Build ultimate torsional and shear strength into your composite parts with our DBM 45/45 2408 Double Bias Mat. This exceptionally heavy-weight E-glass fabric features fibers precisely oriented at +45 and -45 degrees, delivering maximum off-axis reinforcement crucial for parts subjected to the most severe twisting and shearing forces.

The “2408” style combines a very heavy 24 oz/yd² double bias layer stitched securely to a lightweight (~0.8 oz/ft²) chopped strand mat (CSM) backing. This robust construction offers unparalleled advantages:

• Extreme Shear & Torsional Strength:The highly effective +/- 45-degree fiber orientation, combined with significant material weight, provides the highest degree of resistance to twisting and shearing loads for critical structural applications.
• Rapid & Substantial Bulk:The very heavy combined weight builds laminate thickness extraordinarily fast, minimizing the number of layers required for massive and strong structures.
• Superior Handling for Heavy Materials:The integrated CSM backing significantly aids in handling, cutting, and positioning this heavy fabric, preventing excessive fraying and facilitating faster, more efficient lay-up, even with such substantial material.
• Enhanced Resin Absorption & Bonding:The mat backing creates an optimal resin-rich interface, ensuring excellent adhesion between plies, aiding in rapid and thorough wet-out, and effectively preventing print-through on thicker laminates.
• Broad Resin Compatibility:Engineered for seamless integration with Polyester, Vinyl Ester, and Epoxy resin systems, offering versatility for the most demanding project requirements.

Perfect for the most rigorous applications requiring maximum torsional stiffness and shear resistance, such as heavy-duty boat hulls (especially transoms, bulkheads, and high-stress areas), large-scale industrial components, wind turbine structural elements, and any FRP fabrication where ultimate off-axis strength and rapid bulk build-up are paramount.
