The purpose of this study is to determine the effect of turmeric solution (Curcuma) on the fiber sheath Akaa (Corypha) toward the interfacial shear stress (IFSS) and wettability on epoxy resin matrix. The first treatment of Akaa fiber sheath is soaked in distilled water. The second treatment is fiber boiled in a turmeric solution for 1 hour. The third treatment isboiled in the turmeric solution for 2 hours and the fourth treatment is boiling the fiber in a turmeric solution for 3 hours. The boiling temperature is 100 C and under a pressure of 1 atmosphere. Each fiber sheath Akaa after treatment, was dried at room temperature for about 48 hours. The solution used is 20% of turmeric powder and 80% distilled water under a unit volume.The matrix material is a thermoset epoxy. A tensile testing was done to obtain the specimen shear stress based on the ASTM 3309-02 rule and wettability rule. Furthermore a SEM and Energy Dispersive X-Ray Spectroscope (EDS) test was done to get the fiber composition and fiber chemical composition. The hydrolysis test and Fourier Transform Infrared Spectroscopy test (FTIR) was done to determine the hemicellulose composition, cellulose composition, lignin composition.From the results showed that the turmeric treatment would affect the single fiber interfacial shear stress and single fiber wettability. The highest shear stress is 29.48 N/mm2 in fibers treated for 1 hour boiled in turmeric solution. © Research India Publications.
