Enhancing the Tribological Properties PETG and CFPETG Composites Fabricated by FDM via Various Infill Density and Annealing 2020-28-0429
One of the prominent representatives of tribo and thermal resistant for a class of polyester with high-strength, but still lightweight. The PETG with carbon fiber nano particle (PETGCF) composites also gives even more resistance of wear, heat and chemical, creating it an exceptional choice of application in automotive and other industries. This paper aims to study the influencing process parameter of FDM technique for different infill density (25%,50%,75%,100%) at various load condition and sliding distance on wear and friction characteristics of PETGCF under as- print and annealed condition was investigated via dry sliding tribo-meter apparatus. The trials were done by applying the load of 10N,20N,30N,40N, with a sliding distance of 1000m,2000m for the time period of 10 min at room temperature and responses such as wear rate and coefficient of friction were recorded for further analysis. The results show that the wear rate and coefficient of friction properties of PETGCF specimen change in improving way with a higher percentage for infill density of 75% and annealed condition of printed parts at all test parametric conditions. In which load and sliding distance increases wear rate increases for all the samples and followed by the coefficient of friction. The annealed PETGCF specimen with the infill density of 75% shows that the best wear and friction properties due to better strength and bonding at higher load and sliding condition. The annealed and infill percentage to afford a base work for any parts in conjunction with each other to improve wear and friction behavior. There will be numerous openings occurring for future research and the progression of three-dimensional printing in the tribological field.
