摘要

The hybridization of natural fiber composites is increasing to enhance material performance through the synergistic effects of several fibers. The addition of filler materials has significantly improved the wear resistance of hybrid composites. This study examines the mechanical and wear properties of a unique hybrid composite reinforced with 6 wt% of Peepal fibers, and differnt weight percentages of Okra and Madar fibers. The fabricated specimens were assessed using mechanical characterizations including hardness, impact resistance, flexural strength, interlaminar shear strength, and tensile strength. Different weight percentages (2, 4, 6 and 8wt%) of Titanium Dioxide (TiO₂) nano powder were included as a filler material to enhance the tribological performance. The mechanical properties of the filler-free composite samples comprising 15wt% Okra and 15wt% Madar fibers were superior to those of the other samples. Moreover, among all the configurations analyzed, the sample augmented with 6 wt% TiO₂ filler exhibited the lower wear rate, indicating a significant enhancement in wear resistance. This study emphasizes the potential of TiO2 reinforced hybrid natural fiber composites for advanced structural and abrasion-resistant applications.
