Properties Of Composites

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.

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.

The present study investigates the effect of the carboxylated multi-walled carbon nanotube (0~3 wt %) content on the electrical and thermal properties of high density polyethylene/carbon black/carboxylated multi-walled carbon nanotube (HDPE/CB/c-MWNT) hybrid nanocomposites. The room temperature electrical resistivity and positive temperature coefficient (PTC) intensity of the nanocomposites significantly improved with the addition of c-MWNT. However, the heat of fusion decreases as the amount of c-MWNT increases. Further, the microstructural parameters such as the fractional free volume (Fv) and free volume hole size (Vf) of the nanocomposites shows appreciable changes around the percolation threshold. Secondly, the PALS results seem to correlate well with the electrical and thermal properties of the composites.
