Biaxial fabric consists of two layers stitched together, with their fibre strands lying at +/- 45 degrees to the edges (instead of along the roll and across at 90 degrees, as with plain weave fibreglass fabrics). For example, the +/- 45 biaxial weave cloth is 17 oz. per square yard, and the mat backing is 8 oz. per square yard, so the total weight is 25 oz. per square yard.
Please note: 18 oz. biaxial weave fibreglass cloth is sold by the yard; 17 oz. cloth is sold in three pre-cut lengths. All types have a 3/4 oz. mat backing that adds extra thickness and ensures a smoother finished surface.
Features
- Biaxial fabric requires less resin, and conforms easily
- Flat, non-crimped fibres result in less print-through and greater stiffness than woven fabrics.
