“…The KS value obtained experimentally for CF-PLA composite at optimised condition was lower in comparison to PLA composite. KS value of PLA composite was reduced due to higher load bearing capacity along with increased strength and stiffness by reinforcement of carbon fibers, the obtained results are in line with the previous literature works [12][13][14][15][16][17][18][19][20][21][22][23].…”

Thermoplastic composites are acquiring more importance in various tribological applications due to their self-lubricity, low melting, and ease of fabrication. In this research article, processing via fused deposition modelling and dry sliding wear behaviour of neat and short carbon fiber reinforced polylactic acid composites have been investigated. A series of wear tests using a pin-on-disc wear apparatus was carried out by varying tribo-parameters namely applied load (10, 20, and 30 N), sliding velocity (0.5, 1.0, and 1.5 m/s), and sliding distance (1000, 2000, and 3000 m) following the response surface methodology. Analysis of variance was performed for optimizing the operating parameters with respect to minimum specific wear rate. The experimental outcomes showed decrease in specific wear rate of polylactic acid composites by 70 % in comparison to neat polylactic acid, due to reinforcement of short carbon fibers. Worn surface morphology of neat polylactic acid and carbon fiber reinforced polylactic acid show fine groves in the sliding direction, thinning of fibers and net work of microcracks and few pull-out of fibres from the matrix material.

“…Pramendra et al, [17] showed that specific wear rate and CoF of PLA composites can be reduced significantly by using natural fibers as reinforcements. Response surface methodology (RSM) serves as a good statistical tool for analysis and optimization of responses efficiently with minimum number of trials [18].…”

Fabrication of Aluminum LM13/MoS2/TiO2 hybrid metal matrix composite via stir casting technique was carried out to analyze the wear characteristics at an elevated temperature of 150° C using pin on disc tribometer. The parameters namely load, sliding velocity and sliding distance were varied for five levels as per the run order generated from Response Surface Methodology. From experiments, it was observed that the wear rate decreased with reduced sliding velocity initially due to mechanically mixed layer formation and then increasess. Also the results showed a reduction in wear rate with low loading and sliding distance conditions. Minimum wear rate was observed at a load of (11N), sliding velocity (1m/s) and sliding distance (848m) which was the ideal condition. Results concluded that the load applied was the significant factor over rate of wear leading to the occurrence of deep grooves along with delamination at higher loads. At minimal loads, appearance of shallow grooves in the sliding direction was observed.Major Applications of AMMC include the manufacturing of piston liners in automobiles and bearings, gears for aircraft engines which are often subjected to high friction and temperatures.

This work reports on the mechanical and wear performance of epoxy composite reinforced with short betel nut fiber (SBF). Composite samples with different weight percentages (0, 2, 3, 4, 6, and 8 wt%) of fiber content are fabricated through hand lay-up route. Mechanical properties such as tensile and flexural strengths are evaluated by conducting tests as per appropriate ASTM standards. Sliding wear tests are performed on a pin-on-disc test apparatus as per ASTM G99 standard. A non-linear regression model is developed in accordance with face-centered central composite design (FCCCD) of Response Surface Methodology (RSM). An artificial neural network (ANN) approach is applied to predict the wear rate of the composite and compared with the RSM predicted results. It is found that with the incorporation of short betel nut fiber both tensile and flexural strength of the composite shows an increasing trend. It is also observed that reinforcement of short betel nut fiber enhances the wear performance of epoxy. Surface morphologies of the worn samples have been studied to analyze the wear mechanism of the composite samples.
