Exploring tensile properties of bio composites reinforced date palm fibers using experimental and Modelling Approaches
The objective of this study was to assess the tensile strength of epoxy bio-composites reinforced with palm fibers, both untreated and treated with sodium carbonate NaHCO3 at a concentration of 10 % (w/v) for 24 and 96 h, with varying weight percentages of fibers (15 %, 20 %, 25 %, and 30 %). To predict the mechanical performance of the composites, two methods were employed: artificial neural network (ANN) and response surface methodology (RSM). A Box-Behnken RSM design was used to conduct experiments and establish a mathematical model of the bio-composite behavior as a function of the fiber percentage in the samples, specimen cross-section, and treatment time. The ANN forecasts showed consistent expected values for the bio-composite sample behavior, with a correlation coefficient (R2) greater than 0.98 for Young's modulus and 0.97 for stress. Similarly, the correlation coefficients obtained by RSM for the mechanical properties were also highly satisfactory, with an R2 of 0.89 for Young's modulus and 0.87 for stress. Finally, the errors generated by each method (Box-Behnken and ANN) were compared to the experimental results.

Modelling and optimization of the absorption rate of date palm fiber reinforced composite using response surface methodology
The aim of this work to explore the absorption behavior of bio composites reinforced with date palm fibers. RSM and ANOVA were utilized to evaluate the impact and interdependence of input variables (Time: from 24 h to 672 h, Fiber content: 15 %, 20 %, and 25 %, and types of water: seawater, distilled water, and rainwater) on the output variables (Mass of CDPF) during a water absorption process that lasted more than 670 h at 23 °C. The findings revealed that the bio composites with the above-mentioned filler content absorbed more water as the amount of fibers increased, with absorption rates of 14.03 %, 19.39 %, 30.94 % for seawater, 15.42 %, 20.64 %, and 36.08 % for distilled water, and 16.37 %, 21.98 %, and 42.10 % for rainwater, respectively. Additionally, the study measured the diffusion coefficient of bio composites, which had a minimum value of about 2.11 × 10−6mm2/s and a maximum value of about 3.99 × 10−6mm2/s. The results of RSM model analysis showed that this model is accurate and reliable. Where the values of R2 and adjusted R2 coefficients for the Mass of CDPF were 99.63 % and 99.61 %, respectively, indicating an ideal match between experimental and predicted values. These findings provide valuable information for engineers interested in incorporating date palm fiber bio composites during development and implementation.

INVESTIGATION OF MACHINABILITY OF BIOCOMPOSITES: MODELING AND ANN OPTIMIZATION
The This work studies the drilling performance of bio composites reinforced with cellulosic fibres. The drilling was carried out at three spindle speeds and at three feed rates using three dissimilar drills namely: HSS-TITAN, HSS-CARBIDE, and HSS-SUPER. The drilling performance was evaluated in terms of the delamination factor which was determined using the free software image J. The results showed that the value of this factor decreased with increasing spindle speed and increased with increasing feed rate. On the other hand, the HSSSUPER drill causes less delamination than the other two drills. To predict the delamination value, the artificial neural network (ANN) method was used. The best hole quality was obtained when using the HSS-SUPER drill, with a spindle speed of 2200 rpm and a feed rate of 40 mm/rev. The worst case was brought when using an HSS-carbide drill, with a spindle speed of 500 rpm and a feed rate of 120 mm/ rev

Assessment of induced delamination drilling of natural fiber reinforced composites: a statistical analysis
This work focuses on the study of the drilling performance of bio composites reinforced with date palm fibers (CDPF). It is a new fiber that is characterized in terms of piercing behavior for the first time. The experimental study was carried out with three types of drills, with a diameter of 10 mm and feed and spindle speeds of the order of (40, 80 and 200 mm/min) and (560, 1120 and 2240 rpm), respectively. The drilling performance was assessed in terms of delamination and surface quality, such as circularity and cylindricity of the drilled holes. Using the CMM machine, the value of the delamination factor was determined using Image J software. The results showed that the value of the latter increased with the increase in feed rate and decreased with the increase in spindle speed. The delamination factor has maximum and minimum values of approximately 1.98 and 1.01 respectively. For the first time, RSM and ANOVA were used to assess the influence and interaction of input parameters (cutting conditions) on the output parameters (delamination factor Fd) during drilling of CDPF. The results obtained help manufacturers, to choose the most appropriate machining conditions to achieve better machinability for other newly developed NFRCs in the aeronautical and defense industry where the substitution of the synthetic fibers by the natural fibers becomes inevitable for economic reasons.

Experimental Investigation of the Absorption Behavior of Date Palm Fiber Reinforced Iso-Polyester Composites: Artificial Neuron Network (ANN) Modeling
The present article attempts to study absorption properties of bio-composites reinforced with date palm fibers. The effect of fiber loading on water absorption at room temperature 25°C was investigated. The weight gain was measured of bio-composites immersed in distilled water, seawater and rainwater, for more than 670 hours, until reaching the saturation with a measurement interval between 24 and 48 hours. To understand absorption phenomenon, scanning electron microscopy was used. Porosity rate was determined using image J software. It was noted the water absorption rate of the bio composites reached 16.20%, 16.33%, 21.94%, 41.99% for seawater, 16.41%, 16.52%, 20.84%, 30.08% for distilled water, and 14.00%, 14.04%, 19.30%, 36.94% for rainwater, respectively. The absorption increases when increasing fiber content. The diffusion coefficient of bio-composites has minimum and maximum values of about 1.94 × 10−6mm2/s and 3.99 × 10−6mm2/s, respectively. Palm fibers are highly porous. The porosity value was higher than 51%. To predict the absorption rate, artificial neural network method was used. The ANN models obtained are very well correlated with the experimental data where the values of the correlation coefficient of the datasets are all beyond 0.99 and the average error value was estimated at 3 × 10−5.

Investigation of machinability of biocomposites reinforced by natural fibers: artificial neuron network (ANN)
The machining of bio composites takes a significant place in scientific research to determine their applicability in many industrial applications. Some of the famous operations in this field are exterior trimming, interior trimming, grooving or slotting, and drilling. The latter is a cutting process that uses a drill bit to cut a hole of a circular cross-section in solid materials to facilitate the final assembly of parts in the manufacturing industry as this process requires fine-tuning to achieve high hole quality. This work focuses on the study of the drilling performance of bio composites reinforced with lignocellulose fibres - Date Palm -. The drilling was carried out at three spindle speeds of 500,1100 and 2200rpm and at three feed rates of 40, 80 and 120 mm/rev using three dissimilar drills of Ø 10 mm namely: HSS-TITAN, HSS-CARBIDE, and HSS-SUPER. The drilling performance was evaluated in terms of the delamination factor which was determined using the free software image J. The results showed that its value increased with increasing feed rate and decreased with increasing spindle speed. On the other hand, the HSS-SUPER drill causes less delamination than the other two drills. To predict the delamination value, the artificial neural network (ANN) method was used assisted by MATLAB software. The best hole quality was obtained when using HSS-SUPER drill, with a spindle speed of 2200 rpm and a feed rate of 40 mm/rev. Whereas, the worst case was obtained when using HSS-carbide drill, with a spindle speed of 500 rpm and a feed rate of 120 mm/ rev.

Study and numerical simulation of the stress intensity factor of cracked plates
Metal structures are actually very rarely perfect. There is a wide variety of defects that play a fundamental role in the properties of materials. The presence of defects in aluminum plates is of great importance in the field of modern technology structures and mechanical engineering, given their use for the assembly of different structures by riveting, screws or bolts. However, the drilling of these holes increases the probability of the presence of cracks and reveals damage of a different nature in these structures which affect the life of these mechanical systems. To try to understand this phenomenon, our work consists in simulating the propagation of a crack in an Aluminum plate of the 2024-T3 series, this type of material is commonly used in construction, automotive, aviation and spacecraft applications due to their good balance between lightness and good mechanical properties. The numerically tested 3D plate has cracks in different positions (bottom, middle and top), it is embedded on one side with an evenly distributed force on the other side. Two finite element methods are used, that of the contour integral where it was concluded that the values of the SCF (stress concentration factor) given by the FEM methods are close to those calculated and that the stresses, forces and energies are maximum next to the extremities of the crack (crack type). The coherent J integral obtained by finite element analysis, while the results of the calculation of 5 integral paths for three types of samples showed that the relative error was 17.7% between the absolute value ΔJ avg.

The effect of fiber orientation on the thermo mechanical properties of bio composites
This study presents a method to determine the thermo-mechanical properties of bio-composite parts reinforced with natural fibers. Three orientations according to well-defined angles (15°, 30° and 45°) are used with an Abaqus computer code and the Python programming language. The influence of different fiber orientations in representative volume elements has been demonstrated when analyzing heat transfer in fiber-reinforced polymer composites. Finite element method (FEM) simulations were performed to model and visualized 2D and 3D microstructures of natural fiber reinforced matrix composites with heat transfer and mechanical property boundary conditions. The results indicate that the microstructural heterogeneity influences the rates of thermo-mechanical properties and therefore overall, the conduction of the composite is affected by the orientation of the fibers in the matrix

Analysis of the effect of cutting conditions for circularity and cylindricity errors for drilling bio composites
This work focuses on studying the drilling performance of bio-composites with a palm fiber reinforcement fraction of 40 wt%. The drilling was carried out under dry cutting conditions at three spindle speeds of 500,1100 and 2200rpm and three feed rates of 40, 80, and 120 mm/rev using three 10 mm diameter drills: T1: HSS-TITAN, T2: HSS-CARBIDE, and T3: HSS-SUPER. The drilling performance was evaluated in terms of the circularity and cylindricity of holes that were determined using a CMM device applying the technique of contact scanning. The results showed that the effect of feed rate was greater than spindle speed. It is found that an increase in the feed rate value results in a degradation of circularity and cylindricity: For holes drilled under the following cutting conditions (N=500rpm, ƒ=40mm/rev, and T=T1). The circularity and cylindrical values was 0.0301 and 0.0475 respectively. On the other hand these values rise to 0.0740 and 0.1717, respectively, when drilling under cutting conditions (N = 500 rpm, ƒ = 120 mm/rev and T = T1). It was observed that holes drilled using coated tools (T1 and T2) produced fewer errors than the uncoated tool (T3). The circularity and cylindricity have minimum and maximum values of approximately 0.0180, 0.0852 for circularity, and 0.0475, 0.554 for cylindricity.

MANUFACTURING OF RAPID PROTOTYPES OF MECHANICAL PARTS USING REVERSE ENGINEERING AND 3D PRINTING
This article focuses on the design and manufacture of mechanical parts that have complicated shapes using the technique of reverse design using a scanner or an MMT for data acquisition in the form of a point cloud, using CAD software (CATIA). The digital model created is used for a virtual representation of the final product. Then we get the physical model on a 3D printer (also called additive manufacturing process) for later use in sand moulds. To have the imprint in the sand mould, we go through the fusion of the physical model (part). The use of this technique in the industry, allows us to save a lot of time in terms of model preparation and simple to implement, especially if it is mechanical parts that do not have a definition drawing, or they are worn out, then structural analysis was applied on the model using FE based software and tools to prove the quality of the product. Von Mises equivalent strains and stresses were predicted and decreased with increasing areas and honeycomb thickness. The objective of this article is to give an overview of this relatively modern technology and its various applications.
