13 Oz Fiberglass Unidirectional 50"
Engineered for high-performance composite laminates, our 50" 13 oz Unidirectional Fiberglass Fabric delivers unmatched directional reinforcement. Built with continuous, non-crimp parallel E-glass fibers held together by fine cross-stitching, this fabric allows you to align maximum tensile and flexural strength directly along your primary load paths—without adding unnecessary weight or thickness in secondary directions.
Whether you're reinforcing boat hulls, building custom automotive panels, or executing structural composite repairs, this 50-inch wide roll provides broad, seamless coverage for fast and efficient layups.
Key Benefits & Features
-
Directional Reinforcement: Unidirectional orientation maximizes stiffness and tensile strength along the 0° axis.
-
Optimal Resin Wet-Out: Non-crimp parallel strands absorb resin quickly and thoroughly, ensuring lightweight, high-density laminates.
-
Clean Handling & Fraying Resistance: Fine perpendicular stitching holds individual fibers straight during cutting, placing, and wetting out.
Our fabrics are sold by the linear yard. The unit price displayed is for 1 linear yard; all volume discounts will be automatically applied when selecting larger quantities of fabric when added to your shopping cart, as indicated in the table above with quantity discount ranges for units purchased. Please purchase the number of linear yards that you require. When purchasing multiple yards of the same fabric, you will receive one continuous length of that material. We carefully take that material and roll it onto a cardboard core and wrap clear plastic
*Our shipping calculator recognizes fiberglass, vacuum bagging materials and any other item that is shipped on a roll as an individual parcel and charges for each item. If you are ordering more than one part number shipped on a roll or additional small items in most cases we can combine these into one parcel and charge a lower shipping rate. Please call us if your checkout shipping seems unusually high. We charge an additional $10.00 packaging fee for fabrics and vacuum bagging supplies.
