Nylon 6 clay hybrid (NCH) composite consists of nano-sized Montmorillonite and nylon 6 matrix. Tensile tests at near glass transition temperature (35℃, 50℃) were conducted at a strain rate of 10^<-2>s^<-1>. Fatigue tests were performed with a stress ratio of 0.1 and frequency of 0.1 Hz. Although the tensile strength and fatigue strength of NCH-2 are the highest at room temperature, the tensile strength and fatigue strength of NCH-5 become the highest at 35℃,50℃. Fatigue fracture surfaces show different patterns between at room temperature and 35℃,50℃. Fatigue fracture surfaces show that fatigue fracture of NCH-2 is brittle at room temperature, but ductile at 35°C,50°C, while fatigue fracture of NCH-5 is brittle at both room temperature and 35℃,50℃.
