In this research, a laminate material (a phenolic resin reinforced by plain woven cotton cloth) was used for the gear material. The gear was produced by hobbing. In this paper, we addressed the bending strength of gear teeth in the basic design process. First, Vibration characteristics between metal gear and metal gear and cotton fiber-reinforced plastic gear and metal gear when the gears meshed are compared. Second, bending fractures in teeth, were examined by a line load applied to the tooth root fillet and tooth breakage in this area during bending was investigated. Third, to investigate the repetition fatigue strength of teeth, a fatigue test was performed. Forth, tension, uniaxial compression, 3-point and 4-point bending, and shearing tests were performed for the gear materials used in order to investigate the destruction strength of the gear shape and the primary factors in the destruction form.
