  • Chain link
    Patent number: 8161723
    Abstract: Chain link comprising two side limbs at both ends joint by curved end portions. The chain Link comprises at least one endless band of fiber material wound along the perimeter of the chain link. The fiber material follows the longitudinal direction of the limbs and the curvature of the end-portions. In a chain made of interlocking chain links of this type, all tensile loads are absorbed by the fiber material, whereas the bearing load due to interlink contact, plus the link shear and bonding stresses near the contact points are absorbed by the end portions.
