【Abstract】 The mechanical properties and stress relaxation behavior of the nylon 6 short fiber-NR/ SBR composite in which the short fiber was treated with RFL solution were investigated. By means oi the RES and SEM, the bonding strength between the fiber and matrix and the morphology of the composite were also determined. The results showed that the treated fiber could remarkably improve the mechanical properties and give the composite marked anisotropy of mechanical properties, because the treatment of short fiber not only increased the bonding strength between the fiber and matrix but also significantly improved the dispersibility and orientability.The incorporation of the short liber resulted in two different rate stress relaxation processes, and the time at which the earlier relaxation process is exhausted depended on the short liber content.更多还原
