Abstract

In the present study, numerical modelling has been used to assess the influence of non-uniform fibre distribution on the temperature and degree of cure field in Resin Injection Pultrusion. The fibre distribution of an industrial glass-fibre/polyutherene profile with a square cross-section was investigated using the burn-out process and light optical microscopy. Both characterization techniques showed non-uniform fibre distributions. The characterized fibre distribution trends were implemented in a numerical model and compared with the corresponding uniform case. The results show a significant change in the cure behavior from solely outside-in curing in case with a uniform fibre distribution to inside-out curing for the center part of the profiles with non-uniform fibre distribution.
