In-line characterization of pultruded profiles

For in-line characterization of pultruded profiles, two alternative ANSYS based finite element modelling approaches using the same continuous model with lumped material properties for the cured composite are developed, compared and discussed. The first procedure is developed in ANSYS Mechanical environment and based on the mixed time integration scheme and nodal control volumes method. The second procedure is performed by using ANSYS CFX software with the cure reaction introduced as an additional variable. Validation of the developed algorithms is realized by the analysis of pultrusion process for the rod profile controlled in-line by new cure sensors measuring the temperature and electrical resistivity of the resin on the profile surface.For in-line characterization of pultruded profiles, two alternative ANSYS based finite element modelling approaches using the same continuous model with lumped material properties for the cured composite are developed, compared and discussed.
