Aluminium (Al)/Aluminium alloy composites are emerging as very promising materials, especially in the fields of aerospace and automotive for their various attractive and technically demanding properties. Discontinuously reinforced aluminium metal matrix composites with reinforcements as nanoparticles of ceramics in general and carbon nanotubes in particular have emerged as the forerunner for a ...

Carbon nanotube (CNT)-reinforced silver and copper metal matrix composites—at three different reinforcement phase concentrations (0.5 wt.%, 0.75 1 wt.%)—were produced via powder metallurgy sintered hot uniaxial pressing. Optical electron microscopy techniques were used to characterize the mixtures composites. The latter also electrically characterized load-dependent electrical contact resistanc...
