Abstract: A belt for suspending and/or driving an elevator car extending longitudinally along a length of the belt. An inner belt layer formed from a first material is bonded to the plurality of tension elements at a first side of the belt. The inner belt layer forms an inner belt surface interactive with a traction sheave of an elevator system. An outer belt layer formed from a second material is bonded to the plurality of tension elements at a second side of the belt. The plurality of tension elements are located between the first side and the second side.

Abstract: A belt for suspending and/or driving an elevator car includes a tension member extending along a length of the belt, the tension member including a plurality of fibers bonded in a first polymer matrix, the plurality of fibers extending parallel to and discontinuous along a length of the belt and arranged with one or more lengthwise extending gaps between lengthwise adjacent fibers. A jacket substantially retains the tension member. A method of forming a tension member for an elevator system belt includes arranging a plurality of fibers into a fiber bundle. The plurality of fibers extend parallel to a length of the belt and have one or more lengthwise extending gaps between lengthwise extending fibers. The plurality of fibers is bonded to a first polymer matrix.

Abstract: A belt for an elevator system and a method for making the same is provided. The belt includes a plurality of tension members that extend along a length of the belt and a jacket. The jacket substantially retains the plurality of tension members. The jacket maintains a desired spacing and alignment of the tension members relative to each other. The jacket includes a plurality of first fibers and a plurality of second fibers. The jacket defines at least one exterior, traction surface of the belt. The first fibers are at least partially disposed between the tension members and the traction surface of the belt. The second fibers are fill fibers. The first fibers have at least one property that distinguishes them from the second fibers.
