Abstract:
(EN) The purpose of the present invention is to further improve the strength and durability of a wire rope. A wire rope 10 according to the present invention is provided with: a core rope 11 that is formed from a steel; a cover layer 12 that covers the outer circumference of the core rope 11 and is formed from a composite resin; and a plurality of lateral strands 13 that are formed from a steel and are wound around the outer circumference of the core rope 11, which has been covered by the cover layer 12. The composite resin that constitutes the cover layer 12 is obtained by blending cellulose nanofibers into a polypropylene resin that serves as the matrix.
(FR) La présente invention vise à améliorer davantage la résistance et la durabilité d'un câble métallique. Un câble métallique (10) selon la présente invention comprend : un câble central (11) qui est constitué d'un acier ; une couche de couverture (12) qui recouvre la circonférence extérieure du câble central (11) et qui est constituée d'une résine composite ; et une pluralité de brins latéraux (13) qui sont constitués d'un acier et qui sont enroulés autour de la circonférence externe du câble central (11), qui a été recouvert par la couche de couverture (12). La résine composite qui constitue la couche de couverture (12) est obtenue par mélange de nanofibres de cellulose dans une résine de polypropylène qui sert de matrice.
(JA) この発明は,ワイヤロープの強度および耐久性のさらなる向上を図ることを目的とする。ワイヤロープ10は,鋼製の心ロープ11と,心ロープ11の外周面に被覆された複合樹脂製の被覆層12と,上記被覆層12が被覆された心ロープ11の外周面に巻き付けられた複数本の鋼製の側ストランド13とを備えている。被覆層12を構成する複合樹脂は,母材であるポリプロピレン樹脂にセルロースナノファイバを配合したものである。
