    The open hole tensile (OHT) test determines the force required to tear a fibre-reinforced polymer composite laminate specimen with a hole located in the centre. In this study, continuous kenaf/epoxy composite laminates with 0o, 15o, 30o, 45o, 60o, 75o, and 90o fibre orientations were modelled and simulated via ANSYS software. The effect of the open hole on the tensile properties of kenaf/epoxy composite laminates was investigated. It was found that kenaf/epoxy composite laminate with 0o fibre orientation, [0]8, exhibits the highest tensile stress in presence of an open hole with a reduction percentage of 17% when compared to the composite laminates without a hole. Meanwhile, Kenaf/epoxy composite laminate with 90o fibre orientation, [90]8, showed the lowest tensile stress and the highest reduction percentage up to 68% in the presence of an open hole. The effect of open hole size (6 mm, 8 mm, and 12 mm diameter) on kenaf/epoxy composite laminate with 0o fibre orientation, when subjected to tensile load, was simulated and analysed. It was observed that the maximum tensile stress of kenaf/epoxy composite laminates reduces with the increase of open hole size. Research on the effect of open holes is important to predict damage resistance and tolerance of composite systems when flaws, damaged areas or drill holes are present.
