“…Furthermore, it is also observed that the Fd value exceeds 1.8, 2.5 and 1.6 when d and N are between 7.9-9.2 mm and 1295-1400 rev/min for Fd1, 6-10 mm and 720-1400 rev/min for Fd2 and 9.8-10 mm and 1295-1400 rev/min for Fd3, respectively. These results are fully consistent with those observed by Belaadi et al [28,46] for epoxy/jute fabric biocomposites under identical cutting conditions. In the case where the drill diameter is kept constant, the Fd factor increases with increasing feed rate.…”

“…The drilling tests were performed using a MOMAC universal milling machine equipped with a 1400 rpm spindle with a feed rate of 4.6 to 1040 mm/rev [28,46], and all drilling was performed on this machine. During the drilling phase, to limit the bending of the parts to avoid amplifying the defects at the exit of the hole, a solid steel support was placed under the composite parts.…”

“…Recently, Belaadi et al [28] performed interesting research on the effect of drilling parameters such as the spindle speed, feed rate and drilling diameters on jute/polyester staple fiber biocomposites to estimate the influence of the delamination factor Fd. In other recent work by Belaadi et al [46], an artificial neural network (ANN) model was developed to evaluate the direct and interaction effects of cutting parameters to analyze delamination. In their experiments, epoxy matrix jute fabric sheets were drilled three times for each cutting condition, and the hole exit damage was measured using a high-resolution scanner.…”

Currently, the manufacture of composite structures often requires material removal operations using a cutting tool. Indeed, since biocomposites are generally materials that do not conduct electricity, electro-erosion cannot be utilized. As a result, the processes that can be used are limited to conventional machining, called chip removal machining, such as drilling.Delamination factors are widely recognized for controlling the damaged area (delamination) induced by drilling in industry. As discussed in the literature, several approaches are available to evaluate and quantify the delamination surrounding a hole. In this context, the objective of this study is to compare the three Fd evaluation methods that have been most frequently used in previous investigations. To this end, three rotational and feed speeds and three BSD tool diameters were selected (L27) for drilling 155 g/m 2 density jute fabric reinforced polyester biocomposites. The response surface methodology (RSM) and artificial neural networks (ANNs) were applied to validate the results obtained experimentally as well as to predict the behavior of the structure depending on the cutting conditions.

“…e fibers traditionally used were carbon, glass, and others. e plastics reinforced with sisal [10,11], jute [12,13], bamboo [14], and porcelain fibers [15], amongst the natural fibers, have attracted attention for their low cost compared to man-made fibers [16,17]. Graphite is a pure carbon in crystalline form, very similar to mica sheets formed tightly by bound atoms [18,19].…”

The advancement of composites mixed with natural fibers and with fillers has become the most supportable alternative material for engineering applications, especially in industries such as automotive and aerospace. Natural fibers are renewable, cheap, biodegradable, and ecological materials. In the present work, already used woven jute fibers, which are extracted from gunny bags with the same grams per square meter (GSM), were used, and then, woven jute fibers were chemically treated to improve their characteristics. Graphite powder-filled used jute fiber reinforced epoxy composite (UJF) are prepared by using the hand-layup technique. Tests such as tensile, flexure, impact, and thermo-gravimetric analysis (TGA) were conducted. These tests were according to ASTM standards to evaluate the effect of graphite filler content on hybrid epoxy jute composites. The composite material is prepared by changing the content by weight of the filler by 3%, 6%, 9%, and 12%. The experimental results reveal that 6% of the graphite composites showed the maximum tensile strength and modulus. With the increase in the filler content, there is a decrease in the flexural properties. The impact resistance increases slightly up to 6% of the filler content. The study of thermal decomposition showed that the lowest mass loss was found at 9% by weight of the filler content. Morphological analysis performed by FE-SEM showed that the addition of filler content improved the binding of the fiber and matrix up to 6% by weight of the filler content. It should be noted that these hybrid composites are a promising material at low cost for lightweight structural applications.

“…However, machining is also an important operation when preparing composite surfaces for bonding assembly for multi-material applications [20]. The machinability of composites mainly depends on the structure and intrinsic characteristics of the bres and the mechanical properties between the bres and the resin responsible for the creation of various defects during machining, especially delamination, cracking, uncut bres and the tearing of bres, which lead to rough surfaces [21][22][23]. In the case of biocomposites with bio bre reinforcement, the mechanical behaviour of the bres must be taken into account since this behaviour is much more prominent than that of the matrix and because of the in uence this behaviour will have on the nal state of the machined part.…”

The present study examined the effects of drilling parameters such as spindle speed (N), feed rate (f), diameter of the tools (d) and drill geometry such as twist drills (HSS-TiN) and brad & spur drills (BSD) used on delamination damage in a biosandwich structure consisting of an epoxy matrix reinforced with bidirectional jute bres and cork (JFCE). Response surface methodology (RSM) and arti cial neural networks (ANNs) were exploited to evaluate the in uence and interaction of the cutting parameters on the delamination factor (F d ) at the output during drilling. In addition, several optimization methods, such as desirability-based RSM, the genetic algorithm (GA) and the fmincon function, were applied to validate the optimal combination of cutting parameters (f, N and d) in the structures studied in biosandwiches during this research. According to the experimental results, severe damage was indeed observed with the BSD tool (F d = 1.684) compared to the HSS-TiN tool (F d = 1.555) for the same cutting conditions. To obtain the minimum F d , the optimum conditions obtained by GA were respectively 1397.54 rev/min, 51.162 mm/min and 5.981 mm for HSS-TiN for f, N and d.
