Abstract

This study aims to analyze the effect of variations in luffa (Luffa acutangula) fiber length on the tensile properties of Polyester resin matrix composites. The composites were made by hand lay-up using a volume fraction of 90% resin and 10% fiber, with fiber lengths of 5 mm, 7 mm, 9 mm, and 11 mm, and tested using a UTM according to ASTM D638. The results showed fluctuating mechanical properties, with the highest tensile strength and maximum stress at 9 mm (0.816 kN and 20.31 MPa) and the lowest at 7 mm (0.681 kN and 17.27 MPa). The highest strain occurred at 9 mm (0.019) and the lowest at 5 mm and 7 mm (0.015), while the highest modulus of elasticity was at 5 mm (1387.610 MPa) and the lowest at 11 mm (970.5158 MPa). Overall, a fiber length of 9 mm is the optimum condition because it produces the best balance between strength and deformation.

Abstract

This research analyzes the structural strength of an adjustable spreader carbody for Electric Multiple Unit (EMU) trains under a 40-ton load to determine the most optimal and efficient material for manufacturing at PERUSAHAAN KERETA API (Persero). The study employs Finite Element Analysis (FEA) static structural simulation using Ansys Workbench, based on a 3D model created in Autodesk Inventor. The spreader's most critical condition at a 4000 mm length was evaluated across three material variations: SS400, SM490A, and S355J2+N steel. Simulation results indicate that all materials are structurally safe, exhibiting maximum von Mises stresses between 106.96 MPa and 107.18 MPa, well below their respective yield strengths. Total deformation remained minimal at under 0.08 mm, and the minimum safety factors ranged from 2.94 to 3.22, satisfying the industrial standard of 2.5 to 3.0 for lifting equipment. Although S355J2+N offers the highest safety margin, SS400 is identified as the most optimal and efficient choice. It provides an adequate safety factor of 3.011, minimal deformation, superior cost-effectiveness, and broad market availability, ensuring safe and economical lifting operations without compromising structural integrity.
