Abstract: This study investigates the development of natural rubber (NR) composites reinforced with cellulose fibers extracted from coconut husk (CHp) waste. Cellulose dispersion within the rubber matrix was enhanced via liquid-phase mixing using latex aqueous microdispersion. Cellulose was isolated using an alkaline treatment, effectively removing hemicellulose and lignin, verified by FTIR analysis. The NR composites were prepared by incorporating either alkali-treated CHp or untreated CHp with natural latex masterbatch as the reinforcing agent, using a two-roll mill. The reinforcing agent content ranged from 2.5 to 10 wt.%. The NR composite filled with 5 wt.% alkali-treated CHp exhibits the highest tensile strength of 7.5 MPa and modulus at 300% elongation (M300) of 2.6 MPa. When the filler content exceeds 5 wt.%, filler agglomeration increases, which negatively impacts the tensile properties of the composite. This work demonstrates that NR composites with cellulose/natural latex masterbatch are effective as reinforcing fillers for natural rubber, enhancing its mechanical performance.
