Moisture Dependence of Impact Rupture Properties of Paper

Abstract

There are a number of studies on the relationship between the mechanical properties of paper and adsorbed water. In other previous papers-Anderson⁽¹⁾, Yoshino⁽²⁾, and Kadoya⁽³⁾ which concerned moisture dependence of mechanical properties of paper under impact conditions, it was found that the maximum values in the impulse or rupture energy existed at 15-18 per cent moisture content. The reason why such a maximum value exists is, however, left unsolved, because of the complexity of failure mechanism under impact conditions.
