Impact and Tensile Properties of Injection-Molded Glass Fiber Reinforced Polyamide 6 –Processing Temperature and Pressure Optimization

Abstract

Polyamide 6-short glass fiber composite is one of the advanced materials used for lightweight-high strength applications. To some extent, the mechanical properties of the composite depend on its manufacturing process. The most common method to produce thermoplastic polymer products is injection molding. Production of injection-molded components may use process parameters that can vary significantly since it is a variable that depends on the type of polymer materials. This study intends to find the relationship between tensile strength and impact strength of short glass fiber reinforced polyamide-6 composite with the injection molding process parameters, namely barrel temperature, holding pressure, and injection pressure. The Taguchi method was used for the analysis. The result shows that barrel temperature is the most influencing parameter for tensile strength and impact strength.
