The purpose of this study was to determine the behavior of the bonding ability of coconut fiber against polyester matrix with chemical treatment. First treatments, coconut fiber was soaked into NaOH solution, the second into KMnO4 solution and the third into H2O2 solution, each at various concentration for 3 hours. Between each treatment, the fibre was dried at temperature of 90C for 5 hours. The ability of fiber and matrix adhesion was tested with embed of a single fiber as deep as 2 mm. The results show that the chemical treatment causes the fiber surface becomes rough, forming pores or grooves. The highest average interfacial shear stress is obtained in the H2 treatment, because of the rough fiber surface and small grooveds so that when the fibers were implanted into the matrix, the matrix has a strong grip resulting in a good bonding between the fibers with the matrix. While the fiber highest average tensile stress was obtained in N4 treatment, because fiber was draped by small crystals which are unified so that it increase the ability of the fiber receives a tensile load and slow fiber rupture.
