概述
The unidirectional stitched mat at 450g/m² concentrates its fibers along a single 0° axis and is engineered for wind energy pultrusion, where reinforcement is pulled continuously through a heated die to form constant-section profiles such as blade spar caps. Aligning the fibers in one direction maximizes strength and stiffness along the profile, exactly where pultruded structural members carry their load.
The stitched, non-crimp construction keeps the unidirectional fibers straight and parallel so they deliver their full mechanical potential, while light cross-stitching holds the fabric together for stable feeding through pultrusion tooling. At 450g/m² the mat provides efficient single-axis reinforcement without excess weight.
Made from E-glass, alkali-free fiber, the mat offers chemical resistance and consistent properties suited to long-life wind energy components. It integrates into pultrusion lines running polyester, vinyl ester, or epoxy resins.

常见问题
Why is unidirectional reinforcement used in pultrusion?
Pultruded profiles such as spar caps carry load along their length, so aligning fibers in the 0° direction maximizes strength and stiffness exactly where it is needed, using material efficiently.
How does the mat feed through pultrusion tooling?
Light cross-stitching holds the straight unidirectional fibers together, keeping the fabric stable so it feeds smoothly and consistently through the heated pultrusion die.
What weight is the unidirectional stitched mat?
It is a 450g/m² mat, providing efficient single-axis reinforcement for wind energy pultrusion without adding excess weight.
