Injection pultrusion is an efficient process for manufacturing composites of continuous lengths with constant cross-section area. The main objective of this study is to compare the performances of the detached-die with the attached-die resin injection chamber configurations. In this work the impact of various geometric design parameters (the length of the injection chamber, slot width, multiple injection slot locations, and part thickness) on the performances and complete wetout of the composite parts for both the attached-die and detached-die configurations is investigated with various chamber lengths and compression ratios. A 3-D finite volume technique is employed to simulate the liquid resin flow through the fiber reinforcement and to predict the liquid resin flow front. A minimum injection pressure for a complete wetout of the composite parts in both the attached-die and detached-die configuration is determined along with the associated maximum interior chamber wall pressure. Feasible manufacturing solutions are determined from the results. The detached-die resin injection configuration was always better than attached-die configuration. Shorter injection chamber lengths at higher compression ratios were found to yield better performance and more feasible manufacturing solutions.
