| Abstract: |
| The properties of EPDM V-ribbed belts with aramid cords were investigated， and compared with those of EPDM V-ribbed belts with polyester cords. The results showed that the aramid cords reinforced EPDM V-ribbed belts possessed higher strength and modulus and lower elongation.The transmission power of the EPDM V-ribbed belts with aramid cords was stronger，thestressdecay was slower，and the fatigue life was extended. The aramid cords reinforced EPDM V-ribbed belts was an ideal belt to be used in front end of the auxiliary drive（FEAD） and beltdriven integrated startedgenerator（ B-ISG）for modern automobiles. |
