| Date Issued | 12 August 2024 |
| Abstract | Abaca fiber reinforced polymer composites hold immense potential for structural applications, necessitating a comprehensive understanding of their mechanical behavior. As the demand for environmental-friendly materials grows, this study endeavors to revolutionize the understanding of abaca fiber reinforced polymer composites through the development and validation of a finite element model (FEM) for a composite beam made from 30% abaca fiber reinforced polymer, with dimensions of 135 mm in length, 12.7 mm in width, and 3 mm in thickness. The FEM was developed using Ansys Composite PrepPost, incorporating accurate material properties and boundary conditions. Mesh independence analysis confirmed convergence at 312 elements. Structural responses were simulated under bending loads and pure moment, considering two fiber orientations: 0 deg/90 deg and +45 deg/-45 deg. Experimental validation involved fabricating the beam with the hand lay-up technique, and testing it under various loads to measure flexural and torsional deflections. The results showed that the FEM accurately predicted the beam's performance, with the 0o/90o orientation exhibiting higher flexural deflection and the +45deg/-45deg orientation showing greater torsional deflection. The trend of the results are also in agreement with the analytical calculations based on the Composite Lamination Theory (CLT). Statistical analysis confirmed that the differences between experimental data and FEM predictions were not significant, validating the model's reliability. While the findings are promising, caution should be exercised in generalizing the results due to the small sample size. Overall, this study underscores the FEM's potential for advancing the utilization of abaca fiber composites in engineering, ensuring reliable and efficient modeling for practical applications. |
