摘要：

Carbon nanotubes (CNTs) and carbon black (CB) were used as the hybrid reinforcing fillers, the coordinated effect of different fillers on the properties of composites was investigated. The filling content of CNTs increases as the decrease of CB content, and the mass ratio of CNTs increase to CB decrease is fixed to m (CNTs):m(decreasing amount of CB)=1:2.5.The dispersion of CNTs at the brittle fracture surface was gottenby the scanning electron microscopy (SEM). The flatness and height difference of the tensile fracture-surface were observed by 3D measuring laser microscope. The tensile strength was the best when 4 phr CNTs was filled, that was 11.41% higher than that of composites with 0 phr CNTs. The processability was worse and the modulus was enhanced, abrasion property increased with the increase of CNTs and composites with 8 phr CNTs was 21.14% more wearable than 0 phr CNTs. According to the loss factor of dynamic mechanical analysis (DMA), rolling resistance of composites was reductive but wet-skid resistance decreased with the increase of CNTs. © All right reserved.
