3D Spacer Fabric and Sandwich Construction

 

3d spacer fabric construction is a newly developed concept. Thefabric surfaces are strongly connected to each other by thevertical pile fibers which are interwoven with the skins.Therefore, the 3d spacer fabric can provide good skin-coredebonding resistance, excellent durability and superior integrity.In addition, the interstitial space of the construction can befilled up with foams to provide synergistic support with verticalpiles. These products have broad application prospects inautomobile, locomotive, aerospace, marine, windmills, building andother industries.

 

Product Characteristic

 

The 3D spacer fabric consists of two bi-directional woven fabricsurfaces, which are mechanically connected with vertical wovenplies. And two S-shaped piles combine to form a pillar, 8-shaped inthe warp direction and 1-shaped in the weft direction.The 3Dspacer fabric can be made of glass fiber, carbon fiber or basaltfiber. Also their hybrid fabrics can be produced.The range of thepillar height: 3-50 mm, the range of the width: 1200mm--3000 mm.Thedesigns of fabric structure parameters including the areal density,the height and distribution density of the pillar are flexible.3Dspacer fabric composites can provide high skin-core debondingresistance and impact resistance, light weight, high stiffness,excellent thermal insulation and acoustic damping, and so on.
