Mechanical and tribological behavior of particulate filled silicon nitride reinforced nylon-6 polymer composites

Abstract

From the Research, it found that there is an impact of Silicon Nitride (Si3N4) on the mechanical properties of Nylon 6 or polyamide 6 based composites. Nylon 6 prepared with Silicon Nitride (Si3N4) by changing the weight proportions. The hardness and wear properties of Nylon-6/Si3N4 composites have investigated. Experiments were carried out as per Taguchi's design. Rockwell, hardness testing device, used to observe the hardness number of different nylon-6/ Si3N4 composites and the pin-on-disc wear test (ASTM G99) conducted with different combinations of reinforcement, sliding distance, sliding speed and normal load. Scanning electron microscopy (SEM) was used to look at the break surfaces microstructure of wear and tensile tests. The increase of Si3N4 upgrades the existence state of typical Nylon 6 to a more important point.
