    • 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.
    • 具有弹性体的带,嵌入其中的抗拉绳,以及具有如本文所定义的织物拉伸韧度增加的牙织物。 织物拉伸韧性可以由构成织物的纱线的性质得出,例如纱线线密度,纱线极限伸长率,纱线拉伸强度,纱线填充密度和编织比。 织物拉伸韧性可以大于60mJ / mm2。 带可以是具有碳纤维拉伸绳的铸塑聚氨酯的齿形带。 还公开了一种改进用于齿形动力传动带的已知齿盖织物的方法,其涉及选择具有比已知织物更高的织物拉伸韧度的不同织物并且定向不同的织物,使得最高织物拉伸韧性的方向定向于 皮带的纵向。
