3-D Fiberglass Sandwich Woven Fabrics

Weave structure of our 3-D Fiberglass Sandwich Woven Fabric

Above: Woven structure of 3-D Sandwich

3-D sandwich woven fabrics are made of 100% E-glass yarns, as well as carbon fiber, basalt fiber of other high performance fibers. Two deck layers bonded together by Z-piles to the specified height of 2-25mm.

When the fabric is impregnated with a thermoset resin, the fabric immediately absorbs the resin and due to the capillary forces of the Z-piles, the fabric rises to the preset height. Because the composite material is a kind of hollow integrated core sandwich structure that offers excellent mechanical properties and design-versatility.

The composite material is widely used for many applications in the core composites industry, such as ships, railways, automotive, aviation, wind energy, double wall tanks and construction, while offering multiple advantages (delamination, impact etc) against traditional sandwiches such as honeycombs, foams, balsa, and more.
