“…When considering the drilling of composites, hole quality results are mainly fibre related [8]. The development of thrust forces during the drilling operation is accepted to be more related with the drill geometry, feed rate and spindle speed, as already demonstrated in several published studies by different authors, see [9][10][11][12][13][14][15][16][17][18][19][20], showing the importance of parameter selection for the minimization of machining damages. In [11] Khashaba suggested a new approach to the drilling of woven glass fibre-reinforced polymer (GFRP) composites: clamping the specimen with two support plates, thus controlling force at drill entry and exit sides.…”

Composite materials are used in a substantial number of products. Environmental concerns highlight the need for the inclusion of recovered waste in their formulation, thus reducing their carbon footprint. These solutions raise the need to confirm the mechanical characteristics of these materials, avoiding unwanted failures. In this work, the authors present an experimental study on the drilling effects on fibrous–particulate hybrid composites made of glass/carbon fabrics and three different micro-inclusions: silica particles, recycled carbon fibre powder and cement. The mechanical features of the plates are confirmed by thrust force monitoring during drilling and by flexural testing. The range of results confirm the mechanical outcomes due to machining. The plates with monolithic carbon fabric or with carbon fabric plies in the outer plies returned higher mechanical characteristics. The plates with micro-inclusions had enhanced the flexural strength by 23% and 10%, in 40% and 60% fabric plates, respectively. The results demonstrate that the use of alternative formulations with micro-inclusions from recovered waste can contribute both to the reduction of the mechanical degradation of drilled hybrid composites and to environmental purposes by avoiding the increase in landfill waste.

“…Natural fiber-reinforced polymer (NFRP) has been a trend in composite materials research and engineering (John et al, 2008). It offers the biodegradable advantages of a composite (Lotfi et al, 2019) and the comparable mechanical strength (Holbery and Houston, 2006) to the conventional synthetic ones (Faruk et al, 2012). Polylactic acid (PLA) is a biodegradable polymer that has become the most pledging biodegradable material that has been used as a matrix in a composite material due to its vulnerability to bacteria (Siakeng et al, 2019).…”

The fabrication of a natural prepreg with poly-lactic acid (PLA) matrix and ramie fiber reinforcement was engineered on a laboratory scale by impregnating the unidirectional and bidirectional ramie fiber with PLA matrix solvent on a glass die. The obtained composite prepreg has been stored at a very low temperature to maximize its shelf life. Tensile and biodegradability tests of the composite laminates prepared by the hot-pressing method have also been conducted. Tensile test results show that the freezer-stored bidirectional 0/90° prepreg laminate specimen has the highest tensile strength of 71.44 MPa with a modulus of 2.70 GPa on average. Meanwhile, the unstored bidirectional 0/90° prepreg laminate specimen has the highest level of elasticity, with a modulus of 1.29 GPa on average. The biodegradability test shows the decomposition process of the composite laminate under actual composting conditions. Microscopic observation of the damaged specimen results shows good adhesion between the PLA matrix and ramie fiber and the decomposition of the biodegradability test samples.

“…Currently, a wide variety of plant fibers are currently used as reinforcements for different matrices [7,8], such as sisal. [9], jute [10], Agave americana L. [11], flax [4,[12][13][14], Washingtonia filifera [15], date palm [16,17] and pineapple [18].…”

“…A constant dill (8 mm HSS) was used to perform the drilling process. The obtained results suggest that a better dimensional stability was reached by using a 30% by weight of fiber treatment for 8 h. Recently, Lotfi et al [14] examined the drilling performance of a developed high-strength NFRC laminate (flax/PLA) and evaluated the influence of the cutting parameters, feed rate and spindle speed using two drills (HSS twist drill and carbide drill) on the generation of the minimum drilling force and drilling-induced damage. The authors concluded that the lowest damage with a good quality of the hole of the flax/PLA biocomposite is achieved with the HSS twist drill, a spindle speed of 2550 rpm and a feed rate of 0.08 mm/rev.…”

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.
