The Effect of Process Parameters on Impregnation Properties of Pultruded Carbon Fiber Reinforced Thermoplastic Epoxy Composites

Abstract

During the pultrusion process, there are some parameters that effect the impregnation performance of pultruded composites. The pultruded carbon fiber reinforced thermoplastic epoxy composites processing parameter such as pulling speed, resin viscosity, molding temperature of the pultruded composites that have to be considered and pulling speed one of parameter is discussed in this research. In our previous research, it has been clarified that the carbon fiber reinforced thermoplastic resin fiber composites had not been good impregnation and surface for pultrusion process. The main problem during the processing of carbon fiber reinforced thermoplastic resin composites is the impregnation of the fiber reinforcement with highly viscous resin. The objective of this research is to improve an impregnation performance by using the low viscosity of thermoplastic resin. To achieve this objective, thermoplastic epoxy resin were used instead of thermoplastic resin fiber. In this research is to studies an effect of pulling speed on impregnation of carbon fiber reinforced thermoplastic epoxy resin composites by using pultrusion technology to produce the hollow shape composite. The effect of pulling speed were evaluated.
