Abstract The automotive, aerospace, and sports industries are increasingly utilizing hybrid composites made from natural fiber reinforcements. This study evaluated the performance of a composite kenaf pineapple fibers, manufactured using compression molding process, with graphene nanoparticles added at varying weight concentrations 0.5, 1.0, 1.5, 2.0 wt%. Results showed that adding 0.5 wt% increased tensile, flexural, impact strength by 133.75%, 90.24%, 25.67%, respectively. Microstructural analysis revealed integration has enhanced interfacial bond between matrix, creating resin‐rich areas.

Abstract Single fiber polymer composites containing either natural or artificial fibers may not deliver the desired characteristics. The current study used hand‐layup technique to make a hybrid composite by incorporating fiber, Cordia‐dichotoma (CD) and carbon (CF) in polyester matrix compressing mixture for size. investigates influence of loading (0, 5, 10, 15 wt%) on mechanical, structural, crystalline properties CD/polyester keeping total at 20 wt%. Mechanical are investigated with universal testing machine, impact strength using Izod apparatus. Better mechanical (tensile strength‐457.38 MPa; flexural strength‐290.09 MPa strength‐346.46 J/m) were obtained pure arranged four layers (CF/CF/CF/CF), followed (CF/CD/CD/CF) strength‐319.24 strength‐253.03 strength‐291.34 whereas CD (CD/CD/CD/CD) yielded lowest values strength‐117.96 strength‐164.99 strength‐118.11 J/m). Composites undergo hybridization, which improves their properties, lowers cost, makes them more environmentally friendly. characteristics specimens examined Fourier Transform Infrared Spectroscopy (FTIR), X‐ray Diffraction Analysis (XRD), Atomic Force Microscope (AFM), Scanning Electron Microscopy (SEM). According findings, crystallinity index is increased from 77.94% CD/CD/CD/CD 78.21% CF/CD/CD/CF composite. Highest 82.46% was CF/CF/CF/CF These be applications involving medium loads. Highlights In this study, extracted treated alkali (NaOH) reduce biodegradability. To lower cost enhance biodegradable Carbon cordia‐dichotoma have been hybridized. Properties such as tensile, evaluated prepared composites. Hybrid analyzed FTIR, AFM, XRD, SEM assess suitability various applications.
