Abstract

The objective of this research is to produce and analyze natural fiber-based composites (sisal/polyester, kenaf/polyester, pineapple/polyester) and their hybrid composites (sisal/kenaf/polyester, kenaf/pineapple/polyester, and sisal/kenaf/pineapple/polyester) made by compression molding. These composites were characterized mechanically using hardness (shore D), tensile, flexural, and impact (Charpy) tests. Fiber matrix bonding was analyzed using Scanning Electron Microscopy (SEM). Among all the fiber-based samples (sisal/polyester, kenaf/polyester, and pineapple/polyester), sisal/polyester shows a high hardness value of 93.24 S_d, a tensile strength of 43.00 MPa, and an impact strength around 7.42 kJ/m², while pineapple/polyester produces a better flexural strength of 83.21 MPa. Hybrid composites showed improved mechanical performance. The mechanical characteristics of the sisal/kenaf/pineapple/polyester hybrid composite were 56.16 MPa, 1.71 GPa, and 9.34 kJ/m². The highest flexural strength of the Sisal/kenaf/polyester multi-layered samples was observed as 83.24 MPa.
