This paper aims to develop and demonstrate a simple lab-scale vacuum-assisted resin transfer molding (VARTM) technique to fabricate a hybrid natural fibre-reinforced composite with reinforcement from fibres and particulate forms. A study was conducted to investigate the effect of different filler sizes on the mechanical properties of the natural hybrid reinforced composite and showcase the effectiveness of the hybrid composite fabrication using the VARTM technique. The primary phase of the composites was epoxy resin, with reinforcement of oil palm empty fruit bunch (OPEFB) fibres and oil palm kernel shell (OPS) particulates embedded into the resin as the secondary phase of the composites. The results indicate that incorporating smaller-sized Oil Palm Shell (OPS) particulates (≤75 µm) enhances the compressive properties of the hybrid composite. In contrast, larger particulates (150–300 µm) did not pass through intra-fibre spacing due to permeability issues, resulting in weaker bonding and reduced compressive strength.

摘要

This paper aims to develop and demonstrate a simple lab-scale vacuum-assisted resin transfer molding (VARTM) technique to fabricate a hybrid natural fibre-reinforced composite with reinforcement from fibres and particulate forms. A study was conducted to investigate the effect of different filler sizes on the mechanical properties of the natural hybrid reinforced composite and showcase the effectiveness of the hybrid composite fabrication using the VARTM technique. The primary phase of the composites was epoxy resin, with reinforcement of oil palm empty fruit bunch (OPEFB) fibres and oil palm kernel shell (OPS) particulates embedded into the resin as the secondary phase of the composites. The results indicate that incorporating smaller-sized Oil Palm Shell (OPS) particulates (≤75 µm) enhances the compressive properties of the hybrid composite. In contrast, larger particulates (150–300 µm) did not pass through intra-fibre spacing due to permeability issues, resulting in weaker bonding and reduced compressive strength.
