ABSTRACT
Injection pultrusion is a continuous process of manufacturing composites with a constant cross-section by pulling a fibre matrix through a resin injection chamber and into a heated die where the resin is subsequently cured. The objective of the present study is to obtain a quality composite by achieving complete resin wet-out of the fibre reinforcement. Complete wet-out depends on processing parameters and design parameters. This work deals with the impact of two design parameters (injection slot width and composite part thickness) on the minimum resin injection pressure required to achieve complete wet-out along with the associated chamber interior pressure for various resin injection chamber lengths with different tapering angles.
