Resumen:
In this work a Population Balance Equation (PBE) model is used to predict the evolution of the fiber breakage in thermoplastic-polymer/short-fiber composites during capillary extrusion. The least squares spectral method was used to solve the resulting integro-differential equation. The differences found between the experimental and simulated data were attributed to the selected breakage rate and redistribution functions. An experimental setup is proposed to find accurate breakage functions for this problem. The application of the PBE for such a breakage process could be a powerful tool for the design of injection moulding moulds.
