Comparative Analysis of Mechanical Properties in Cross-Ply and Angle-Ply Pineapple Leaf Fiber (PALF) Composites
摘要
This study examines the mechanical characteristics of two different composite structures derived from Pineapple Leaf Fiber (PALF): Cross-Ply and Angle-Ply configurations. PALF underwent treatment with an alkaline solution to augment its properties. Employing a vacuum infusion technique, the composites were fabricated and subjected to assessments for both tensile and flexural performance based on the ASTM D3039 and ASTM D7264 respectively. Results indicate that the Cross-Ply configuration surpassed the Angle-Ply in terms of tensile strength and strain, while the Angle-Ply exhibited superior flexural strain albeit with lower flexural stress. Cross-ply configurations exhibited superior flexural strength of 110.79 MPa, whereas an-gle-ply configurations showed a higher tensile strength of 63.76 MPa. Throughout testing, various failure modes were observed, including fiber pull-out, fiber breakage, matrix cracking, debonding, and delamination. These findings contribute to elucidating the impact of fiber orientation on PALF composites and suggest potential applications across engineering domains.
