Journal of Applied Sciences1812-56541812-5662Asian Network for Scientific Information10.3923/jas.2013.1461.1466MaChih-Min WangTao-Hsing YuCheng-Tao ChengBor-Wen 92013139Fiber-reinforced thermoplastics have been gaining popularity for many of the weight critical components in the aerospace and automotive industries. They offer the potential advantage because they are molded in mass-production more easily than are reinforced thermosets. In this study, the main purpose is focused on the two-dimensional stamp forming process for the manufacturing of carbon fiber reinforced polyamide-6. Two different mold angles (90°, 120°) are discussed. The experiments are conducted based on five factors (two levels each) split-plot design with Taguchi L16 orthogonal array. The processing conditions, e.g., the thermoforming temperature, mold temperature, pressure and time, required to give high-quality parts are established. By the results of the analysis of variance (ANOVA), this study derives the best set of the parameters and their estimated equations under different mold angle, respectively. The results have described the correlations between processing parameters and shear stress. Furthermore, for verifying the prediction ability of the estimated equations, the confirmation experiments are conducted. The confirmatory test results, 48.67 and 48.16 kg mm-2, fall in their confidence interval, respectively. It shows that both of the prediction ability of estimated equation and the repetition of the experimental results have confirmed and accepted by the tests.]]>ASTM,20062006Boisse, P., N. Hamila, E.
