Abstract: A belt for an elevator system includes a tension member extending at least partially across a belt width and extending longitudinally along a length of the belt, the tension member formed at least partially from a plurality of aromatic polyester based fibers, and a jacket material at least partially encapsulating the tension member. An elevator system includes a hoistway, an elevator car located in the hoistway and movable therein, and a belt operably connected to the elevator car to suspend and/or drive the elevator car along the hoistway. The belt includes a tension member extending at least partially across a belt width and extending longitudinally along a length of the belt. The tension member is formed at least partially from a plurality of aromatic polyester based fibers. A jacket material at least partially encapsulates the tension member.

Abstract: A belt for an elevator system includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt and a jacket at least partially enclosing the plurality of tension members. The jacket defining a traction side of the belt configured to interface with a traction sheave of an elevator system. The jacket includes a base material layer, and a coating layer positioned over the base material layer formed from a self-extinguishing fluoroelastomer material. A method of forming a belt for an elevator system includes forming a plurality of tension members and encapsulating the plurality of tension members in a jacket. The jacket includes a base material layer and a coating layer formed from the self-extinguishing fluoroelastomer material.
