This study demonstrated the reinforcing potential of kenaf core fiber (KCF) to complement and sustain oil palm fiber supply chain in the production of natural fiber-thermoplastic biocomposites. The lignin-rich KCF was incorporated into cellulose-rich oil palm empty fruit bunch fiber (EFBF)- and oil palm mesocarp fiber (OPMF)-poly(lactic acid) (PLA) composites, aimed at achieving synergism. The hybrid biocomposites developed by melt blending and subsequent compression molding were characterized for possible application as an alternative to medium-density fiberboards. The mechanical properties and dimensional stability of both single fiber- and hybrid fiber-PLA biocomposites were evaluated and compared. The test results showed a synergistic improvement as a consequence of fiber hybridization. Also, the findings suggested the best material performance with the incorporation of 5% KCF into 55% EFBF or OPMF and 40% PLA matrix. The OPMF-KCF-PLA hybrid biocomposites gave better results than the EFBF-KCF-PLA hybrid biocomposites.
