Abstract

The invention discloses a multilayer composite structure three-dimensional fabric and a preparation method thereof. The three-dimensional fabric comprises at least one structure unit composed of a three-dimensional weaving structure layer and at least one needling structure layer; each structure unit and two adjacent structure units are connected in a Z direction through a needling process; and the three-dimensional weaving structure layer is a 2.5 D structure layer, a three-direction orthogonal structure layer or a fine weaving puncture structure layer. According to the fabric, the 2.5 D, three-direction orthogonality, fine weaving puncture structure and needling structure are organically combined into the structure and function integrated composite material, the needling structure bears the mechanical properties of heat insulation and heat preservation performance of the material, and the weaving structure bears the mechanical properties of high specific strength, high specific modulus, impact resistance and the like of the material, so that the obtained composite material can meet the use requirements of the material, and rapid and low-cost production can be realized.

Description

technical field

[0001] The invention relates to the technical field of textiles, in particular to a three-dimensional fabric with a multilayer combined structure and a preparation method thereof. Background technique

[0002] The needle punching process is to use triangular or other shaped needles with barbs on the edges to repeatedly needle the fluffy fiber web. During the process, the fibers are entangled with each other, and under the action of friction, the fibers move up and down, and the fibers that produce up and down displacement squeeze the fiber net to a certain extent, so that the fiber net is compressed. The vertical "pin" state remains in the Z direction of the fabric, thereby forming a nonwoven with certain strength, density, elasticity and other properties; and through laminated needle punching, a three-dimensional prefabricated body with interlayer connections is formed. Needle-punched fabric has the characteristics of fast forming speed and low manufacturin...
