Abstract
This study deals with the measurement of the deformation of sheets of recycled paper subjected to tensile loads using an electronic speckle pattern interferometry (ESPI) technique. Specimens with fibers, which constitute a sheet of paper, parallel and perpendicular to the direction of paper making are used to investigate the effect of the arrangement of fibers on the tensile property. The deformation of recycled paper is compared with that of virgin pulp paper. Results reveal that a large two-dimensional deformation of recycled paper can be measured using the ESPI technique, and that the directions of fibers, which constitute a sheet of paper, have a significant effect on the two-dimensional deformation of recycled paper.
