AI Article Synopsis
- This study explores how the stacking sequence and ply orientation affect the mechanical properties of pineapple leaf fiber (PALF) and carbon hybrid laminate composites.
- The researchers used a vacuum infusion technique to create laminates with varying configurations, including cross-ply symmetric, angle-ply symmetric, and quasi-isotropic designs.
- Results indicated that laminates with interior carbon plies showed the highest tensile strength, while those with exterior plies had the best flexural properties; failure typically began at the weakest PALF layer and involved several failure modes such as fiber pull-out and delamination.
Article Abstract
In this paper, the effects of stacking sequence and ply orientation on the mechanical properties of pineapple leaf fibre (PALF)/carbon hybrid laminate composites were investigated. The hybrid laminates were fabricated using a vacuum infusion technique in which the stacking sequences and ply orientations were varied, which were divided into the categories of cross-ply symmetric, angle-ply symmetric, and symmetric quasi-isotropic. The results of tensile and flexural tests showed that the laminate with interior carbon plies and ply orientation [0°, 90°] exhibited the highest tensile strength (187.67 MPa) and modulus (5.23 GPa). However, the highest flexural strength (289.46 MPa) and modulus (4.82 GPa) were recorded for the laminate with exterior carbon plies and the same ply orientation. The fracture behaviour of the laminates was determined by using scanning electron microscopy, and the results showed that failure usually initiated at the weakest PALF layer. The failure modes included fibre pull-out, fibre breaking, matrix crack, debonding, and delamination.
