Enhancing the Fatigue Property of Nylon 6 by Using Glass-Fiber Reinforcement and Injection Molding

Abstract:

In this study, Nylon 6 (PA6) was reinforced with glass fibers and molded using different injection parameters. The PA6 samples were then subjected to fatigue tests, and the results were processed to study (i) how the glass fibers affected the PA6 fatigue displacement and (ii) which injection parameters influenced the PA6 fatigue property. To do so, single-factor experimental designs were implemented in which the control factors were the glass-fiber percentage, the melt temperature, the hold pressure, the hold time, the injection pressure, and the injection time. Correlational analyses were used to predict the relationships between the control factors and fatigue results. A two-factor design was then applied to determine the two factors that influenced the PA6 fatigue displacement the most, with analysis of variance being used to determine how the factors affected the fatigue property. In this study of injection plastic, the glass-fiber percentage of PA6 composite was found to be the main factor that affected the fatigue displacement the most.
