PROBLEM TO BE SOLVED: To obtain a woven fabric of flat yarn which is inexpensive, exhibits high strength characteristics, obviates such disadvantage as occurrence of voids, and is useful for fiber composite materials, etc., by using a specific flat yarn made of carbon fiber as the warp and the weft and weaving under specific conditions. SOLUTION: Using a twistless flat yarn of carbon fiber having a fineness of 3000 to 20000 denier, width of 4 to 16 mm and a ratio of width/thickness of >=30 as the warp Twr and the weft Twf, this woven fabric is fabricated at an inter-yarn space which is 1.0 to 1.2 times the thread width, basis weight of 100 to 300 g/m<2> , thickness of 0.1 to 0.4 mm and fiber density of >=0.8 g/cm<3> . Preferably, the warp Twr and the weft Twf have substantially no crimp. |
