Carbon fiber woven fabric, its weaving method and weaving apparatus

Abstract

A carbon fiber woven fabric which uses a flat carbon fiber yarn consisting of many carbon fibers as at least its warp or weft, its weaving method and weaving apparatus. The flat carbon fiber yarn is twist-free, the number of its carbon fibers being 6,000 to 36,000, the yarn size being 3,000 to 30,000 deniers, the yarn width being 4 to 16 mm, the yarn thickness being 0.07 to 0.6 mm, and the ratio of yarn width to yarn thickness being 20 to 150. In the carbon fiber woven fabric, the flat carbon fiber yarn has a yarn width of 4 to 16 mm, a yarn thickness of 0.07 to 0.6 mm, a ratio of yarn width to yarn thickness of 20 to 150, and a ratio of weaving yarn pitch to yarn width of 1.0 to 1.2, the thickness of the woven fabric being 0.1 to 0.6 mm, the weight of woven fabric being 90 to 500 g/m.sup.2 and the fiber density of woven fabric being 0.8 to 1.2 g/cm.sup.3. The woven fabric is woven by a weaving apparatus provided with at least a weft supply device or a warp supply device.
