Natural fiber composites are capable of replacing synthetic fiber composites in aeronautics, transportation, architecture, and sports. This work used epoxy matrices to produce natural hybrid fiber composites from hemp, pineapple, and palm fiber. To choose the best material for a design or component, a thorough and successful approach is needed. Material selection judgments are best handled by multi-criteria decision-making (MCDM) procedures. Integrated MCDM approaches like AHP, TOPSIS, and MOORA rank epoxy-hemp-pineapple-palm fiber composites. TOPSIS and MOORA use AHP weights to rank objects. AHP weights are used to rank objects in both the TOPSIS and MOORA methods. Selection is based on a variety of properties of the generated composites, including water absorption and specific heat capacity, in addition to density, hardness, tensile strength, and toughness. The thermal degradation of fiber polymerization is assessed by thermo-gravimetric analysis (TGA). According to a thorough evaluation of MCDM methodologies, a hybrid composite made of palm, hemp, and pineapple performed best, followed by a hybrid composite made of palm and pineapple. This study found that a palm fiber composite has subpar results. Scanning electron microscopy (SEM) is used to examine fiber form and interfacial bonding in composite samples that have been exposed to tension fracture.
