3D Fiberglass Woven Fabrics (Sandwich Structure Fabrics)
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. These products have broad application prospects in
automobile, Locomotives, aerospace, marine, windmills, building and
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: ≤
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.
