For the real time characterization of pultrusion processes with a complex temperature control, two finite-element modeling approaches utilizing a continuous model with lumped material properties for a cured composite have been developed. The first procedure, based on the mixed time integration scheme and the nodal control volumes method, is working in the ANSYS Mechanical environment, but the second procedure is performed using the ANSYS CFX software with the cure reaction introduced as an additional variable. New cure sensors measuring the temperature and electrical resistivity of resins have been developed for the inline process control. To demonstrate the accuracy and reliability of the numerical procedures and new sensors, two technological processes with a temperature control examining the pultrusion of I-beam and rod profiles have successfully been analyzed.
