An artificial hip joint consisting of multi-layer shell core composite structural components includes an artificial acetabular bone (1) and an artificial femoral head (2) which are mutually matched with each other. The artificial acetabular bone (1) has a multi-layer shell core composite structure and is constituted of a ceramic acetabular bone lining (1-1), transitional layers (1-2, 1-3), an acetabular bone shell made of a porous metal or a porous alloy or a porous toughened ceramic (1-4). The artificial femoral head (2) has a multi-layer shell core composite structure and is constituted of a ceramic spherical shell layer (2-1), a transitional layer (2-5) and a toughened ceramic inner core (2-2).The artificial acetabular bone lining and the artificial femoral head spherical shell layer of the hip joint have high rigid, anti-corrosion and anti-wear performance. The artificial acetabular bone shell layer and the femoral head inner core layer have high tough, shockresistant performance. The transitional layer adopts gradient composite material whose composition is between the shell layer and the inner core layer material, which has functions such as increasing bonding strength between the shell layer and the inner core layer and reducing interface stress between the shell layer and the inner core layer.La présente invention concerne une articulation artificielle de la hanche constituée de composants structuraux composites noyau-enveloppe multicouches qui comprend un os acétabulaire artificiel (1) et une tête fémorale artificielle (2) qui sont mutuellement adaptés l'un à l'autre. L'os acétabulaire artificiel (1) a une structure composite noyau-enveloppe multicouche et est constitué d'un revêtement d'os acétabulaire en céramique (1-1), de couches de transition (1-2, 1-3), une enveloppe d'os acétabulaire constituée d'un métal poreux ou d'un alliage poreux ou une céramique durcie poreuse (1-4). La tête fémorale artificielle (2) a une structure composite noyau-enveloppe mu
