Build stronger, more torsionally rigid composite parts with our DBM 45/45 1708 Double Bias Mat. This high-quality E-glass fabric features fibers oriented at +45 and -45 degrees, providing outstanding off-axis reinforcement crucial for parts subjected to significant twisting and shearing forces.

The “1708” style combines a heavy 17 oz/yd² double bias layer stitched securely to a lightweight (~0.8 oz/ft²) chopped strand mat (CSM) backing. This construction offers several advantages:

• Superior Shear & Torsional Strength:Fibers at +/- 45 degrees are highly effective at resisting twisting and shearing loads, making this ideal for high-stress structural applications.
• Rapid Bulk & Efficient Lay-up:The combined heavier weight builds thickness quickly, allowing for fewer layers to achieve significant structural bulk.
• Improved Handling for Heavier Fabrics:The CSM backing makes this heavier fabric easier to handle, cut, and position, significantly reducing fraying and speeding up the laminating process.
• Enhanced Bonding & Print-Through Prevention:The mat provides a resin-rich layer that promotes excellent adhesion between plies, ensures thorough wet-out, and helps prevent print-through on the finished part.
• Versatile Compatibility:Suitable for use with Polyester, Vinyl Ester, and Epoxy resin systems.

Ideal for demanding applications requiring robust off-axis reinforcement and quick build-up, such as heavy-duty boat hulls and decks (especially stringers, bulkheads, and reinforcement around high-stress areas), structural components in marine and automotive industries, wind turbine blades, and any FRP fabrication where high torsional stiffness and shear resistance are paramount.
