Product Description
3D Spacer fabric and sandwich construction
3D spacer fabric construction is a newly developed concept. The fabric surfaces are strongly connected to each other by the vertical pile fibers in the core, which are interwoven with the skins. Therefore, the 3D 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. These products have broad application prospect in automobile, locomotive, aerospace, marine, windmills, building and other industries.
Product Characteristics:
The 3D spacer fabric consists of two bi-directional woven fabric surfaces, which are mechanically connected with vertical woven plies. And two S-shaped piles combine to form a pillar, 8shaped in the warp direction and 1shaped in the weft direction.
The 3D 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: 1200mm to 3000 mm.
The designs of fabric structure parameters including the areal density, the height and distribution density of the pillar are flexible.
3D spacer fabric composites can provide high skin core debonding resistance and impact resistance, light weight, high stiffness, excellent thermal insulation and acoustic damping, and so on
