SCREW COMPONENT FORMED OF TWO-DIMENSIONAL CARBON/CARBON COMPOSITE MATERIAL COMPRISING STACKED ANISOTROPIC NONWOVEN FABRICS
To provide: a screw component formed of a two-dimensional carbon/carbon composite material, the screw component achieving high strength by enhancing a degree of contribution of carbon fibers to strength of the screw component; and a screw component formed of a two-dimensional carbon/carbon composite material, the screw component being protected from breakage by relaxing thermal stress generated therein due to a large change in an ambient temperature where the screw component is used, and being capable of reducing loosening of a screw-fastened part.SOLUTION: The present invention provides a screw component formed of a two-dimensional carbon/carbon composite material which is produced by stacking anisotropic nonwoven fabrics that use short carbon fibers, the screw component having a configuration wherein a central axis direction of the screw component is oriented so as to coincide with a Y direction (a direction in which fewer short carbon fibers are oriented) of the two-dimensional carbon/carbon composite material having anisotropy.SELECTED DRAWING: Figure 3
【課題】ネジ部品の強度に対する炭素繊維の寄与度を高めることによって、高い強度を備えた２次元炭素／炭素複合材料製のネジ部品を提供すると共に、ネジ部品が使用される雰囲気温度の大きな変化によって、炭素／炭素複合材料製のネジ部品に生じる熱応力を緩和して破損を防ぎ、ネジの締結部に生じる緩みを緩和することができる２次元炭素／炭素複合材料製のネジ部品を提供することを課題とする。【解決手段】短繊維炭素繊維を使用した異方性不織布を積層して製造された２次元炭素／炭素複合材料製のネジ部品において、ネジ部品の中心軸方向が、異方性を有する２次元炭素／炭素複合材料のＹ方向（短繊維炭素繊維が少なく配向された方向）に一致するように配向した構成のネジ部品とした。【選択図】図３
