| Abstract: |
| Aramid short fiber/nitrile butadiene rubber（NBR） composites were prepared by wet mixing，and the effect of amount of thickening agent and aramid short fiber on the properties of the composites were studied．The results showed that addition of thickening agent including sodium polyacrylate（PNaAA） and polyethylene oxide（PEO） could improve the dispersion of aramid short fiber．The tensile properties of the composite with mass fraction of 0．007 5 PNaAA were the best．As aramid short fiber amount increased，the tensile properties of the composites increased firstly and then decreased．When the amount of aramid short fiber was 2 phr，the tensile properties of the composite were the best and the reinforcement effect of aramid short fiber was the best． |
