概述
Multiaxial fiberglass fabric places fibers at ±45° to provide high shear strength, and at 300g/m² in A-grade, alkali-free construction it is engineered for wind turbine nacelle covers and structural FRP. Unlike a woven fabric, the layers are stitched together rather than crimped over one another, so the fibers remain straight and deliver their full mechanical potential.
The ±45° biaxial orientation makes the fabric particularly effective at resisting shear and torsional loads, which is why it is specified for nacelle covers and panels that experience complex loading. The stitched, non-crimp construction also improves resin flow and produces laminates with higher and more predictable strength than equivalent woven fabrics.
Used in wind energy, nacelle covers, and structural applications, the fabric suits resin infusion and other closed-mold processes common in large composite manufacturing. It is compatible with polyester, vinyl ester, and epoxy resins.

常见问题
What is the advantage of ±45° fiber orientation?
The ±45° orientation gives the fabric high shear and torsional strength, making it well suited to nacelle covers and panels that experience complex loading.
How does multiaxial fabric differ from woven cloth?
The layers are stitched rather than crimped over one another, so the fibers stay straight. This delivers higher, more predictable strength and improved resin flow compared with woven fabric.
What does A-grade alkali-free mean?
A-grade alkali-free indicates a high-quality E-glass composition with low alkali content, providing good chemical resistance and consistent mechanical performance for demanding structural use.
