Enhancing Tribological Effectiveness of Polypropylene with Carbon
Fiber Composites via Fused deposition modeling Technology by Varying Infill
Speeds 2023-01-5127
Additive manufacturing (AM) is a common way to make things faster in
manufacturing era today. A mix of polypropylene (PP) and carbon fiber (CF)
blended filament is strong and bonded well. Fused deposition modeling (FDM) is a
common way to make things. For this research, made the test samples using a mix
of PP and CF filament through FDM printer by varying infill speed of 40 meters
per sec 50 meters per sec and 60 meters per sec in sequence. The tested these
samples on a tribometer testing machine that slides them against a surface with
different forces (from 5 to 20 N) and speeds (from 1 to 4 meters per sec). The
findings of the study revealed a consistent linear increase in both wear rate
and coefficient of friction across every sample analyzed. Nevertheless,
noteworthy variations emerged when evaluating the samples subjected to the 40m/s
infill speed test. Specifically, these particular samples exhibited notably
lower wear rates and coefficients of friction compared to the remaining test
samples in various dry sliding test conditions, encompassing applied load and
sliding velocity. This outcome strongly indicates that the utilization of a
40m/s infill speed in the fabrication of PP with CF composites yields enhanced
tribological performance. This enhancement can be attributed to the proficient
bonding of uniformly distributed particles and the efficient adhesion between
successive layers throughout the entire sample structure. Visual scrutiny of
scanning electron microscope (SEM) images depicting the worn surfaces further
elucidated the underlying wear mechanism. Particularly striking was the
observation that samples subjected to the 40m/s infill speed exhibited
diminished accumulation of debris and reduced plastic flow in comparison to
their counterparts. Findings strongly activist the use of this composite in
automotive and aerospace components requiring rotational or oscillatory
motion.
