3D Sandwich Glass Woven Fabrics

Pioneer work with Nantong University to develop 3D woven technical textile for industrial application. 3D sandwich glass 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 thermostat 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. Features: Light weight and higher stiffness The composite weight is only 30%-60% lighter chopped strand mat and glass roving fabrics of the same thickness. Simple and effective lamination process. 3D glass fabric is time and materials saving, which can be made in one step to achieve the thickness(10/15/20mm) because of its integral sandwich structure. Outstanding performance of anti-delaminating 3D glass consists of two layers of yarns bonded by vertical piles yarn, which were woven into the deck layers. In that way, the integral sandwich structure will be made. Easy to make an angle curve. One advantage of 3D Glass woven fabric composite is very easy to be shape-able. It can easily  conform around the contoured surfaces. Hollow structure Space between two layers of deck would be multi-functional. For example, it can be used to monitor the leakage by embedded with sensors or wire.
