Embodiment 1
[0034] First, design the meridional cross-sectional view of the self-bonding three-dimensional integral sandwich woven structure, and divide a meridional cross-sectional structure into circular segments consisting of one warp yarn of the upper plain weave and several weft yarns of the lower plain weave. The knotting section A that connects each layer of plain weave together by self-bonding and the sandwich section B that each layer is composed of an independent plain weave make the single-layer weft yarn that participates in the knotting in the single-layer plain weave of the knotting section A The number of threads is 1, the number of plain weave layers is 2, the number of weft yarns of the single-layer plain weave in the sandwich section B is 8, and the warp yarns of each layer that do not participate in the binding are marked with Arabic numerals, and the layers that participate in the binding are marked with Roman numerals Warp yarn, ○ represents weft yarn. refer to figu...
Embodiment 2
[0036] refer to Figure 4 and Figure 5 , the number of single-layer weft yarns participating in the binding in the single-layer plain weave of the joint section A is 1, the number of plain weave layers is 3, the number of weft yarns of the single-layer plain weave in the sandwich section B is 9, the first layer of plain weave and The second layer of plain weave interweaves the warp yarn II in the first layer of plain weave and the weft yarn 8 in the second layer of plain weave to complete the two-layer bonding. The second layer of plain weave and the third layer of plain weave The warp yarn I in the second layer plain weave and the weft yarn 7 in the third layer plain weave that participate in the bonding are interwoven to complete the two-layer bonding, thereby forming a three-layer plain weave three-dimensional integral sandwich woven structure. Others are the same as embodiment one.
Embodiment 3
[0038] refer to Figure 6 and Figure 7 , the number of single-layer weft yarns participating in the binding in the single-layer plain weave of the joint section A is 3, the number of plain weave layers is 4, the number of weft yarns of the single-layer plain weave in the sandwich section B is 7, the first layer of plain weave and The second layer of plain weave is joined by the warp yarn III in the first layer of plain weave participating in the bonding and the weft yarn 11 and weft yarn 19 in the second layer of plain weave interweaving to complete the two-layer bonding, the second layer of plain weave and the third layer of plain weave The two layers of plain weave are joined by the interweaving of the warp yarn II in the second layer of plain weave and the weft yarn 10 and weft yarn 18 in the third layer of plain weave that participate in the bonding. The third layer of plain weave and the fourth layer of plain weave The weaving is completed by the interweaving of the war...
