Due to the increasing demand, carbon fiber reinforced plastics (CFRP) have become more and more important in many fields. In this study, a hybrid incremental sheet-forming technique for carbon fiber reinforced thermosets (CFRTS) was developed and applied. In this technique, a layer of CFRP sheet was placed under another layer of mild steel sheet called the dummy sheet. Various experiments were conducted, and the results show that this forming strategy can be applied to CFRP sheets having single-or multi-layer prepregs. In addition, the mesoscale model simulation using ABAQUS/Explicit was performed for the incremental sheet forming (ISF) process of the CFRP sheet, and the effect of orientation of fiber on the forming process was discussed. The FE simulation results for the ISF of the CFRP sheet was able to predict the deformation shape and shear angle of the CFRP sheet accurately compared to the experiment.

由于需求的增长，碳纤维增强塑料（CFRP）在许多领域变得越来越重要。在这项研究中，碳纤维增强热固性塑料（CFRTS）的混合增量片材成型技术得以开发和应用。在这种技术中，一层CFRP板被放置在另一层称为虚设板的低碳钢板之下。进行了各种实验，结果表明该形成策略可以应用于具有单层或多层预浸料的CFRP片材。此外，针对ABAQUS / Explicit对CFRP片材的增量片材成型（ISF）过程进行了中尺度模型仿真，并讨论了纤维取向对成型过程的影响。
