Biax 300 ±90° Glass Fabric

Allbase Biax glass cloth is a composite reinforcement fabric made of two layers of continuous E-glass fibres stitched at ±90° angles. The orthogonal structure offers balanced strength in both the longitudinal and transverse directions, making it especially suitable for applications subjected to tensile loads in both directions across a laminate.

The ±0°/90° fibre orientation provides the fabric with balanced mechanical performance in both the length and width directions. Longitudinal layers at 0° offer high tensile strength in the direction of the weave, while transverse layers at 90° contribute strength across the cross-section. This balanced reinforcement structure helps composite laminates withstand multi-directional loads more evenly than single-direction or random mat reinforcements.

Because the fibres are arranged in straight, non-crimp layers and lightly stitched rather than woven, the fabric retains good permeability and wet-out characteristics with common resin systems, including Vinylester, Epoxy and Polyester resins. The lack of heavy interlacing also makes the cloth easier to handle and conform to simple contours during lay-up.

Compatible with various laminating techniques, this cloth is ideal for structural work, panel construction, boat components, sporting goods, and other composite parts that require balanced in-plane strength and stiffness.
