“…A minor discrepancy was detected between the numerical and experimental results. Similarly, in another work Sathishkumar et al 28 had studied the 3D approach for analyzing the tensile and flexural properties of fly ash was used as filler material in sisal/epoxy composites through ANSYS Workbench. The finding reflected that, the rule of mixture model (ROM) yielding more accurate result than that of Halpin-Tsai model while evaluating mechanical performances.…”

Owing to the crucial qualities such as strength, stiffness and durability, as well as low-cost manufacturing benefits, the fibre-reinforced composite materials are becoming more popular in structural applications. The current work basically focused on the influence of Pistachio shell particles (PSP) on mechanical performances of kenaf(K)/glass(G)/polyester hybrid laminates. Usual hand layup technique is used to fabricate different stacking order laminates such as KKKK, KGGK, GKKG, KGKG, and GGGG with PSP filler concentration of 1 wt%, 3 wt% and 5 wt%. The experimental findings reflect a noticeable improvement in mechanical properties with gradual inclusion of PSP filler. The KGKG laminate with 5 wt% of PSP shows an optimum tensile strength of 127.35 MPa and highest micro-hardness value of 21.35 HV, whereas KGKG laminate with 3 wt% of PSP exhibits a maximum flexural of 112.42 MPa and impact strength of 75.59 KJ/m2. The numerical analysis is also been carried out to validate the experimental results using ANSYS 19.0 software. On comparing the data of numerical analysis with experimental values, the deviation of result is found to be within the limit of 5% to 10%. Furthermore, the result of Thermo Gravimetric Analysis (TGA) has shown a highest amount of residue of 31.22% at 700°C in case of GKKG laminate with 5% of PSP filler. Again, at 5 wt% of PSP filler, the GKKG laminate has shown a lower water intake capability of 3.5% in comparison to KGKG and KGGK laminates at saturation time of 14 days. The fractography study has been conducted to examine the different mode of failure of laminates during testing by the help of Scanning Electron Microscope (SEM).

“…One of the most common numerical methods used in the analysis of natural fiber composites is finite element analysis (FEA). The FEA has been used to study the mechanical properties of various natural fiber composites, including those reinforced with kenaf [28], sisal [29], banana [30], coir, bamboo, and hemp [31] fibers. Earlier researchers focused on the analysis of different hybrid NFPMCs using numerical and experimental methods, specifically investigating the tensile properties [32] and mechanical behaviour [33].…”

The present work deals with the mechanical characteristics and deflection responses of novel partially biodegradable hybrid composites embracing an animal based (Human Hair), a plant based (Luffa Cylindrica) fiber (denoted as HHF and LCF) and Incense Stick Ash (ISA) under different loadings. Ultrasonicator assisted hand lay-up technique has been followed for the inhouse fabrication process by incorporating epoxy resin as the matrix material while varying weight ratios (0, 5, 10, 15, and 20 wt.%) of ISA filler. Firstly, the density, elastic properties through non-destructive Impulse Excitation Technique (IET), microhardness, strengths under tensile, bending and impact loading are obtained and the surface morphology of fractured surfaces is studied. The composite filled with 10 wt.% ISA shown the best overall tensile, bending and shear properties, while the highest flexural strength and microhardness is depicted by composite filled with 20 wt.% ISA. Subsequently, finite element (FE) analysis using a simulation model in ANSYS is employed to acquire the tensile and flexural strength, those are found to be comparable with the experimental values. Finally, a higher-order nonlinear FE model is developed and implemented using MATLAB programming platform to compute the static responses under different loads (point load, sinusoidally distributed line load, uniformly distributed line load, uniformly distributed load and sinusoidally distributed load) using the experimentally obtained composite material properties. The validity of the developed model has been tested by comparing the results with the data acquired through lab-scale experimentation. From the numerical illustrations, moderate ISA filled (10 wt.%) composites with higher aspect ratio and lower thickness ratio are observed to provide more significant resistance to deflection under static loading.

“…The results stated that the variation of Poisson's ratio values did not affect the finite element analysis results. Sathishkumar et al [47] studied the experimental and numerical analysis of filler material on sisal-fiber-reinforced polymer composites. The mechanical properties were tested by using flexural and tensile tests.…”

The impact of matrix material on the mechanical properties of natural-fiber-reinforced hybrid composites was studied by comparing their experimental, and numerical analysis results. In the present work hemp and flax fibers were used as reinforcement and epoxy resin and ecopoxy resin along with hardener were used as matrix materials. To study the influence of the matrix material, two sets of hybrid composites were fabricated by varying the matrix material. The composite samples were fabricated by using the compression-molding technique followed by a hand layup process. A total of five different composites were fabricated by varying the weight fraction of fiber material in each set based on the rule of the hybridization process. After fabrication, the mechanical properties of the composite samples were tested and morphological studies were analyzed by using SEM-EDX analysis. The flexural-test fractured specimens were analyzed by using a scanning electron microscope (SEM). In addition, theoretical analysis of the elastic properties of hybrid composites was carried out by using the Halpin–Tsai approach. The results showed that the hybrid composites had superior properties to individual fiber composites. Overall, epoxy resin matrix composites exhibited superior properties to ecopoxy matrix composites.
