Provided are: a cable bead which can realize a weight reduction while maintaining the breaking pressure resistance; and an airplane tire including the same. A cable bead (10) includes: a core (1) composed of an annularly formed steel; and a sheath (3) composed of at least one sheath layer, which is formed by spirally winding a sheath filament (2) composed of a steel around the core (1). The sheath filament (2) has a carbon content of higher than 0.90% by mass but 0.95% by mass or less, and a chromium content of 0.15 to 0.30% by mass.

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.
