Hybrid laminated composites consisting of woven kenaf, woven polyester, and polylactic acid (PLA) were fabricated using the hot compression method. The composition and stacking sequence of the hybrid composites significantly influenced their mechanical properties. Increasing the content of woven kenaf improved the flexural properties of the hybrid composites, while the composition of woven kenaf and woven polyester had an effect on flexural strength. Additionally, the tensile fracture surface morphology was evaluated using field emission scanning electron microscopy (FESEM), providing insights for industrial applications.
Hybrid laminated composites were fabricated from woven kenaf, woven polyester and polylactic acid (PLA) using the hot compression method. The hybrid composites consist of woven material as reinforcement having the fiber weight-matrix ratio of 40:60. Six samples of hybrid laminated composites were prepared in different stacking sequences using the hand lay-up method. The laminates were prepared and tested based on ASTM Interna-tional standard method for tensile, flexural and impact properties. S4 samples yield the highest tensile strength, elongation and impact strength among the hybrid composites that were recorded at 103 MPa, 17.88% and 84 kJ/m2, respectively. However, the composition of woven kenaf and woven polyester influenced the result obtained for flexural strength. Higher composition of woven kenaf in hybrid laminated composites exhibited better flexural properties. The tensile fracture surface morphology was evaluated using field emission scanning electron microscopy (FESEM). The data gathered could provide un-derstandings of new hybrid laminated composites for industrial applications such as automotive, structural, and non-structural applications.
