3D Spacer Fabric and Sandwich Construction

3D spacer fabric construction is a newly developed concept. The fabric surfaces connected with each other stronglly vertical pile fibers which are interwoven with surfaces, and the weaving technique has its own intellectual property rights. Therefore, 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 foam to provide synergistic support with vertical piles, and be a new sanwich construction composites.These products have broad application in automobile, locomotive, building, marine, aerspace, shipbuilding, energy and other industries.

Structure characteristics: 3D 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-sharped in warp direction and 1-sharped in weft direction.

Applied fiber: glass fiber, carbon fiber, basalt fiber and also synthetic fabric.

Standard specifications: the range of piller height is 3-50mm, the range of width≤1270mm.

The design of structure parameters including areal desity, height and distribution density of the pillars are all flexible.

The 3D spacer fabric composites can privide high skin-core debonding resistance and impact resistance, light weight,high stiffness, excellent thermal insulation, acoustic damping and so on.

3D braided irregular fabrics and composites

3D barided irregular fabrics and composites have a distinct structure which is a fully integrated, continuously spatial fiber network. The new innovative composites put an end to low interlaminar strengths in laminated materials. Due to their excellent mechanical properties, such as delamination resistance and impact damage tolerance, 3D barided irregular fabrics and composites have potentian applications in the aerospace, automobile, marine and biomedical industries.

3D braided irregular fabrics have a distinct structure that is a fully continuous and multidirectional yarn network;

Design flexibility: it is feasible to produce a wide variety complex near-net-shape performs;

3D braided irregular fabric composites have excellent properties including high strength and stiffness, perfect damage tolerance and impact resistance.

3D braided irregular composites with complex shape can be inexpensive and simple to manufacture.
