Abstract: An article may include a carcass or jacket, and at least one composite member arranged within the carcass or jacket for inhibiting longitudinal stretch of the article. The composite member may include a plurality of fibers arranged in a polymeric binder, the polymeric binder bonding the composite member to the carcass or jacket. The carcass or jacket may be formed substantially of rubber or thermoplastic elastomer. The plurality of fibers may include fibers formed substantially from at least one of S-glass, aramid and carbon fiber. The polymer binder may be formed substantially of a thermoplastic material or of a thermoset material. In manufacturing of the article, the carcass or jacket may be extruded to surround the composite member. The article may be a handrail or an elevator belt.

Abstract: In a handrail including a carcass, a stretch inhibitor within the carcass, and a sliding layer bonded to the carcass, at least a portion of the carcass has a gas phase dispersed in a solid polymer matrix. The gas phase can reduce a density of the carcass by at least 5% or 10%, or about 15%, as compared to a density of the polymer matrix. The carcass can have a generally uniform distribution of gas bubbles in the polymer matrix, which can define a generally closed cell structure in the polymer matrix. The gas phase can be formed of particles of a syntactic foam dispersed in the polymer matrix. The handrail can further include a cover. The carcass and the cover can be formed of thermoplastic materials, and the cover can represent between 10 and 30% of the overall TPU required for the handrail.
