Based on optimal scarf joint angle,the authors conducted a series of experiments to evaluate scarf joint angle and pressure on mechanical properties of jointed bamboo.Results showed that:1)the highest tensile strength of the jointed bamboo was achieved with polyurethane adhesive under room conditions and 1.2MPa joint pressure;2)The tensile strength and bending strength of scarf jointed bamboo at an angle of 3.81°were higher than those at an angle of 5.71°and finger jointed bamboo.
