450gsm double bias fibreglass mat ±45° in 1270mm full rolls. High strength reinforcement for marine, composite and structural laminates.

450gsm ±45° Double Bias Fibreglass Cloth for Structural Composite Laminates

Double Bias Fibreglass Mat 450gsm is a stitched reinforcement fabric designed for high strength composite laminates in marine, automotive and industrial applications. Supplied in full rolls with a width of 1270mm and total roll weight of approximately 50kg, this material is ideal for large scale laminating and structural reinforcement work.

Constructed with continuous fibres stitched in a ±45° orientation, double bias mat provides excellent shear strength and multi-directional load distribution. This fibre alignment allows the laminate to better handle stress and movement compared to traditional chopped strand mat, making it a preferred choice for structural applications.

Unlike chopped strand mat, double bias fabrics contain no binder, allowing for improved resin penetration, faster wet-out and more efficient fibre-to-resin ratios. This results in stronger, lighter laminates with improved performance characteristics.

Compatible with polyester, vinyl ester and epoxy resin systems, this 450gsm double bias mat is widely used in boat building, composite fabrication and reinforcement applications where strength, consistency and efficiency are critical.

Features & Benefits

Key Features

  • 450gsm stitched double bias fibreglass reinforcement

Double Bias Fibreglass Mat 450gsm Full Roll 1270mm Width FAQs

What is Double Bias Fibreglass Mat 450gsm Roll used for?

Double Bias Fibreglass Mat 450gsm Roll is used for structural reinforcement in composite laminates where high strength, impact resistance, and effective load distribution are required.

What does ±45° mean in Double Bias Fibreglass Mat 450gsm Roll?

The ±45° designation refers to fibres stitched diagonally in two opposing directions, improving shear strength, torsional resistance, and multi-directional structural performance.

Is Double Bias Fibreglass Mat 450gsm Roll stronger than chopped strand mat?

Yes, Double Bias Fibreglass Mat 450gsm Roll provides significantly greater strength, stiffness, and structural performance than chopped strand mat due to its continuous fibre orientation and engineered reinforcement design.

What resin systems can be used with Double Bias Fibreglass Mat 450gsm Roll?

Q4. A: Double Bias Fibreglass Mat 450gsm Roll is compatible with polyester, vinyl ester, and epoxy resin systems, making it suitable for a wide range of composite fabrication applications.

What is the roll length of Double Bias Fibreglass Mat 450gsm Roll?

Roll length can vary depending on the manufacturer. As a guide, a 50kg roll of 450gsm Double Bias Fibreglass Mat is typically around 85–90 metres in length. Always confirm the exact roll length with the supplier.

Can Double Bias Fibreglass Mat 450gsm Roll be used on curved surfaces?

Yes, Double Bias Fibreglass Mat 450gsm Roll conforms well to curves, contours, and complex shapes while maintaining excellent fibre strength and structural reinforcement properties.
