| Abstract: | The equations for heat transfer and the resin cure dynamics during pultrusion are analyzed through numerical method and find that the temperature and degree of cure in the pultrusion die are strongly coupled together. A computer simulation code based on finite element package IFEPG and FORTRAN has been developed. The computer program is then used to predict the distribution of temperature and degree of cure. The effects of pulling speed on the distribution of degree of cure and temperature in the die are emphatically discussed. |
