The 320g Biaxial Glass Cloth is a versatile reinforcement material engineered for high-performance composite applications. Unlike traditional woven fabrics, this biaxial cloth is made by stitching layers of glass fibers oriented at +45° and -45°, providing exceptional strength and stiffness in two directions. Weighing 320 grams per square meter, this fabric offers a robust yet manageable solution for creating lightweight, high-strength laminates. With a width of 1270mm, it provides broad coverage, reducing seams and overlaps, making it ideal for large-scale projects.

This material is widely used in industries such as marine, wind energy, and aerospace, where its biaxial orientation enhances mechanical properties in laminates, particularly in shear and torsional strength. When combined with resins like epoxy, polyester, or vinyl ester, the fabric forms a durable composite structure capable of withstanding significant loads and environmental stress. The stitched construction eliminates crimping, which is common in woven fabrics, improving load distribution and maximizing strength retention.
The 320g Biaxial Glass Cloth is not only strong but also easy to handle. Its flexible nature allows it to conform to complex shapes and curves, making it suitable for intricate designs and custom parts. Additionally, its compatibility with vacuum infusion, hand lay-up, and resin infusion processes ensures versatility across various fabrication methods. Whether for constructing hulls, wind turbine blades, or structural reinforcements, this fabric offers a reliable and efficient solution for demanding composite applications.
