A study has been conducted to calculate theoretically the impact fracture strength of Japanese paper on the basis of the orientation of its constituent fiber. The impact strength of paper is known to be defined as the energy which can be aborbed in the paper until its rupture during impact loading. The theoretical analyses have shown that the impact strength of Japanese paper is dependent upon the cut direction of specimen sheet; the magnitude of impact strength is the greatest in the cross direction of paper which is normal to the machine direction and decreases gradually with deviating from the cross direction of paper, while the minimum is seen in the range of the cut direction of 50 to 60 degrees. The theoretical predictions were supported by the results of experimental measurements of Haku-Uchi Gami (Japanese paper).
