Exploring the Mechanical Impact of Stacking Sequences in Biodegradable Polylactic Acid (PLA) Composites Reinforced with Sisal, Jute, and Kenaf Fibers
摘要
This study explored the impact of varying stacking sequences on the mechanical properties of biodegradable Polylactic Acid (PLA) composites reinforced with sisal, jute, and kenaf fibers. Four distinct stacking sequences (A, B, C, and D) were employed to assess their influence on key mechanical properties. The composites were fabricated with a consistent PLA matrix, incorporating different arrangements of Sisal, Jute, and Kenaf fibers. Among the findings, Sequence D emerged as notable, showing the highest tensile strength (63.5 ± 2.7 MPa), modulus (4.3 ± 0.2 GPa), flexural strength (80.1 ± 3.7 MPa), modulus (4.7 ± 0.4 GPa), Shore D hardness (82 ± 5), impact strength (145 ± 12 J/m2), and interlaminar shear strength (14.5 ± 1.3 MPa). These results offer valuable insights into tailoring the mechanical performance of biodegradable PLA composites contributing to the ongoing quest for sustainable materials across various industries.
