Abstract

Although areca fibers have been used by several authors, the Nigerian variety has not yet been thoroughly characterized. In this research the surface of areca fibers was modified by treatment with NaOH or NaOCl2solutions. Lignin content and density of fibers are reduced with the chemical treatment and the NaOCl2treatment causes a significant reduction in moisture absorption. Tensile tests of NaOH (0.25, 0.5, 1, 2, 5, and 10% w/w) and NaOCl2 (1, 2, and 3% w/w) treated fibers were carried out and a reinforcement effect of the areca treated with 2% solutions was observed. TGA measurements showed that with the NaOH treatment the fiber becomes more thermally resistant. SEM micrographs and crystallinity index of areca indicated how different treatments alter the fiber surface. Pull-out tests in polyester resin were performed, evidencing that all treatments were effective in improving interfacial adhesion. The best results were obtained with the 2% NaOCl2treatment. The main advantages of pull-out tests is that without considering composite processing variables, good performance areca/polyester composites may be selected before their laborious and material-consuming preparation begins.
