Abstract

The purpose of this study was to determine the effect of treatment Alklali (NaOH) on the surface of coconut fiber covering the surface roughness, tensile strength, and the ability of bonding between coconut fiber with polyester matrix.Coconut fiber soaked in a solution of alkali with a concentration of 5%, 10%, 15%, 20%, and then dried in an oven at atemperature of 90 oC for 5 hours. Fiber surface roughness testing is done in two ways namely SEM and surface roughness measuring instrument. Single fiber tensile strength and fiber pull out test was performed with a tensile test. Based on these test results, it was concluded that concentration solution of alkali to give effect to the surface roughness of coconut fiber, increasing the tensile strength, and improve bonding with the fiber and polyester matrix. The alkali treatment increase of the surface roughness of coconut fiber until 3.96 m. In the 20% alkali treatment obtained tensile and shear strength is highest, respectively 280, 94 N/mm2 and 3, 09 N/mm2. Keyword: coconut fiber, chemical treatment, tensile strength, surface roughness.
