In this study, wood-pulp／bio-based poly (butylene succinate) (Bio-PBS) laminated composites were made by using papermaking techniques. Wood-pulp fibers were treated with 3-aminopropyltrimethoxysilane (APTMS) and poly (vinyl alcohol) (PVA) to improve the interfacial adhesion between the wood-pulp fibers and Bio-PBS. Wood-pulp fibers without being processed (PF), wood-pulp fibers treated by APTMS (PF-Si), and wood-pulp fibers treated by both APTMS and PVA (PF-Si/PVA) were converted to sheets by the papermaking technique. Those sheets and Bio-PBS films were used to make wood-pulp/Bio-PBS laminated composites by hotpressing and cut into test pieces. Tensile testing and the heat distortion temperature measurements were conducted with those samples. As a result, the tensile strength of composites was close in value to that expected by the Reuss model when the volume fraction of wood-pulp was 12％ and 24％. Furthermore, the tensile strength of composites containing PF-Si/PVA was higher than that of composites containing PF and PF-Si. The heat distortion temperature of the composites was higher than that of Bio-PBS, although the effects of surface treatment on the heat distortion temperature were not confirmed. Microscopy observations of composite fractures indicated that the surface treatment of wood-pulp fibers enhanced interfacial adhesion between the woodpulp fibers and Bio-PBS.
