching and backed with a polyester based T-mat (aka Trevira) backing that adheres tenaciously to bonding surface. 24 oz. per square yard material.

The same reinforcements that make Prisma preforms super tough are now available in this fabric form. Prisma Glass features exclusive T-Mat backing, where High Tenacity Thermoplastic fibers improve toughness and bonding. Perfect for boat repairs and new construction. The cloth and special backing work with Epoxy, Vinylester and Polyester resins. Build boats like the pros using the same Prisma materials the OEMs use.

Excellent strength characteristics for composite repairs to hull, transom, stringer, bulkhead and floor applications.

A great product.


I used it to reconstruct a curved teak box top. Teak deck strips were then glassed on top of the Biaxial w/T-mat backing cloth. This cloth is much easier to work with than equal weight woven roving or chopped strand in that it holds its shape well and strands don't shed out. It does require additional care to saturate and air bubbles needed more rolling to expel. I also used the cloth to do some deck repair and vacuum bagged it eliminating all bubbles and reduced the amount of epoxy needed to saturate it.
