Woven Roving Fiberglass 24oz with 1.5oz Chopped Strand Mat • 61-Yard Roll • 76" Width

This combo reinforcement integrates 24oz woven roving with a 1.5oz chopped strand mat (CSM) that is stitched to the roving—no brittle, styrene-only binder—so it wets out easily and is compatible with polyester, vinyl ester, and epoxy systems. The woven roving provides high biaxial strength and stiffness, while the mat improves interlaminar bonding, reduces print-through, and allows rapid laminate build for strong, smooth, and durable parts. Supplied in a 76 inch (193cm) width on a 61-yard (55.8 m) roll.

Key advantages

• Fast build rate: Heavy 24oz roving plus 1.5oz mat delivers thickness and stiffness quickly, reducing ply count and layup time.
• Stronger laminates: Woven roving provides high tensile and flexural strength in 0/90°, while the CSM improves shear and interlaminar properties.
• Smoother surfaces: Mat layer helps mask roving print and creates a better substrate for gelcoat and finishing.
• Reliable wet-out: Stitched construction (no dissolved binder) promotes excellent resin flow for hand layup and infusion-assisted processes.
• Labor-saving combo: Pre-combined roving and mat reduce cutting and stacking steps, speeding production.
• Wide format: 76" width covers large areas efficiently for hulls, decks, and molds.

Typical uses

• Boat hulls, decks, stringers, transoms, and bulkheads.
• Tooling and molds requiring fast thickness build and smooth surfaces.
• Panels, fairings, covers, and general industrial laminates.
• Structural repairs and reinforcement where 0/90° strength with improved interlaminar bonding is required.

Processing notes

• For hand layup, wet out the mat side first to promote interlaminar bond, then finish through the roving side.
• Use consolidating rollers to remove entrapped air and ensure uniform resin distribution.
• Stagger seams between plies to avoid hard lines and concentrate joints away from high-stress regions.
• Suitable for hand layup, spray-up, and assisted infusion with appropriate flow media and strategy.
• Follow resin supplier cure schedules; post-cure if required by the resin system.

We sell this fabric by the linear yard. You will receive a continuous piece of fabric at the width listed.

For example, if the fabric is 50" wide, a quantity of 1 (linear yard) equals a continuous piece measuring 50" wide × 36" long. A quantity of 5 (linear yards) equals a continuous piece measuring 50" wide × 180" long.
