<p>A power transmission belt 50 having an inside surface and an outside surface. The power transmission belt has: a compression section 56 defining a plurality of laterally spaced, longitudinally extending ribs 58,60,62 made at least partially of rubber; a plurality of discrete, laterally extending reinforcing fibers in the ribs; a tension section 72 outside of the compression section and defined at least partially by a rubber layer; and a plurality of discrete, laterally extending reinforcing fibers 76 in the rubber layer of the tension section 72. The length of the reinforcing fibers 76 in the rubber layer of the tension section 72 is greater than the length of the reinforcing fibers 78 in the ribs (58,60,62). <IMAGE></p> |
