Embodiment 1
[0019] Such as image 3 As shown, it is a three-dimensional schematic diagram of a curved variable cross-section step plate, which is woven with T700-12k carbon fiber. In the first step, according to the cross-sectional shape of the curved variable-section step plate, the arrangement form and the number of rows and columns of the yarn loading spindles on the chassis of the three-dimensional knitting machine are designed, and 360 knitting yarns are suspended to the load in an arrangement of 60 rows and 6 columns. On the yarn spindle; the second step is to adopt the four-step square three-dimensional weaving process. The first step is to make the knitting yarns of adjacent rows move alternately for one spindle distance along the row direction, and the second step is to make the knitting yarns of adjacent rows move along the column direction. Alternately move one spindle distance, the movement direction of the yarn in the third step and the fourth step is opposite to that of the ...

[0021] Such as image 3 As shown, it is a three-dimensional schematic diagram of a curved variable cross-section step plate, which is woven with T700-12k carbon fiber. The first step is to design the arrangement form and the number of rows and columns of the yarn loading spindles on the chassis of the three-dimensional knitting machine according to the cross-sectional shape of the curved variable-section step plate, and hang 2,880 knitting yarns in an arrangement of 120 rows and 24 columns. On the yarn spindle; the second step is to adopt the four-step square three-dimensional weaving process. The first step is to make the knitting yarns of adjacent rows move alternately for one spindle distance along the row direction, and the second step is to make the knitting yarns of adjacent rows move along the column direction. Alternately move one spindle distance, the movement direction of the yarn in the third step and the fourth step is opposite to that of the first step and the sec...
