Abstract: Palm fiber, as the reinforcement of green biological composites, was soaked in seawater for 1, 2, 3 and 4 weeks before use. Natural sago starch was used as matrix compound instead of ordinary resin matrix. It was observed by scanning electron microscope (SEM) that the impregnation treatment significantly affected the surface morphology of the fiber and the interface between the fiber and the matrix. The longer the seawater immersion time, the higher the interfacial bonding quality. After soaking for 4 weeks, the gap between the fiber and the matrix disappeared, indicating that the interface between the fiber and the matrix was the best. In the soaking process, the morphology of fiber surface interlocking process is clearly visible.
