Acrylic resin plate is expected to be used as a replacement for glass windows of automobile and so on. In such a use, a small particle collides repeatedly to the plate. However, impact fatigue strength of acrylic resin plate isn't evaluating yet. In this paper, evaluation method of impact strength of acrylic resin plate was suggested. The resin plate thickness of 2mm, 3mm and 5mm were used in this study. Rectangular specimens were made from the resin plate. Two test equipment are used in this study. One of test equipment is based on the principle of free fall and another equipment emits steel balls in high speed. A weight collides to the specimen that is supporting simply both ends. A kinematic energy calculated from the collision velocity and mass of the weight were recorded. As a result, it is necessary to consider the rate dependence for the evaluation of the impact strength of acrylic resin plate was founded.
