The mechanical property of cellulose acetate in the range of room temperature is affected remarkably by the strain rate and temperature. In this paper, the effect of strain rate and temperature on the breaking strength and the fracture surface of notched cellulose acetate plates are examined. As a result, the breaking strength of notched cellulose acetate plates increased with increased strain rate and decreased with increased temperature. The breaking strength is approximated by the power law incorporating the strain rate and the temperature. The equation proposed gives a good agreement with the experimental results, so the breaking strength of notched cellulose acetate plates could be predicted. The observation of the fracture surface shows the fact that the fracture surface is influenced by the strain rate but not by the temperature.
