초록

The purpose of this study is to improve the interfacial adhesion strength of bamboo/PBS composites by adding HDI (hexamethylene diisocyanate) as a coupling agent. Bamboo/PBS composites with HDI were fabricated by an internal mixer and a hot press machine. In addition, the effects of HDI as a coupling agent and various HDI contents on the mechanical properties of bamboo/PBS composites were investigated. Furthermore, the tensile properties, flexural properties, and Rockwell hardness of bamboo/PBS composites with HDI were evaluated. The obtained results showed that the mechanical properties of bamboo/PBS composites were improved with the addition of HDI. The morphology of fractured surfaces of bamboo/PBS composites was observed with SEM (scanning electron microscope), and the obtained SEM images showed evidence of improved interfacial adhesion between the bamboo fiber and PBS matrix. To analyze the composition change of bamboo/PBS composites, FT-IR (Fourier transform-infra red) spectroscopy was used. The FT-IR spectra of bamboo/PBS composites also showed positive effects of using HDI as a coupling agent. Finally, a comparison of various HDI contents, when all obtained results were combined, showed that bamboo/PBS composites with a HDI content of 1.5% had the most improved mechanical properties.
