“…In turn leads to inadequate bonding between the selected three various constituents (epoxy, carbon fiber, and ceramic particles), then the loads may not be conveyed efficiently from one end to another and as a result, there is a drop in tensile strength of the hybrid composites. These findings agree with previous studies [3,7,33] and also were verified by the observed morphology for the fracture surfaces of the tensile test samples. Fig.…”

“…The simultaneous use of fibers and fillers in a polymer matrix results in the formation of a hybrid compound [5]. Reinforcement increased the mechanical characteristics of the polymeric composite, resulting in the formation of a hybrid polymeric composite composed of polypropylene reinforced with graphene nanoplatelets (GnPs) and Titanium dioxide (TiO2) [6].Carbon fiber reinforcement of polymers has recently gained prominence due to its better mechanical qualities, such as strength-to-weight ratio, hardness-to-weight ratio, and chemical resistance [7]. One of the researchers employed carbon fibers to reinforce the airframe's scarf adhesive joints, as well as Sic and Al2O3 nanoparticles mixed with epoxy resin.…”

Hybrid polymer composites have recently become the interest of the world and their uses are increasing in various applications, especially mechanical, electronic, and other applications. Recently, advanced machining techniques for hybrid polymer composites have been used to solve many problems during machining processes, including the ability to form complex shapes, high performance, better surface features, and high levels of accuracy. Among many machining processes, Abrasive Water Jet Machining (AWJM) has attracted the attention of many researchers and engineers in many industries. In this study, hybrid polymer composites consisting of an epoxy matrix reinforced with six layers of carbon fibers with a fixed percentage (15%) and ceramic particles (SiC and Al2O3) with different weight percentage were prepared by hand lay-up method. Mechanical tests including (tensile test, flexural test, impact and hardness test) were conducted. The results of mechanical tests showed that an improvement in the tensile and flexural properties was of (19.7%) in the tensile strength, (40%) in the modulus of elasticity, )55.26%( in the flexural strength and ) 69.49%( in the flexural modulus, )12%( in the hardness using hybrid polymer constituent (70 wt% Epoxy+15 wt% CF +10 wt% Sic +5 wt% Al2O3). However, this hybrid polymer constituent includes lowest value of impact strength. Also, the morphological analysis indicated the uniform distribution of particles, the best defect-free surface and the bonding strength between the reinforcement and the epoxy matrix can be obtained using this constituent which has contributed to the improvement in the mechanical properties. The AWJM automation process was also performed based on design of experiment (Taguchi L18 design) to study the effect of the selected AWJM parameters (the hybrid polymer constituents, transverse velocity, stand of distance) on the different response variables (surface roughness, hardness, and kerf width). The analysis of variance (ANOVA) concluded that the hybrid polymer with the constituents (70 wt% Epoxy+15 wt% CF +10 wt% Sic +5 wt% Al2O3) has the most influential factor on the responses followed by transverse velocity, and then stand of distance. Moreover, the grey relational analysis was beneficially used to determine the multi optimization of AWJM parameters.

In this research, the effect rates of independent variables (multi-walled carbon nanotube wt. % content, cutting speed and feed rate) on the dependent variable (thrust force) used during drilling of glass fiber reinforced polymer (GFRP) composite were examined and optimum drilling condition was established. Drilling experiments were performed considering the Box-Behnken Design of the Response Surface Methodology (RSM). As a result of variance analysis, the effects of drilling parameters and the effects of interactions on thrust force were determined. A mathematical model was developed for the thrust force by using independent variables. Optimum drilling parameters were determined by using Desirability Function Analysis (DFA). Finally, verification experiments were carried out. Figure A. Experiment flow chartPurpose: The main objective of the study is to correlate drilling parameters with thrust force during the drilling of the GFRP composite materials using RSM. The development of a mathematical model is adopted to predict the thrust force. The final aim of this study is to optimize drilling conditions using DFA. Theory and Methods:The optimization is based on RSM and DFA. Moreover, the analysis of variance (ANOVA) is used to establish the statistical significance of the drilling parameters on thrust force. Results:The results indicated that the thrust force is powerfully affected by feed rate with a large contribution, followed by cutting speed and weight percentage of muti-wall carbon nanotube. The RSM allowed the optimization of the drilling conditions for minimal thrust force. Conclusion:Adjusted R 2 value calculated for the response surface model was found to be 0.9950, which means that the variance in thrust force could be explained by the significant factors determined. The average absolute error between experimental and predicted values was calculated as about 0.90% sufficiently low to verify the high predictive strong of model. After developing the mathematical model, a numerical optimization technique using DFA was employed to optimize the drilling process. Minimum thrust force parameters were obtained as 0.99 wt % MWCNTs, 71.47 m/min cutting speed and 0.10 mm/rev feed rate by using RSM and DFA.

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.
