“…It has been proved that the addition of these nanophases also affects the rheological properties of the nanocomposites, increasing the elastic behavior with a reduction of the ductility. On the other hand, GnP have been used as additive in poly(carbonate) (PC) and PC-ABS blends [85,86], increasing the mechanical properties of the nanocomposite but without the loss of ductility and an improvement on the thermal stability. Reactive extrusion is utilized to prepare conductive nanocomposites composed by poly(butylenetherephtale) (PBT) with several graphenic materials [87].…”

This review is focused on the recent developments of nanocomposite materials that combine a thermoplastic matrix with different forms of graphene or graphene oxide nanofillers. In all cases, the manufacturing method of the composite materials has been melt-processing, in particular, twin-screw extrusion, which can then be followed by injection molding. The advantages of this processing route with respect to other alternative methods will be highlighted. The results point to an increasing interest in biodegradable matrices such as polylactic acid (PLA) and graphene oxide or reduced graphene oxide, rather than graphene. The reasons for this will also be discussed.

“…Dynamic storage modulus represents the elastic part which determines the ability of material to store energy when deformed under an external stimulation. 13,23 Figure 6(a) exhibits the storage modulus of the bare PLA, Cu particle(40 wt%)/PLA composites with-and without 20 wt% PMMA beads. The storage modulus of all samples decreased as increasing temperature.…”

“…9 FDM technology has been applied for the 3D printing of several amorphous thermoplastics, such as acrylonitrile-butadiene-styrene (ABS), 10 poly(lactic acid) (PLA), [9][10][11] and thermoplastic polyurethane (TPU). 12,13 Although 3D printing method offers remarkable advantages compared with conventional manufacturing approaches, several researches were reported that it often provides poor thermal and mechanical properties. [13][14][15] It could be due to the poor adhesion between adjacent printed layers and pores in final objects.…”

Poly(lactic acid) (PLA) composite filaments with different copper (Cu) contents as high as 40 and 20 wt% of poly(methyl methacrylate) (PMMA) beads have been fabricated by twin-screw extruder for 3D printing. A fuseddeposition modeling (FDM) 3D printing technology has been used to print the PLA composites containing hybrid fillers of Cu particles and PMMA beads. The morphology, mechanical, and thermal properties of the printed PLA composites were investigated. The tensile strength was slightly decreased, but storage modulus and thermal conductivity of PLA composites were significantly improved by adding Cu particles in the presence of PMMA beads. The PLA composites with hybrid fillers of 40 wt% of Cu particles and 20 wt% of PMMA beads resulted in thermal conductivity of 0.49 W m −1 K −1 which was three times higher than that of the bare PLA resin. The facilitation of the segregated network of high-thermally conductive Cu particles with the PMMA beads in PLA matrix provided thermally conductive pathways and resulted in a remarkable enhancement in thermal conductivity.

“…The three dimensional model data is fed into the system after slicing, which prints the material on the defined parameters like angle of orientation, layer thickness, width, raster angle and built direction. The nozzle makes its movement in x and y direction and the bed moves in z direction [11]. Pramaan prusa i3 technology printer was used for the development of parts available at Global 3D labs, Bangalore.…”

This paper focuses on the development of copper filled Acrylonitrile Butadiene Styrene (ABS) composites by fused deposition modelling (FDM) and to characterize its friction and wear behaviour. Twin screw extrusion technique was employed to extract copper-ABS composite filament. Three different materials were tested, i.e. pure ABS, ABS+2.5wt% Cu and ABS+5wt% Cu. Friction and wear characteristics of pure ABS and copper filled ABS composites were tested under various loads and sliding velocities. Addition of Copper powder has significantly improved the friction and wear properties of the developed composites. Further, it is also observed that friction and wear behaviour increased with increase in copper content in ABS. Worn out surfaces were subjected to scanning electron microscopy studies to analyse and identify the possible wear mechanisms involved.
