Abstract

Journal of Reinforced Plastics and Composites, Ahead of Print.
The influence of fused deposition modeling (FDM) process parameters on the Charpy impact strength of short carbon fiber-reinforced nylon (PAHT-CF) was investigated using machine learning (ML). A total of 129 specimens were fabricated by varying five key ...
