Abstract: Thermosetting-matrix composites have become attractive in aerospace industry on account of their numerous advantages over conventional materials, such as their intriguing physical and mechanical properties, and their designable ability in terms of the design process and the subsequent manufacturing process. Despite these benefits, process-induced distortion is crucial issue since it cause assembly difficulties and residual stresses. This paper aimed at reporting the current research status of the process-induced distortion behavior of thermosetting-matrix composites, which was introduced during the hot forming process. The process-induced distortion mechanism, the related numerical simulation method, artificial neural network method and its application in the process-induced distortion were mainly introduced. An emphasis being placed on the state-of-art development of high-throughput prediction and inverse design of process-induced distortions based on artificial neural network. Finally, the future development directions of process-induced distortion and artificial neural network were briefly discussed.
