Abstract

In this paper, oil palm fiber (OPF) and pineapple fiber (PALF) reinforced biophenolic resin (BPHR) composites and hybrid composites were fabricated by hand lay-up technique. Structural, thermal and mechanical properties of pure and hybrid composites analyzed by Fourier transform infrared (FTIR), thermal gravimetric analyzer (TGA), dynamic mechanical analyzer (DMA), and universal testing machine. Achieved results indicated that OPF/PALF hybrid composites show better properties as compared with pure composites. It was observed that the tensile and flexural characterizations improved with incorporating OPF and PALF fibers into BPHR composites in comparison to the neat BPHR matrix. The results of the thermal stability obtained from TGA tests showed that the reinforcement of pure fiber composites (OPF and PALF) and hybrid composites (OPF/PALF) in BPHR matrix were improved in comparison to that of neat BPHR matrix. The final decomposition temperature of 50% OPF and 3OPF/7PALF was the highest among all other composites (415.80 and 415.42°C). On the other hand, the residual amount of hybrid composite (1OPF/1PALF) was (24.43%), while the lowest residual amount exhibited in pure composite (50% PALF), which was 20.08%. The reinforcement of pure composite and hybrid composites into BPHR also improved the storage and loss moduli; however, the pure composite sample (50% OPF) exhibited a more significant increase than other composites loadings. Furthermore, the damping factor was reduced significantly by the reinforcement of hybrid composites over pure composites. This study showed that obtained hybrid composites are suitable to apply in various structural and nonstructural applications.
