“…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.

“…These features reveal that the inclusion of fibre in the biocomposite increases the complexity of the wear mechanism. The smoothing of the fibre surface and the reduction of flake formation indicate that the applied stress from the antagonist is dominated by the fibres rather than the resin matrix 35 . Hence, the degree of resin matrix damage for Group L is lower compared to Group K. Nevertheless, the addition of fibre by 5 wt% does not reduce the specific wear rate of the overall biocomposite.…”

Fibre-reinforced biocomposites usage has gained prominence over the past decade. Although higher fracture toughness was observed when fibres were added to biocomposites, material degradation could occur due to filler and fibre content intolerance in the biocomposite matrix. Optimisation of resin-fibre-filler ratios helps in increasing the tribological performance of high load-bearing applications. However, the tribological performance is less understood due to limited in-vitro studies on the effect of fibre microstructures. A comprehensive investigation of the reciprocating and rotary wear behaviour of different compositions was carried out by varying fibre (0%, 5%, 10% and 15%) to particulate filler (40%, 45%, 50%, and 55%) weight fractions. The investigation aimed to identify the optimal composition of fibre-reinforced biocomposites based on the in-vitro ball-on-disc reciprocating and rotary wear tests in the presence of modified Fusayama solution. The cross-sectional areas of wear tracks were analysed using laser microscopy and scanning electron microscopy techniques to assess the surface morphology and subsurface damage of the wear tracks on biocomposites and the antagonist. The numerical results were statistically analysed using two-way ANOVA followed by a posthoc Tukey’s test (p = 0.05). The results showed a combination of adhesive, abrasive and fatigue wear for all the tested Groups. The friction coefficient had a longer transient period for the 5 wt% and 10 wt% Groups. Based on the surface roughness, coefficient of friction, SEMs, specific wear rate, and ease of manufacturing, the threshold limit for fibre loading was found to be 10 wt%. The rotary test had a considerably lower specific wear rate compared to the reciprocating test. Fibre weight fraction was found to be the influencing factor of the abrasive wear behaviour compared to fibre length for the tested Groups.

“…The carbon fiber‐reinforced PA has been analyzed for wear resistance behavior. A study has shown that wear rate strongly relates to the fiber alignment of CFRPs 141 . Similarly, carbon fiber‐reinforced PEEK manufactured through FDM has demonstrated wear resistance behavior, which shows the potential of additively manufactured CFRPs for wear‐resistant surfaces 142 .…”

Additive manufacturing has new revolutionary potential for carbon fiber‐reinforced polymers (CFRPs). Additive manufacturing of CFRPs combines the advantages of additive manufacturing such as customization, minimal wastage, low cost, fast prototyping and rapid manufacturing with high specific strength of carbon fiber. This article delivers a comprehensive review of additive manufacturing of short and continuous CFRPs. The article presents insight into different additive manufacturing techniques with an overview of commercially available methods for manufacturing short and continuous CFRPs. This review also includes mechanical characterization and analytical techniques discussed in the literature for CFRPs. The robust applications of short and continuous CFRPs in biomedical, electronics, and aerospace would highlight the importance of research and development in this field. In the end, drawbacks, recent innovations, and the future research directions underline the gap between research and commercialization of additive manufacturing of short and continuous CFRPs.
