Mechanical and Tribological Behavior of Unsaturated Polyester Nan carbon Black Composite


Experimental work had been done to demonstrate the effect of nanocarbon black particles (N220) contents on the mechanical and tribological behavior of unsaturated polyester nanocomposite prepared via ultrasonic wave dispersion method. The results showed that the mechanical and tribological behavior was enhanced when the nanocarbon black particles content was increased up to 2%wt. and then decreased after that. The improvements in compressive strength and flexural strength are (16.13% at 2%wt. and 25.2% at 1%wt.), respectively, While The improvements in the hardness and wear resistance are (14.65% and 25.76% ) at 2%wt. , respectively.
