Impact of Single and Multiple Injection Slot Locations for Attached-Die and Detached-Die Tapered Resin Injection Pultrusion

This study compares the performances of the detached-die with the attached-die resin injection chamber configurations for pultrusion manufacturing. The impact of geometric design parameters (axial location of single injection slot and axial location of multiple injection slots) on the performances and complete reinforcement wetout for both the attached-die and detached-die configurations are investigated for various chamber lengths and compression ratios. Feasible manufacturing solutions are determined from the results.
