Abstract: A belt having an elastomeric body, a tensile cord embedded therein, and a tooth fabric having an increased value of Fabric Tensile Toughness as defined herein. The Fabric Tensile Toughness may be derived from properties of the yarns making up the fabric, such as yarn linear density, yarn ultimate elongation, yarn tensile strength, yarn packing density and weave ratio. The Fabric Tensile Toughness may be greater than 60 mJ/mm2. The belt may be a toothed belt of cast polyurethane with carbon fiber tensile cord. Also disclosed is a method of improving a known tooth cover fabric for a toothed power transmission belt involving selecting a different fabric having a higher Fabric Tensile Toughness than the known fabric and orienting the different fabric so the direction of highest Fabric Tensile Toughness is oriented in the longitudinal direction of the belt.

Abstract: A belt having a tensile cord (12) embedded in the belt, extending in a longitudinal direction and made up of two components: a tensile component (31) and a sacrificed component (32'). The sacrificed component may be broken into a plurality of discontinuous segments (32'). The tensile component provides most of the reinforcement of the belt. The sacrificial component of the precursor cord protects the tensile component from excessive stretching during cord treating and winding, but breaks, melts, or yields during mandrel expansion during the belt molding process, thus preserving the stretchability of the tensile component.

Abstract: A V-ribbed belt that includes a ribbed surface covered with fabric is provided. The fabric is stretchable in two predetermined directions. A method for manufacturing the V- ribbed belt is also provided. The method includes placing a belt matrix about a mandrel, placing a fabric about the external circumference of the belt matrix which wraps around the mandrel, placing the mandrel inside a shell having a plurality of grooves on the internal circumference, expanding the belt matrix and the fabric toward the internal circumference of the shell and thus pressing the fabric onto the internal circumference having the multi-ribbed structure, and curing the belt matrix with the fabric. The fabric is stretchable to accommodate itself to the multi-ribbed structure.
