“…The delamination factor at the exit of the hole creates various research opportunities for engineers, scientists and researchers; therefore, it is very di cult to compare the research work of this investigation with the literature because many experimental studies showed that the delamination factor gets affected by the composite manufacturing process (Rezghi et al 2019), tool type and geometry ) and selection of machining parameters (Malik et al 2021). For comparison, the delamination factor during the drilling of jute/polypropylene was found to be varied from 1.23-2.09 (Pailoor et al 2021), while for the current investigation delamination factor was varied from 1.096-1.301. The output response as a delamination factor of our experimental study was higher than the delamination factor of drilling of the ax/polylactic acid (Lot et al 2018).…”

This paper discusses on fabrication, testing and evaluation of delamination factor of nettle fiber based composites for low duty applications. The randomly oriented nettle fibers were used to fabricate the biocomposite by conventional hand lap up technique. Epoxy and Nettle based composite plates were developed by varying fiber weight percentage from 5% to 25%. The flexural, tensile, impact, chemical resistance and water absorption rate of developed nettle fiber based biocomposite were examined for different fiber weight fractions in the randomly oriented patterns as a unique and innovative attempt. During the investigation, flexural strength and tensile strength were improved up to 20 wt% of fiber addition and then it was decreased. This resulted in a continuous rise in impact strength with an enhancement in fiber wt. %. The influence of fiber weight percentage on water absorption and chemical resistance of fabricated composite was examined in different environments. The result showed that the nettle fibers can be used as an essential reinforcing material to design and fabricate mechanical and structural members for low duty application. The chemical behavior of nettle based composite was studied by the FTIR spectroscopy method and the presence of chemical functional group was confirmed. The drilling behavior of developed nettle/SiC/epoxy hybrid composites was evaluated by consider cutting process parameters like feed rate (0.125, 0.212 and 0.3 mm/rev), spindle speed (400, 600, 800 rev/min) and drill diameter (4, 6, 8 mm). Analysis of variance was used in designing experiments for the current investigation. Feed rate was found to be a very impressive factor in influencing the delamination factor.

“…Machining at high speed increases the drill tool temperature, this produces a thermal softening effect on the tool material which in turn increases the chip formation and reduces the thrust force. 70 Pailoor et al 90 analysed the jute fibre composite chip formation during drilling and witnessed continuous ribbon type chips at an increased feed rate. Owing to high deformation at minimum spindle speed and maximum feed rate, the chips formed were thicker and are curly.…”

Natural fibre composites are the promising replacement for synthetic fibre owing to their improved properties, and more importantly, natural fibres are biodegradable and of low cost. These characteristics have made them viable for contemporary engineering and structural applications. However, large scale production of natural fibre composites is in prone because of the challenges in manufacturing and machining. Fibre composite exhibits poor machinability characteristics owing to their heterogeneous and anisotropic behaviour. To overcome this problem, various steps and new methodologies have been established in the view to produce quality machining in natural fibre composites. In recent years, the possibility of conventional machining in natural fibre composites was also discussed. In the present review study, an effort has been taken in studying the fibre composite’s machining characteristics and their failure mechanism in both conventional and unconventional machining. The influence of process parameters in machining different natural fibre composites is also discussed.

“…The investigation concluded that fly ash particles contributed to enhanced machinability. Pailoor et al 32 investigated the drilling on jute fiber-reinforced polypropylene composites manufactured using in-line compression molding. Fiber direction (longitudinal & transverse), coupling agent (with & without), fiber content (20, 30 & 40 wt %), fiber type (chopped & continuous), spindle speed (600, 1260 & 270 r/min), feed rate (0.1, 0.2 & 0.3 mm/rev), drill diameter (2, 3 & 4 mm), and drill material (HSS & Co-HSS) were the different influencing parameters and levels used in this study.…”

“…Sandhyarani et al 27 examined the influence of coupling agent, fiber type and direction, spindle speed, feed rate, drill material and diameter on compression moulded jute fiber reinforced polypropylene composites. The results revealed that minimum thrust force and delamination was observed in the specimens without coupling agent and transversely oriented 40% fiber content with the drilling parameters of low feed rate, high spindle speed and 4 mm Co-HSS drill.…”

Natural fiber reinforced composites are becoming popular in various industrial and commercial applications as structural components. Unlike conventional materials, machining of fiber composites is critical due to its heterogeneous structure. Hence, it is necessary to understand the machining behaviour of fiber reinforced composites. Hybrid composites reinforced with banana fiber and fly ash filler in polyester matrix were fabricated and then evaluated for drilling performance. Drilling experiments were performed using the Taguchi L27 orthogonal array. The influence of feed rate (A), cutting speed (B) and filler content (C) on thrust force, surface roughness, and delamination factor entry and exit were using Taguchi and Analysis of variance (ANOVA) techniques. The results revealed that (i) Minimum thrust for attained at filler content (A) 1 vol %, speed (B) 3000 r/min, and feed (C) 100 mm/min, (ii) Minimum surface roughness at filler content A (3 vol %), speed B (2000 r/min), and feed rate C (100 mm/min) and (iii) Minimum peel up and push out delamination at filler content (A) as, 5vol %, speed (B) 2000 r/min, and feed (C) 100 mm/min. This study provides machining insights on agro-industrial waste based polymer composites for structural applications.
