| Popis: | 96 This study investigates the influence of injection molding process parameters on the tensile properties, wear properties and impact toughness of 15wt.% Glass Fiber Reinforced Polyoxymethylene (POM/15wt.%GF). The author combined the Taguchi experimental design, analysis of variance (ANOVA) and artificial neural network to optimize the manufacturing process. Then, the Taguchi experimental design, principal component analysis (PCA) and Artificial Neural Network were utilized to evaluate a comprehensive index for multi-response cases. The results of Taguchi experiment design and ANOVA showed that the optimum manufacturing parameters was filling time 1.5 s, melting temperature 200℃, mold temperature 60℃ and packing pressure 55 MPa for tensile properties. Melting temperature was the most significant parameter among them. When we consider the multi-response of tensile strength, friction coefficient and impact absorb energy, the analytical results of Taguchi experiment design and PCA showed that the optimum manufacturing parameters was filling time 1 s, melting temperature 200℃,mold temperature 75℃ and packing pressure 55 MPa. Also, melting temperature was the most significant parameter. |
