Abstract
It is very important to understand a dynamic fracture behavior under the high temperature environment. However, these researches of polymeric materials is unexpectedly little. In this study, the cracked polycarbonate plate was used for a sample material, and carry out the impact three point bending test in the electric furnace. The caustics method and the simple high-speed photography method was used for the analysis. As experimental results. A different fracture behavior was shown whether by doing the dehydration processing same normal temperature (23.5 degrees Celsius). At the higher temperature, the dynamic stress intensity factor indicated lower value. In addition, it has been understood that there is a tendency to which the fracture toughness value decreases while becoming a high temperature.
