Abstract
An illustrative example embodiment of an elevator load bearing member includes a unidirectional weave of a plurality of load bearing fibers including at least a first material and a second material. A melting point of the first material is higher than a melting point of the second material. The plurality of load bearing fibers are bonded together by at least some of the second material that is at least partially melted. A coating covers the plurality of load bearing fibers.
Claims16
An elevator load bearing member, comprising:
- a unidirectional weave of a plurality of load bearing fibers including at least a first material and a second material, wherein at least some of the load bearing fibers comprise the first material and the second material, wherein a melting point of the first material is higher than a melting point of the second material, and wherein the plurality of load bearing fibers are bonded together by at least some of the second material that is at least partially melted;
- and
- a coating over the plurality of load bearing fibers.
An elevator load bearing member, comprising:
- a unidirectional woven sheet of a plurality of load bearing fibers including at least a first material and a second material, the first material having a melting point that is higher than a melting point of the second material, wherein the plurality of load bearing fibers are bonded together by at least some of the second material that is at least partially melted, wherein at least some of the load bearing fibers comprise the first material and the second material;
- and
- a coating over the plurality of load bearing fibers, the coating having a rectangular cross section defining a width of the elevator load bearing member, wherein the sheet of the plurality of load bearing members is continuous and extends across a majority of the width.
