Abstract
Pultrusion is one of the most cost-effective processes for composite materials manufacturing. It allows to realize constant section products characterized by remarkable fibres alignment, mechanical properties directionality, good surface quality with high production rate. Thermo-chemical aspects, such as temperature and degree of cure, are very important in order to obtain good mechanical properties of the final product as fast as possible or to realize a post-die shaping of pultruded parts. In this paper a three-dimensional finite difference model based on A.D.I. method and realized in MATLAB language for temperature and degree of cure is proposed. The present model takes in account heat transfer due to heating platens, die-cooler at die entrance and resin exothermic cure reaction. An analysis of the influence of mesh density and Peclet number on model accuracy is presented. Numerical results are compared with experimental data.
