Abstract
Objective: A comparative study was carried out to determine the reinforcement efficiency of palm fruit fibre (PFF) and coconut fibre (CNF) in high-density polyethylene (HDPE) composites.
Method: For both fibres the physical properties such as bulk density, pH, and particle size were first assessed. Then mechanical tests such tensile strength and impact strength were also carried out.
Results: PFF had higher bulk density (99.20 kg/m³) and pH (9.00), while CNF had greater particle size (6.10 kJ/m²) and moisture content (5.32%). Mechanical testing revealed that PFF significantly enhanced tensile strength (up to 22.56 N/m²) and impact strength (1.26 kJ/m²) at 10–20 g loading, but reduced abrasion resistance and elongation at break. CNF also improved tensile (21.88 N/m²) and impact strength (1.01 kJ/m²) at 10 g, but caused greater reductions in abrasion resistance and a more substantial increase in water absorption, reaching 43.01% at 20 g. Solvent absorption tests showed a general increase in kerosene, petrol, and diesel uptake with higher fibre content for both composites. PFF composites showed the highest petrol absorption (25.12%) at 20 g, while CNF composites exhibited greater overall solvent and water uptake. The findings indicate that PFF offers better mechanical reinforcement, while CNF shows higher fluid affinity.
Conclusion: The choice between fibres should therefore depend on whether mechanical performance or resistance to moisture and solvents is prioritized in the intended application.
