Abstract

This paper presents a numerical model for predicting pressure, IMPREGNATION and PULLING FORCE in PULTRUSION die with circular cross section which has two reinforcement fibrous tows that pass through it.Pulling force and degree of IMPREGNATION are the most important parameters associated with PULTRUSION process that determine production cost and quality of pultruded profile respectively. The main idea in this approach is obtaining characteristic equations in purely polymer region and purely fibrous region and establishing relations between them by using conservation law. The superiority of this approach compared to other methods is the ability to consider both the straight and the conical part of the die, calculating PULLING FORCE, ability of investigating influence of a variety of parameters such as those associated with die geometry, material rheology and process parameters. In this paper the influence of fibers position and fibers radius on PULLING FORCE, IMPREGNATION and pressure inside die is investigated.Due to the ability of simultaneous calculation of force and IMPREGNATION, this model can be used to establish an optimum condition between cost and quality of produced profiles.
