A method for manufacturing solid structural material using a three-dimensional five-axial woven fabric. In weaving a three-dimensional five-axial woven fabric W using a three-dimensional weaving machine, divisibly woven sections are formed in portions of a manufactured three-dimensional five-axial woven fabric by alternately driving an upper and a lower insertion members for inserting a vertical yarn from above and below, respectively, in such a manner that each of the insertion members and a weft insertion rapier are driven with different timings.

A method for manufacturing a solid structural material using a three-dimensional five-axial woven fabric W. In weaving a three-dimensional five-axial woven fabric W using a three-dimensional weaving machine, divisibly woven sections S are formed in portions of a manufactured three-dimensional five-axial woven fabric by alternately driving upper and lower insertion members for inserting a vertical yarn Z from above and below, respectively, in such a manner that each of the insertion members and a weft insertion rapier are driven with different timings.

A three-dimensional weaving machine that enables biased yarn guide blocks to be reduced in size and their movement to be simplified and that reliably feeds biased yarns is described. A three-dimensional mechanism contains 2N guide blocks (13), each including a biased yarn through-hole (15) extending along the length direction. A guide block receiving and supporting device (18) forms guide block arrangement spaces (S1), (S2), and (S3) in a bottom stage, a middle stage, and a top stage wherein N of the 2N guide blocks can be arranged in each stage parallel with, and adjacent to, one another. A guide block moving device (22) is provided for moving the guide blocks in each stage in opposite directions along the respective stages, and a shifting device (44) operates for simultaneously shifting two adjacent sets of guide blocks movably arranged in the respective guide block arrangement spaces, each by one stage.
