In this research, the aim of the study is to investigate the mechanical properties of eco-hybrid natural polymer of kenaf and glass fibre. The specimens were fabricated using vacuum infusion technique and joining into single lap bolted joint. The mechanical fasteners of Huck lock bolt were used as joining method with the bondline length of 64 mm. The investigation was conducted under two different conditions of dry and wet of 50°C for water immersion of 20 days. The effect of moisture was defined in bolted joints materials. The tensile test with a speed rate of 1 mm/min was conducted for both condition using 100 kN load cell until total failure of specimen. The experimental results were plotted into load displacement and stress strain curve for each environment.
