The present application discloses a method and device for generating a jacquard pattern, an electronic device. The method comprises: acquiring structure information of a unit structure of a preform to be prepared, wherein the structure information comprises a positional relationship between the warp yarns and the weft yarns of the unit structure of a preform to be prepared; obtaining a row number and a column number of the jacquard pattern to be generated, and correspondence between each pixel in the jacquard pattern to be generated and the warp yarns and weft yarns of the unit structure of the preform to be prepared, according to the structure information; and obtaining a pixel value of each pixel according to the correspondence and the positional relationship between the warp yarns and the weft yarns, and generating the jacquard pattern to be generated.

Method and device for generating jacquard pattern, electronic device and readable storage medium

A method and a device are used for generating a jacquard pattern of a preform. The method comprises acquiring initial structure information of a preform to be prepared; generating an initial jacquard pattern of the preform to be prepared; pixel values of pixels in the initial jacquard pattern, comprising a first pixel value and a second pixel value, are equal to the first pixel value when warp yarns corresponding to the pixels are located above corresponding weft yarns, and are equal to the second pixel value when warp yarns corresponding to the pixels are located below corresponding weft yarns; acquiring yarn reduction information of the preform to be prepared; and adjusting the initial jacquard pattern according to the yarn reduction information to obtain the jacquard pattern of the preform to be prepared.

The present invention relates to a three-dimensional woven hollow layer-connecting fabric, comprising an upper layer-surface () formed by crossing upper ground warp yarns (), () and a weft yarn () and a lower layer-surface () formed by crossing lower ground warp yarns (), () and a weft yarn (); the weft yarns () and () on the upper and lower layer-surfaces are also crossed with poil warps (), () besides ground warp yarns (), () and (), () on their own layer-surface; the spatial walking direction of poil warps (), () woven from one layer-surface to another is opposite to the weft-inserting direction of the fabric. The framework feature of the composite layer-connecting fabric of the present invention is distinct, and the vertical support function of poil warps between two layer-surfaces is good. The spatial structure of the layer-connecting fabric is varied in conformation, easy to design and adapted to produce on a large scale. The compositely-strengthened material has the characteristics, such as anti-corrosion, anti-penetration, light weight and excellent physical mechanical properties.
