Recently, polymer materials are used in various fields, the expansion of the use is performed more and more now. However, the mechanical characteristic of their materials depends on the use conditions such as the temperature greatly. Therefore, to expand the range of use of polymer materials further, it is necessary to understand various the material characteristics. The purpose of this study is to examine the dynamic fracture characteristic of polymer materials considering temperature environments. Caustics method has been used to determine dynamic stress intensity factor K_I and we evaluated the strength of materials. As a result, with a rise and a fall of the temperature, the maximum value of K_I showed the tendency to decrease in all materials, hi conclusion, it was found that dynamic fracture characteristic was different greatly by a difference of the materials under temperature environments in the polymer materials.
