Abstract: DOI: 10.24193/subbphys.2019.05 Published Online: 2019-12-30 Published Print: 2019-12-30 pp. 41-53 VIEW PDF FULL PDF Paper and paperboard have many applications, from writing, printing and householding to packaging. Bending stiffness is probably the most important mechanical property of paper and paperboard, it provides rigidity in some industrial processes like printing or folding. The present work describes the design and implementation of a low-cost bending stiffness tester proposed as a graduation project for Engineering Physics students. The performances of the device were successfully tested on both certified and real-life paper products. Key words: bending stiffness, paper products, strain gauge, load cell, stiffness tester |
