Unveiling the frictional properties of brake pads developed from silver nanoparticles modified carbon nanotubes derived from rice husks

Abstract

The development of brake pads using eco-friendly materials was spurred by the health risks associated with the use of brake pads based on asbestos. In this experiment, the frictional substance used to develop vehicle brake pads, which was based on asbestos, was replaced with carbon nanotubes made from rice husk. The impacts of the wear parameter were evaluated experimentally using Taguchi-Grey's (GRA) multi-response analysis. The wear rate, wear depth, and coefficients of friction were the three multi-response variables that were selected. The modified sol-gel and solution-stir-cast technique was used to develop the brake pads. The results show an ideal point of 1.5 wt% carbon nanotube made from rice husk, a 20 N applied load, a 3 m/s sliding speed, a 25 m sliding distance with 2.15 mg/m, a wear depth of 5 mm, and a COF of 0.42. At a 95% confidence level, the predicted and experimental GRA were fairly similar. The designed brake pad system's achieved frictional qualities meet industry requirements. It is known that silver nanoparticle modified carbon nanotubes made from rice husk biomass may be utilised to make high-friction brake pads using the advanced method.
