“…Long Continuous Bamboo fiber of 15µm fiber diameter with Young's modulus 9.8GPa and Tensile Strength 262MPa is considered as reinforcement, while Epoxy resin with Young's modulus 3.3GPa and Tensile strength 54.6MPa is considered for matrix [19]. For validation, the experimental values from reference [17] [18] with similar fiber and matrix values are taken into account.…”

“…The paper investigates the unidirectional Bamboo Fiber Reinforced Epoxy Resin Composite (BFRC) for elastic constants using different theoretical methods like the Rule of Mixture (ROM) [3][15], a combination of Cox and Voyiadjis' Modified Rule of Mixtures (MROM) [6][7] [16], Halpin-Tsai model [5][3][16], Chamis model [4] [15] [16], Huang's Unified Bridging Model [10] [16], and Christensen's Elasticity approach methods [9] [15], along with FE homogenization model using RVEs of square, diamond, and hexagonal fiber arrangement. As a validation, the predicted elastic coefficients are then compared with experimental data from available literature [17] [18].…”

Natural Fiber composites are among the potential materials due to their low cost, biodegradability, environmental concerns, and other merits. This paper investigates various theoretical methods to evaluate the elastic behavior of Bamboo fiber-reinforced Epoxy composite and compare it with available experimental data. To compute elastic properties for different fiber volume fractions, prominent micromechanical models such as the Rule of mixing, Halpin-Tsai, Chamis, Unified Bridging, and Elasticity approach, as well as the most current FE homogenization simulation, are employed. FE simulation results from the advanced ANSYS 21.0 material designer module incorporating different Representative Volume Elements (RVE) (Square, Diamond, and Hexagonal) are compared with these models. Through this, a comparative analysis is provided for the validity of different models in predicting the elastic behavior of similar natural fiber-reinforced composites.

“…NFRC have been increasingly applied in some manufacturing industries such as automotive [1,2], marine [1] and construction [1][2][3]. Consequently, many tests have already been done to describe mechanical properties of the NFRC including tensile strength [1], compression [1,4,5], flexural [1,5], torsion [5][6][7], impact [4], moisture [4], fracture [4] and fatigue [4]. In the case of fatigue, the most usual test to investigate fatigue behavior of composite materials is the tension-tension loading [4,8].…”

Natural fibers are low-priced, abundant and renewable. The application of natural fiber to reinforced polymers materials can reduce cost, decrease weight and increase the mechanical properties of the composites. Many studies were carried out in natural fibers reinforced polymer composites using different natural fibers, one of those is bamboo fibers. Nevertheless, torsional fatigue tests have not been applied to predict the mechanical behavior of the bamboo fibers reinforced polymer composites. In this study, bamboo fiber reinforced epoxy resin composites were molded by compression in a rectangular mold. These specimens were machined according to the schematic of thin-walled tubular specimen suggested by ASTM-2207-15 and tested in torsional fatigue loading with R=−1. A mechanical torsion fatigue testing machine was constructed to perform torsion test with constant amplitude of the twist angle. An angle measuring device was constructed to measure the angular displacement in the useful region of the specimens (gage length). Torsional fatigue life curves were plotted for pure epoxy resin, unidirectional and discontinuous bamboo fibers reinforced epoxy resin composites. Pure epoxy resin specimens presented the longest torsional fatigue life and the poorest results were found in discontinuous bamboo fibers composites. The experimental results suggest that the epoxy resin is strongly related to the torsional fatigue behavior of the composite materials. The fracture surface of test specimens often showed that cracks occurred in the interfacial region of the composites.
