Woven Rovings

Product Overview

Our Woven Rovings consist of continuous bundles of E‑CR glass filaments, interlaced in a balanced 0°/90° weave to provide high tensile and flexural strength in both longitudinal and transverse directions. Featuring 3B’s proprietary silane-based sizing, these fabrics deliver excellent matrix bonding and enhanced performance for structural laminates.

Key Benefits

• Multidirectional Strength – Provides reinforcement in both warp (0°) and weft (90°), perfect for marine hulls, decks, and structural panels.

• Robust Mechanical Properties – Ideal for high-impact and load-bearing applications, including boatbuilding and construction.

• Excellent Resin Wet-Out – Finely sized rovings enable efficient impregnation during hand lay-up, spray-up, infusion, and vacuum molding processes.

• Stable, Low-Fuzz Fabric – Engineered weave maintains integrity and minimizes loose fibers, ensuring cleaner laminates and easier handling.
