This research aims to study the influence of surface modification on tensile strength of single sisal fibre. It is to compare between 2 groups of fibres: one with surface modification and one without. The fibres were immersed in 1 M concentration of NaOH solution at 60oC by ultrasonic process for 30, 60, and 90 min respectively. The tensile strength of single sisal fibre was conducted by fibre testing Instrument according to ASTM D2256-02 Standard. From experimental results, it is found that the treated fibre had cleaner surface than the untreated fibre. Compared to the untreated fibre treated fibre also had higher tensile strength and percent elongation. However, the tensile strength would be decreased if the fibres were immersed longer in the solution.
