    • A power transmission belt having a body with a rubber layer defining spaced friction drive surfaces at laterally oppositely facing side surfaces. Short reinforcing fibers are embedded in the rubber layer in an amount of 15-50 parts by weight per 100 weight percent of rubber in the rubber layer. The short reinforcing fibers include polyamide short reinforcing fibers that make up at least 50 weight percent of the short reinforcing fibers embedded in the rubber layer. A plurality of the polyamide short reinforcing fibers project from the friction drive surfaces and have exposed, flattened ends. Flat particles of inorganic powder are adhered to the friction drive surfaces to reside captively between the flattened ends of the polyamide short reinforcing fibers and locations on the friction drive surfaces at which the short reinforcing fibers do not project.
    • 一种动力传动带,其具有主体,该主体具有在横向相对的侧表面上限定间隔开的摩擦驱动表面的橡胶层。 短的增强纤维以橡胶层中每100重量%橡胶的15-50重量份的量嵌入橡胶层中。 短增强纤维包括构成嵌入橡胶层中的短增强纤维的至少50重量%的聚酰胺短增强纤维。 多个聚酰胺短增强纤维从摩擦驱动表面突出并具有暴露的扁平端。 无机粉末的平坦颗粒粘附到摩擦驱动表面上,以紧靠的方式驻留在聚酰胺短增强纤维的扁平端和摩擦驱动表面上的短增强纤维不突出的位置。
