摘要:The paper deals with modelling of rheological behavior of composite materials reinforced with fabric from used tires. By this method was analyzed the melt flow rate (MFR) and melt volume rate (MVR) for composite material with 10% fabrics by modeling of rheology system,using statistics concepts and language. The matrix of composite material is thermoplastic,namely polyvinyl butyral (PVB),which is a component in safety car glass. The results help for determination of the quality testing of materials and quality of the manufacturing processes used in engineering industry.
