Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings, but it should not be understood that the scope of the above-mentioned theme of the present invention is limited to the above-mentioned embodiments.

[0020] Such as figure 1 As shown, a mixed yarn bundle is formed by connecting a carbon fiber bundle 1 and a quartz fiber bundle 2 in series, and is used as a single yarn bundle after being connected. A 2.5D seamless butt joint flat fabric overall weaving method, in the weaving process, the warp direction yarns in the 2.5D flat weaving area are segmented to select different special fibers for series connection, so that different yarns are connected in pairs to form long yarn bundles, and used at the same time The formed mixed yarns are used as warp yarns for fabric weaving, and the required special fiber yarns are selected as weft yarns for overall weaving and molding. Using this method of weaving is conducive to ...

Abstract

The invention relates to the textile technology, in particular to an integral weaving method for flat fabric. The integral weaving method for 2.5D seamless joint flat fabric comprises the steps that in the weaving process, different special fibers are selected in a segment mode for warp yarns in 2.5D flat weaving areas to carry out serial connection, and every two different yarns are connected to form a long yarn bundle; meanwhile, formed hybrid yarn bundles serve as fabric weaving warp yarns, and needed special fiber bundles are selected to serve as weft yarns to carry out integral weaving formation. By carrying out weaving in the mode, integral formation of different fiber weaving segments can be promoted, and different fibers meeting the performance can be arranged in the 2.5D flat areas respectively; meanwhile, the integrity of fabric is not influenced, the continuity of the integral structure of a prefabricated body is ensured, and the strength of the prefabricated body is also considered.

Description

technical field [0001] The invention relates to a weaving process, in particular to a method for integral weaving of flat fabrics. Background technique [0002] The 2.5D flat fabric woven with special fibers such as carbon fiber and quartz fiber is a fiber-reinforced prefabricated body for various composite nozzles, throat linings and combustion chambers. It has excellent properties such as high strength modulus, small thermal deformation, low density, erosion resistance and friction resistance, and is widely used in solid rocket motor nozzle ablation composite materials. According to different application occasions and different performance requirements, many fiber-reinforced prefabricated bodies need to use composite materials with different properties to be braided and then spliced. However, the splicing of a certain number of preforms destroys the integrity of the yarn, affects the continuity of the overall structure of the preform, reduces the strength of the preform, ...
