The purpose of this study is to develop a green composite with high strength and stiffness, using long bamboo fibers, in order to apply biomass resources for practical use. A biodegradable resin was used as a matrix of the composite, and hot-pressed with 60 to 70vol% bamboo fibers. Then, bamboo fibers were dyed to create a good interfacial bonding between the fiber and matrix, and compared with untreated fiber reinforcement. The composites reinforced with dyed bamboo fibers indicate a relatively large tensile strength, similarly to ramie fiber and Manila hemp fiber reinforced green composites, reported elsewhere. In addition, commercially available micro fibrillated celluloses (MFC), nano-sized natural fibers, were added into the matrix to make a better interface, and the green composites were fabricated in the same way. In this study, furthermore, the effect of the interfacial shear strength on the composite strength was explored through a strength reliability model.
