From the former research, the formula about two overlapped paper books with no modification was induced from mathematical analysis. The main purpose of this research is to test the friction force and friction coefficient of modified paper books and suggest analysis about that. Modifications that were used in this research are holes and scratches. The result shows that papers with holes and scratches affect the fric tion force of the paper. With this research, it was found out that paper with many holes, smaller holes and holes with longer perimeter has higher friction force. It was also found out that paper with shorter gap between scratches has higher friction force and the angle of scratches does not matter with the frictionforce of paper. The reason afforce increase is the cut fibers of paper which functions like hooks. These hook-fu nctioning fibers hook paper fiber and cause increase of friction force.
