Biaxial Fibreglass Mat 400gsm 600gsm ±45° Structural Cloth

Stitched Biaxial Fibreglass Reinforcement for High Strength Composite Laminates

Biaxial Fibreglass Mat is a high performance stitched reinforcement designed for structural composite laminates where strength, efficiency and reliability are critical. Available in 400gsm and 600gsm either per metre or roll, this ±45° biaxial fabric delivers superior load distribution and laminate strength compared to traditional chopped strand mat.

Constructed with continuous fibres stitched in opposing ±45° orientations, this material provides excellent shear strength and multi-directional reinforcement. Unlike chopped strand mat, there is no binder present, allowing for improved resin penetration, faster wet-out and reduced resin consumption. This results in stronger, lighter laminates with better fibre-to-resin ratios.

Biaxial fibreglass is widely used in marine construction, automotive fabrication and industrial composites where structural integrity is essential. It conforms well to curves and complex moulds while maintaining fibre alignment, making it ideal for both new builds and repair work. Use 400gsm for easier handling, ideal for layering and complex shapes while 600gsm is higher strength and faster laminate build-up.

This material is compatible with polyester, vinyl ester and epoxy resin systems, making it a versatile reinforcement option for a wide range of composite applications.
