Abstract

The invention discloses a synchronous heterodromous three-dimensional fabric of a 2.5D braided structure and a preparation method thereof. The synchronous heterodromous three-dimensional fabric comprises a columnar fabric, the top part of the columnar fabric is sealed or not sealed, and the bottom part of the columnar fabric is provided with an outer flanging; the outer flanging comprises a vertical flanging and an inclined flanging, the vertical flanging means a flanging which is vertical to a certain side of the columnar fabric, and the inclined flanging means a flanging which is not vertical to the certain side of the columnar fabric; the preparation method comprises the steps of knitting by taking a mandrel as an inner core, and adopting a 2.5D curved shallow-crossing linking knitting unit structure. According to the preparation method of the synchronous heterodromous three-dimensional fabric of the 2.5D braided structure provided by the invention, the integral forming of the fabrics with more complicate shapes can be realized; furthermore, a prepared fabric unit is complete in structure and good in fiber continuity; meanwhile, a complete unit structure has a strong designability in the fabric forming process; in addition, fibers of 2.5D braided structures have more weaving points, and the unit structure is low in degree of freedom, controllable in process parameters and good in structural uniformity; finally, the obtained fabric is compact in structure, good in integrality and excellent in mechanical property.

Description

technical field [0001] The invention relates to a synchronous anisotropic three-dimensional fabric with a 2.5D weaving structure and a preparation method thereof, belonging to the field of three-dimensional fabrics. Background technique [0002] 2.5D fabric is a kind of multi-layer three-dimensional fabric formed on the basis of woven three-dimensional weaving equipment, using multi-eye brown silk to make warp fibers form multi-layer openings, and introducing weft fibers in a certain order, but currently 2.5D fabrics The three-dimensional braided fibers have fewer interweaving points, the degree of freedom of unit structure change is large, and the design of structural process parameters is affected by many factors due to unit structure changes, the process parameters are uncontrollable, and the structure uniformity is poor. It is urgent to develop a new 2.5D product. At present, there is no related report on synchronous three-dimensional fabric with 2.5D weaving structure....
