Fabrics • Unidirectional • Biaxial • Multiaxial • Custom
![Page 10: Engineered Braided Fabrics Enable Significant Cost Savings](https://reader030.vdocuments.mx/reader030/viewer/2022040714/624ce99b7b658f04f21518cf/html5/thumbnails/10.jpg)
No Crimp Unidirectional Fabrics – Highly Efficient and Very Affordable
Only small percentage of binder (less than 3%) on one side – no crimp offers direct translation of properties
Offered in 4 oz., 9 oz., and 22 oz. fabric weights in standard and intermediate Modulus.
Unidirectional
![Page 11: Engineered Braided Fabrics Enable Significant Cost Savings](https://reader030.vdocuments.mx/reader030/viewer/2022040714/624ce99b7b658f04f21518cf/html5/thumbnails/11.jpg)
+/-45° fabric without cutting, stitching or manipulation
Highly drapable and conformable
Off the roll +/-45° reduces manufacture time and results in less waste
Widths from 20” – 52” and fabric weights from 5.8 oz/yd² to 21 oz/yd²
Biaxial
![Page 12: Engineered Braided Fabrics Enable Significant Cost Savings](https://reader030.vdocuments.mx/reader030/viewer/2022040714/624ce99b7b658f04f21518cf/html5/thumbnails/12.jpg)
• Braided, triaxial fabric reinforcement
• Each ply is balanced and symmetric; inherently Quasi-ISOtropic
![Page 13: Engineered Braided Fabrics Enable Significant Cost Savings](https://reader030.vdocuments.mx/reader030/viewer/2022040714/624ce99b7b658f04f21518cf/html5/thumbnails/13.jpg)
Why?
• Superior performance
• Simple and efficient processing • Reduction in scrap waste
Better. Faster. Cheaper.
