3D sandwich woven fabric canbe make of E-glass fibers as well as other high-performance fibers.The fabrics consists of two deck layers bonded together by vertical piles ranging from 2mm to 40mm.

There are many weaving ways,such as "o" shape, "v"shape, "w"shape and "口" shape etc,one of the most typicals is "x" shape. This product can be woven with high-performance fiber and the height is from 2-30mm and formed many series.There are many ways to design this producr including woven density ,height,the thickness of the surface layer and the distance between the velvets etc. The high-performance complex material with good dynamical performance offerde new reinforcing base material for the developing of the high-performance complex material in China. The special fabric with parallel beam structure is widely used in aviation,aerospace,
shipbuilding,petrochemical underground storage containers,building materials,apores equipment transportaion and other fields because of its good features.
