Fiber reinforced thermo-plastic composite materials offer significant potential advantages comparing thermo-set composites, including higher damage tolerance, unlimited shelf life, faster component manufacturing times, greater recyclability and improved work environment. However, it is generally difficult to properly impregnate fiber reinforcements during the manufacturing process, because of extreme high viscosity of the thermo-plastic matrix materials compared to that of thermo-set resins. Due to these difficulties in resin impregnation, intermediate materials using Micro-Braiding technique have been developed. In this study, process parameter investigations were carried out to determine the most suitable values of pressure, temperature and time for resin impregnation during molding. Impregnation was evaluated by observing cross-sectional surface. Impregnation ratio increased with molding pressure, time and temperature. Especially, molding pressure was more effective on impregnation. It is confirmed that effect of molding temperature on impregnation was less comparing to that of others.
