説明

The present study has been made to inquire experimentally into the effect of testing conditions, such as the gripping pressure on the specimen, the size of the specimen and the weight of the ball, upon the impact resistance of some plastics in the experiment worked by the falling ball method.<br>The results obtained are as follows;<br>(1) The gripping pressure has the greatest influence on the impact resistance, and the greater the pressure is, the less the impact resistance is.<br>(2) The impact resistance increases with the increment of its supporting distance and the thickness of the specimen, but generally it does not increase with the increment of the breadth of the specimen.<br>(3) The required falling height H to break the specimen is lowered by the increment of the weight W or the size of the falling ball, but the energy WH to break the specimen is little affected by that.
