Description
Abstract. In this research, the study to investigate and compare the physical and
mechanical properties of water hyacinth and cogon grass fiber reinforced epoxy resin
composites. The composites were fabricated by hand lay-up process. The effect of investigation
was analyzed via water absorption, microstructure, tensile properties, flexural properties and
impact strength tests for total fiber contents, 15 wt% and different water hyacinth- cogon grass
fiber ratios (10/0, 8/2, 6/4, 4/6, 2/8 and 0/10). The results showed that the addition of water
hyacinth and cogon grass fiber in epoxy, improves tensile properties, flexural properties and
impact properties, but decrease water absorption. The analysis of the microstructure found that
surface fracture behavior and void between the fiber and matrix of the composites using
scanning electron microscope (SEM).
