Abstract

Using the combination compression shear fixture by improving,shear load-displacement data of transverse and longitudinal sample for corrugated composite paperboard( CCP) and honeycomb paperboard with the different thickness were tested and the corresponding shear strength histogram were also drawn. The results showed that: Shear resistance of longitudinal sample is greater than that of transverse sample for the sandwich structure paperboard; Under the same liner and medium,shear resistance with the same direction for the CCP and honeycomb paperboard decreases with increasing paperboard thickness,but the shear resistance of honeycomb paperboard with the same thickness and direction is larger than that of the CCP,so the entirety shear resistance of honeycomb paperboard is better than that of the CCP. The results provide the basis of compression shear for the further application of sandwich structure paperboard.
