Pineapple leaf fibre (PALF) is a waste product of pineapple cultivation. This fibre has potential as reinforcing fillers in thermosets, thermoplastics, and elastomers and exhibit excellent mechanical properties. However, PALF reinforced natural rubber has not been reported in literature. Therefore, the mechanical properties of pineapple leaf fibre (PALF) reinforced rubber composite have been studied. The objectives in this study were to investigate the effect of fibre loading, addition of coupling agent and fibre treatment in rubber composite by comparing the mechanical properties. PALF and rubber were compounded in two roll mill machine and hot press to form composite sheet. Sodium Hydroxide (NaOH) was used as treatment agent and Vinyl trimethoxysilane (VTMO) as a coupling agent. The mechanical properties were analyzed by standard testing namely Tensile Test (ASTM D412) and Hardness Test (ASTM D2240). Tensile and hardness properties basically show improvement. Tensile strength decreased with increasing fibre loading. Meanwhile, hardness and the YoungÂ’s modulus are increased with increasing fibre loading. Moreover, by the addition of coupling agent, tensile strength and hardness were improved. The results also showed that rubber composite filled with treated fibre had higher tensile strength and hardness than untreated fibre at similar loading.
