Improving of the Properties of Carbon Fiber Reinforced Semi-aromatic Polyamides Molded Products with Injection Mold Capable of Both Melt Flow Control and Induction Heating

Abstract

In previous study, we developed an injection mold capable of both melt flow control and induction heating, and has demonstrated that the mold is able to prevent weld lines and reduce the deterioration of the appearance and strength of molded products. In this paper, we applied this mold to the forming of short carbon fiber reinforced semi-aromatic polyamide molded products and evaluated how the heating and cooling of the mold and melt flow control, as well as gas vent affects the appearance and mechanical properties of molded products.
