중공형 원반직기의 제직메카니즘에 대한 연구(I) -직기제작과 경사장력의 이론적 고찰- = Studies on the Weaving Mechanism of Hollow Circular Disk Looms(I) -Loom Manufacture and Theoretical Analysis of Warp Tension-

다국어 초록 (Multilingual Abstract)

In the fiber reinforced composite field, it is important to develop a hollow circular disk weaving(HCDW) loom for the manufacture of special shaped woven fabrics having axisymmetrical properties. The weaving principle of the HCDW loom is that warp yarns are arranged radially from the center and weft yarns are inserted spirally between the warp yarns. Also, a unique characteristic of HCDW loom is the two-phase shedding motion with circular motion of a cam. In this paper, the weaving mechanism of the newly designed HCDW loom is described and the variation of warp tension during shedding motion is theoretically analyzed. The results have been compared with the experiment by attachment of a warp tension compensator for the determination of optimum weaving condition.
