Claims7
A synchronous power transmission belt comprising a belt body of cast urethane belt material;
- belt teeth formed of the body and spaced apart at a pitch;
- a wear-resistant fabric reinforcement disposed along peripheral surfaces of the belt teeth;
- a tensile member of helically spiraled cord having length and volume embedded in the belt body and of a yam of fibers;
- and wherein the improvement comprises:
- a tensile member of a cord of a yarn of carbon fibers with interstices between the fibers;
- and
- belt material penetrating at least a portion of the cord interstices as the belt is cast wherein the cord interstices contains a minimum of about 0.21 mg of belt material per mm.sup.3 of cord volume for each mm of cord length.
