The influence of carbon black on the deformation-strength properties of high density polyethylene is considered. It was found that the deformation-strength properties of the polymer matrix change over the entire range of the filler content. The amount of carbon black that can be introduced into high-density polyethylene and obtained a composite material with the optimal combination of stiffness, strength and ductility is established. It was shown that the change in the deformation-strength properties of composites is due to the behavior and influence of carbon black particles on the structure of the polymer matrix.

AbstractWe have studied friction, scratch resistance and electrical resistivity in high density polyethylene (HDPE) + carbon black (CB) composites in relation to electric resistivity percolation threshold. Below the threshold, CB addition lowers dynamic friction by providing a smaller surface area of contact of the composites with the pin surface; the effect is stronger at higher loads. Above the percolation concentration, an increase in friction is seen due to formation of CB agglomerates and thus an increase in the area of contact. The recovery depth in scratch testing behaves similarly as dynamic friction and for the same reasons, particularly so at high loads, with a minimum at the percolation threshold. Thus, at the threshold we have simultaneously superior scratch resistance, low dynamic friction and low electric resistivity.

In this study, surface roughness and burr were investigated in drilling of pure and carbon black reinforced high-density polyethylene at three cutting speeds and feeds with three drill point angles. The measurement results of surface roughness of drilled holes were evaluated by Taguchi and analysis of variance statistical methods to specify the optimal drilling parameters and the effects of selected drilling parameters. According to the results, lower surface roughness and fewer burrs were obtained in drilling at high cutting speed and low feed with drill tools having small point angle and it was specified that the carbon black reinforcement reduced the surface roughness. Additionally, the optimal drilling parameters were determined as drill point angle of 80°, feed of 0.1 mm/rev and cutting speed of 120 m/min and the most effective parameter was found as drill point angle and the least effective parameter was found as feed.
