The electromagnetic guide block of the patent is not in direct contact with the bottom plate, so that the friction force is reduced. However, the oblique yarn introducing mechanism in the patent is easy to be adhered to yarns in other directions, so that the finally manufactured composite material is not uniform enough in the interior, not smooth enough on the surface and greatly reduced in mechanical property.
The invention patent with the application number of 'CN 201710455564.8', named as 'a multi-shaft three-dimensional weaving machine combining weaving and knitting' discloses a multi-shaft three-dimensional weaving machine combining weaving and knitting, which realizes the surface of a woven three-dimensional orthogonal fabric by utilizing the weaving machine, realizes the surface of the woven three-dimensional orthogonal fabric by utilizing the weaving machine, and forms a three-dimensional knitting fabric consisting of three groups of oblique yarns by utilizing an oblique yarn weaving machine to realize the tight combination of the surface layer weaving and the middle core layer weaving of the multi-shaft three-dimensional fabric.
