Polymer composites are used extensively in the automotive, aviation, and sports sectors. Recently, researchers have replaced glass fiber with recyclable natural fibers. The present investigation examined the sliding wear performance of glass/sisal fibre (GF/SF)-reinforced hybrid polymer nanocomposite under various axial loads (AL) and sliding velocity (SV), with and without nSiC fillers.
A novel GF/SF fiber-reinforced hybrid nanocomposite with and without nano-SiC that complied with ASTM specifications was developed using a vacuum infusion technique. The percentage of nSiC fillers varied among 1 wt.%, 2 wt.%, and 3 wt.%. The pin-on-disc tribometer was employed to assess the tribological performance, viz., coefficient of friction (CoF) and wear rate (WR), of the composites at various process conditions.
The hybrid nanocomposite with 2 wt. % nSiC had the lowest CoF and WR of all the constructed composites. At 30N AL and an SV of 0.419 m/s, the GF/SF/2% nano-SiC composite exhibited wear resistance approximately 2.3 times more than that of the GF/SF composite without nanofibers, 1.5 times higher than that of the GF/SF/1% nSiC composite, and 1.46 times higher than that of the GF/SF/3%nSiC composite. The CoF for unreinforced and 2 wt.% nSiC reinforced composites under an AL of 30 N was 0.481 and 0.394, respectively.
The better wear properties of the GF/SF/2%nSiC composite were found to be due to uniform dispersion of nanofillers and stronger bonding between the fibres and the matrix.
The findings indicated the nSiC filler loadings to significantly improve the GF/SF fibre composite's wear properties.
