| description | A fixed-angle centrifuge rotor (10, 30, 61, 90) fabricated from fiber-reinforced composite material is disclosed that includes means for reinforcing radially outer portions (23, 78) of the cell holes (18, 58, 66, 76) in a direction transverse to the laminated layers (13, 70) of the rotor core (12, 32, 64, 92). In one embodiment, the reinforcement means is a material wound over the periphery of the rotor core (32, 92). In another embodiment, the reinforcement means is a material bonded into each of the cell holes (66). In a third embodiment, the reinforcement means is a formed region (74) of the laminated layers (70) to orient the fibers therein obliquely to the rotor axis (14).
On décrit un rotor centrifuge à angle fixe (10, 30, 61, 90) fabriqué à partir d'un matériau composite renforcé par des fibres qui comprend un moyen destiné à renforcer les parties externes radiales (23, 78) des orifices des alvéoles (18, 58, 66, 76) dans une direction transversale aux couches stratifiées (13, 70) du noyau du rotor (12, 32, 64, 92). Selon un mode de réalisation, le moyen de renfort est constitué par un matériau enroulé autour du noyau du rotor (32, 92). Selon un autre mode de réalisation, le moyen de renfort est constitué par un matériau collé dans chacun des orifices des alvéoles (60). Selon un troisième mode de réalisation, le moyen de renfort est constitué par une zone (74) des couches stratifiées (70) mise en forme, destinée à donner aux fibres une orientation oblique par rapport à l'axe du rotor (14). |
