Process for weaving three-dimensional fabrics with special-shaped cross-section and special-purpose heald wire

Abstract

This invention involves manufacture craft of one kind of three dimensional fabric with heterogeneous type section and its special-purpose synthesis silk. This synthesis silk can be manufactured by three dimensional loom equipment. Harness wire in raise synthesis installment's harness frame to process the special multi- eyes synthesis silk. The warp thread arrangement on the multi- eyes synthesis silk is based on the heterogeneous type section implementation craft. According to the specific harness frame movement procedure, let the warp thread to form the multilayered aperture. According to the certain sequence introduction weft, realization fabric structure taking shape. This invention use the multi- eyes synthesis silk to realize the multilayered fabric structure to take shape, using the multilayer achieved the fabric thickness need, enable the fabric to have the certain thickness and the lateral section shape, the fabric overall performance strong, the fabric size profiling precision was high; In weaves process to progress the good warp thread arrangement according to the heterogeneous type section size need passable different harness frame fluctuation procedure in the multi- eyes synthesis silk, forms the multi-level clear aperture easy multilayer filling insertion to weave, fabric dimension control scope bigger, the fabric weaves the process to be possible operational to be strong, may process the many kinds of heterogeneous types section fabric.

Description

technical field [0001] The invention relates to a weaving process for weaving three-dimensional fabrics with special-shaped cross-sections and special heddles, and belongs to the technical field of three-dimensional fabric weaving. Background technique [0002] The engineering research of woven three-dimensional technology in my country began in the 1990s, and woven three-dimensional fabrics are widely used in aerospace and aviation fields, especially in the field of military weapons. As the reinforcing substrate of composite materials, the function of fabrics is developing from singleness to multifunctionality. However, the weaving process of weaving three-dimensional fabrics with special-shaped cross-sections is still blank in the research and application fields of our country. The three-dimensional multi-layer fabric proposed by Chinese patent application CN-1182813A has few fabric layers and a single structure, and cannot weave thick fabrics with complex shapes, while t...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the woven three-dimensional fabric woven by the prior art has fewer layers, a single structure, cannot weave complex thick fabrics, and has certain limitations in thickness, and provides a special-shaped section woven fabric for the society. Three-dimensional weaving process technology, which can effectively weave the reinforced substrate of various composite materials with special-shaped cross-sections
