Abstract:
      The effects of different types of short fiber(length) on the properties of ethylene-propylene-diene rubber(EPDM) composites were investigated.The results showed that,the composite using aramid short fiber (refered to as AF)(9 mm)/basalt short fiber (refered to as BSF)(9 mm) with a blending ratio of 1/1 had a smaller Mooney viscosity,the lowest DIN wear(113.51 mm3),and the best ablation resistance.The basic properties and thermal stability of the composite with precipitated silica were comparable to those of the composite with gas-phase silica.The greater the length of BSF was,the better the wear resistance and ablation resistance of the composite were.As the length of BSF increased,the Payne effect of the composite decreased.Compared with the BSF(3 mm) composite,the BSF(9 mm) composite had the smallest Payne effect,and the dispersibility of BSF(9 mm) was best .In TG analysis,at 700 ℃,the quality retention rate of the composite in descending order was the BSF(9 mm)/AF(9 mm) blend composite,BSF(3 mm) composite,AF(9 mm) composite,AF(6 mm) composite,AF(3 mm) composite.
