The present invention relates to a mooring rope for use in subsea mooring, or a substantially synthetic rope thereof, said synthetic rope comprising a rope core and a layered shell arranged around the rope core, said the shell having a braided outer shell layer. The shell comprises sub-surface buoyancy elements, suitable for use in a subsea environment, extending in radial direction between the rope core and the outer shell.

The disclosure provides a sling including a sleeve, a first eye formed by a first splice, and a second eye formed by a second splice. The sleeve includes braided strands and has a first end portion, a second end portion, and an intermediate portion between. The sleeve also defines a hollow inner volume. The first splice is made by the first end portion extending into and along part of the hollow inner volume proximate the first eye. The second splice is made by the second end portion extending into and along part of the hollow inner volume proximate the second eye. A hollow load bearing portion is defined in the intermediate portion between the first splice and the second splice.

The present invention addresses the problem of providing a twisted cord of liquid-crystal polyester multifilaments which gives various high-order processed products capable of retaining desired product shapes and which is suitable for use in general industrial material applications such as high-strength ropes, slings, and nets. The twisted cord of liquid-crystal polyester multifilaments has a coefficient of variation in longitudinal-direction cord diameter, X, of less than 30%.

A tension element of an elevator system tension member includes a plurality of first polymer fibers of a first material extending along a length of the tension element, and a plurality of second polymer fibers of a second material different from the first material. The plurality of second polymer fibers have a melting point lower than that of the plurality of first polymer fibers. The plurality of second polymer fibers are fused to the plurality of first polymer fibers to serve as a matrix for the plurality of first polymer fibers.

A braided structure that includes a core and a sheath is provided. The core includes a yarn formed at least in part from an aromatic polymer (e.g., an aromatic polyester/liquid crystalline polymer or an aramid polymer), and the sheath, which includes a plurality of ultra high molecular weight polyolefin yarns, is braided around the core. The sheath has an overall diameter ranging from about 60 micrometers to about 650 micrometers. Despite its small diameter, the braided structure can be creep resistant and abrasion resistant while at the same time exhibiting low elongation, a high load at break, and high stiffness. The braided structure can be used in medical applications such as sutures, load bearing orthopedic applications, artificial tendons/ligaments, fixation devices, actuation cables, components for tissue repair, etc.
