ABSTRACT:
A spirally woven fabric as well as a prepreg and a rotary body each using the fabric therein is adapted for use as materials for high-speed rotary bodies such as flywheels for electric power storage. The fabric composed of interwoven warps and wefts is such that its warps are arranged in a spiral direction, and the warps positioned more outside in the radial (weft) direction have a higher specific elastic modulus in the warp direction than those positioned more inside in the radial direction whereby a rotary body made of the fabric is enabled to be rotated at a higher rotating speed without breakage of the wefts and consequent peeling-off between the warps.
