In this study, a series of bamboo plastic composites were prepared by extrusion and molding, in which polypropylene (PP) was used as the matrix and Phyllostachys pubescens fibers as the rein-forcing material. As well as the chemical structures of modified and unmodified bamboo fibers, the micro-morphology of bamboo fibers and composite brittle sections were investigated. Two kinds of materials, i.e., composites with different bamboo powder contents and containing coupling agent account for 2% of bamboo powder content, and plastic composites with 5 wt% bamboo powder and different coupling agent...
