ABSTRACT

This paper discusses the development, implementation and application of numerical schemes for modelling the effects of temperature-dependent material properties including chemical shrinkage and thermal expansion of resin on the curing of thermosetting composites in pultrusion. The results of the three-dimensional simulation of heat and mass transfer in pultrusion of regular as well as irregular and hollow sections are presented.
