The 7781 Fiberglass Cloth is a high-quality E-glass woven fabric designed for applications requiring superior mechanical strength, excellent dimensional stability, and precise fabric consistency. Its smooth surface and 8H satin weave structure ensure excellent drapability and resin flow, making it ideal for high-performance composite laminates.
Widely used in aerospace, automotive, industrial, and electronics applications, 7781 Fiberglass Cloth delivers reliable durability and ease of processing for both manual and automated lay-up methods.
Warp strength >150 lbs/inch and fill strength >130 lbs/inch for reinforced composites.
Consistent satin weave ensures smooth resin flow and minimal voids.
8H satin weave provides superior flexibility and lay-up precision.
Maintains flatness and shape during processing and curing.
E-glass fibers offer high resistance to heat and chemicals.
