Build composite parts with enhanced torsional and shear strength using our DBM 45/45 1208 Double Bias Mat. This high-quality E-glass fabric features fibers oriented at +45 and -45 degrees, providing excellent off-axis reinforcement crucial for parts subjected to twisting and shearing forces.

The “1208” style combines a 12 oz/yd² double bias layer stitched securely to a lightweight (~0.8 oz/ft²) chopped strand mat (CSM) backing. This construction offers several advantages:

• Exceptional Shear & Torsional Strength:Fibers at +/- 45 degrees are ideal for resisting twisting and shearing loads, which are common in many structural applications.
• Rapid Bulk & Coverage:The combined weight builds thickness efficiently, allowing for faster laminate build-up compared to biaxial fabrics alone.
• Improved Handling:The CSM backing makes the fabric easier to handle, cut, and position without excessive fraying, particularly beneficial for bias fabrics.
• Enhanced Bonding:The mat provides a resin-rich layer, promoting excellent adhesion between plies and helping to prevent print-through, ensuring a solid, cohesive laminate.
• Versatile Compatibility:Suitable for use with Polyester, Vinyl Ester, and Epoxy resin systems.

Ideal for applications requiring superior off-axis reinforcement and efficient lay-up, such as boat hulls and decks (especially stringers, bulkheads, and reinforcement around openings), wind turbine blades, automotive chassis components, and any FRP fabrication where torsional stiffness and shear resistance are critical.
