Abstract:
Provided are a high-strength fiber composite and an applied product thereof, whereby it is possible for the inherent tensile strength of high-strength fiber yarns to be obtained, even when used in applications in which bending stress occurs, such as wires, or when stored while wound around a drum or the like. This high-strength fiver composite has a core produced by imparting twist to a high-strength fiver bundle produced by bundling high-strength fiber yarns, and a stiffening the twisted high-strength fiber bundle with a stiffening agent. In this high-strength fiber composite, the high-strength fiber yarns are resistant to breakage even when flexed, have a superior shearing strength, and can maintain the inherent tensile strength of high-strength fibers, even when used in applications in which bending stress occurs, such as wires, or when stored while wound onto a drum or the like. The strand structure, which has a strand construction composed of two or more of the high-strength fiber composites twisted together, maintains the inherent strength of the high-strength fibers, and affords more consistent tensile strength, as compared with when an equal number of high-strength fiber composites lacking the strand construction are used.
Abstract:

A ballistic resistant article comprising high strength Spectra fibers and expanded PTFE fibers, wherein the article is a fabric further comprising a V50 of greater than about 735 ft/s (224 m/s) at a fabric weight of about 0.75 lb/ft2 (3.7 kg/sq m) and a bending moment at room temperature of less than about 0.0007 N-m.
Abstract:
Helically stranded thermoplastic polymer composite cable (10) includes a single wire (2) defining a center longitudinal axis, a first multiplicity of thermoplastic polymer composite wire (4) helically stranded around the single wire (2), and a second multiplicity of polymer composite wire (6) helically stranded around the first multiplicity of thermoplastic polymer composite wire (4). The helically stranded thermoplastic polymer composite cable (10) may be used as intermediate articles that are later incorporated into final articles, such as electrical power transmission cables, including underwater tethers and underwater umbilicals. Methods of making and using the helically stranded thermoplastic polymer composite cables are also described.
Abstract:
The invention relates to an abrasion resistant fabric containing ultra high molecular weight polyethylene (UHMWPE) filaments and thermotropic liquid crystal polymers (LCP), the use thereof as protective means and to a protective cover containing said fabric. In particular, the invention relates to a rope and to a roundsling containing the protective cover.
Abstract:
A deformed metal composite wire (14) comprises a matrix (12) of a first metal having a first melting point. The composite wire also comprises two or more filaments (10) of a second or further metal embedded in the matrix (12) and surrounded by the matrix (12). The second or further metal has a melting point which is higher or equal to the first melting point. The wire (14) is in a deformed state so that the two or more filaments (10) have a non-circular filament cross-section.
