3-D spacer fabric construction is a newly developed concept. The fabric surfaces are strongly connected to each other by the vertical pile fibers which are interwoven with the skins. Therefore, the 3-D spacer fabric can provide good skin-core debonding resistance, excellent durability and superior integrity. In addition, the interstitial space of the construction can be filled up with foams to provide synergistic support with vertical piles.
The 3-D spacer fabric consists of two bi-directional woven fabric surfaces, which are mechanically connected with vertical woven piles. And two S-shaped piles combine to form a pillar, 8-shaped in the warp direction and 1-shaped in the weft direction.
The 3-D spacer fabric can be made of glass fiber, carbon fiber or basalt fiber. Also their hybrid fabrics can be produced.
The range of the pillar height:3-50 mm, the range of the width:≤3000 mm.
The designs of structure parameters including the areal density, the height and distribution density of the pillars are flexible.
The 3-D spacer fabric composites can provide high skin-core debonding resistance and impact resistance and impact resistance, light weight. high stiffness, excellent thermal insulation, acoustic damping, and so on.
