AbstractIn this study, thermoplastic composite (AS4/APC-2) rings were fabricated using automated fiber placement technique. To compare the quality of the rings under different process conditions, differential scanning calorimetry (DSC) test was conducted to investigate the crystallinity level in the samples. Short-beam shear test was performed to demine the interlaminar shear strength. Digital Image Correlation (DIC) technique was used to measure ultimate through-the-thickness strain. Microscopic photos were used to determine the failure mode. Based on the short-beam strength results, Taguchi method was employed to identify the significance of each process parameters and to obtain the optimum process conditions.
