Abstract

The invention discloses a weaving method for a truncated cone-shaped fabric. The fabric comprises a warp system and a weft system, wherein the warp system and the weft system are mutually interwoven to a multi-layer angle-interlocking structure. The weaving method comprises the following steps: 1, initially arranging warps; 2, moving to drive the warps to form sheds; 3, introducing wefts; 4, adding warps; 5, secondarily moving to drive the warps to form sheds; 6, secondarily introducing the wefts; and 7, repeating the steps 4 to 6. The integral density uniformity of the fabric woven by the weaving method disclosed by the invention is remarkably improved; the performances at yarn adding points completely satisfy the design objective requirements according to the compounded performance test; and the technical problem that through holes are formed at the yarn adding points caused by the existing yarn adding process is solved. According to the weaving method disclosed by the invention, the whole-row yarn adding process structure is complete, the fibers are continuous, and the forming speed is high, thereby realizing two yarn adding technologies in a weaving process that a 2.5D woven structure is continuously increased with the increase of the diameter of the section of a truncated cone.

Description

technical field [0001] The invention relates to a preparation method of a truncated cone fabric. Background technique [0002] The weaving of the truncated cone fabric adopts the 2.5D weaving method. The 2.5D fabric and its weaving technology are a new type of three-dimensional fabric weaving technology that has developed rapidly in recent years. Brown silk makes warp yarns form multi-layer openings, and a kind of multi-layer three-dimensional fabric is formed after introducing weft yarns in a certain order. In 2.5D fabrics, the weft yarns are basically in a straight state, and the warp yarns bend through adjacent weft yarn layers to form a layer-by-layer shallow-linked fabric structure. [0003] At present, composite reinforced fabrics with conical profiles are mostly manufactured by integral weaving. The reinforced fabric manufactured by the integral weaving method has good integrity and uniform fiber distribution, and the composite material made of it has excellent mech...
