Abstract

Injection pultrusion is an efficient and highly automated continuous process for high-quality, low-cost, high-volume manufacturing of composites. The main objective of this study is to analyze "attached die configuration" and "detached die configuration" for the better injection pultrusion process. In this work the impact of various processing parameters on complete wet out of composite parts is investigated in the attached die and detached die injection pultrusion with various chamber length considerations. The various processing parameters considered are pull speed, fiber volume fraction, resin viscosity, injection port location and compression ratio. 3-D finite volume technique is used to simulate the liquid resin flow through the fiber reinforcement in the injection pultrusion process. The purpose of the present work is to investigate the resin injection pressure needed to achieve complete wet-out, the corresponding maximum pressure inside the resin injection chamber and to predict the resin flow front by varying the length of injection chamber for different processing parameters.
