| Abstract: |
| The development of steel wire braided rubber hose with service life over 300 000 impulse cycles was described.The rubber hose was composed of inner layer， reinforced layers （2 steel wire braided layers），middle layer，and outer layer.The matrix materials of inner and middle layers were NBR with high and medium acrylonitrile contents，respectively.The matrix material of outer layer was rubber-plastic alloy.The properties of inner，middle and outer layers met the requirement specified in the enterprise standard，and the properties of rubber hose met the requirement of SAE J 517 R17 standard.The service life of the rubber hose reached 300 000 impulse cycles that far exceeded the standard requirement. |
