| Summary: | In recent years, the demand for environmental friendly materials based on biodegradable polymer and natural fiber has growth interest. In this work, oil palm empty fruit bunch (palm fiber) reinforced polylactic acid composites in sandwich form were processed by compression moulding. However there were several limitations especially related to the fiber-matrix adhesion. So the OPEFB fibers were treated by ã- aminopropyl trimethoxysilane (APS) or methyl trimethoxysilane (MS) and coated by polylactic acid (PLA) in varied percentage (5%, 10% and 15%). The effect of APS, MS and PLA coating on the flexural and dynamic mechanical properties of palm fiber/PLA composites was examined. The flexural properties of composites were found to increase with increasing fiber coating and improved by introduction of APS. It was also observed that the APS, MS treated fibers and PLA coating fibers have improved the dynamic mechanical properties of the composites respectively. |
