Integral assessment of cardboard properties for stiffeners

The aim of the research is to assess and analyze the physical and mechanical properties of cardboards for stiffeners, as well as to develop an integral quality indicator that allows determining the best sample of materials. The object of research is modern leather cartons used for the production of stiffeners. The subject of research is their physical and mechanical properties. The article describes a set of indicators selected to evaluate the physical and mechanical properties of cardboard for stiffeners. Their characteristics and methods of assessment are given, the obtained data are presented. The results of assessing the quality of materials for stiffeners as a complex of their property indicators are discussed. The method used is an integral quality assessment method. As the result of the work the best article of cardboard for using in the production stiffeners is determined. The application area of the results is the footwear industry.
