abstractThe object of the study is fiber-filled polymer composite materials made of secondary polyurethanes and dispersed woodworking waste. The subject of the study is the physical and mechanical properties of fiber-filled composite materials. The aim of the study is to determine the influence of the percentage of investment and morphology of wood waste on the physical and mechanical properties of fiber-filled polymer composite materials for the shoe bottom parts. The article studies the parameters of the woodfiber mass used to create fiber-filled composite materials. Polymer composite materials of the leatherette type with a filler content of 0–5.0 wt% were produced, their physical and mechanical properties were investigated. The practical value of the research results consists in producing materials with a certain set of properties that meet the requirements of regulatory documents and are within the framework of traditionally used shoe bottom materials, as well as in establishing prescription and technological capabilities to overcome the factor of natural deterioration of the properties of secondary shoe polyurethane foams by modifying wood-fiber waste. Results of the work are materials of the leatherette type made on the basis of shoe polyurethane foam waste and their physical and investigation of their mechanical properties. Wood fillers in the form of fibrous particles can be considered as inexpensive additives to polyurethane matrices, which, under certain compounding and technological parameters of the composite formation, enable to compensate to some extent for the deterioration of the physical and mechanical characteristics of the recycled PРU. The field of application of the results is the shoe industry. Properties of Fiber-Filled Polymer Composite Materials of Leatherette Type |
