Abstract

In recent years, innovations in 3D/4D printing techniques for continuous fiber-reinforced polymer composites (CFRPCs) have opened new perspectives for the integrated design and manufacture of composites with customized functions. This paper reviews the current state of 3D/4D printed functional composites, including the materials, shape memory/changing effects, self-monitoring/healing behaviors, and challenges surrounding additive-manufactured functional composites. Specifically, continuous fibers and matrices that provide functional roles are classified and discussed in detail. 4D printed shape memory and changing CFRPCs can retain their original shapes from a designed shape upon exposure to different external stimuli, including heat, electricity, humidity, and multi-stimuli activation. Furthermore, self-monitoring of structural health is achieved through the piezoresistive features of reinforced fibers in 3D printed CFRPCs. Finally, this review concludes with an outlook on the future research opportunities for 3D/4D printed functional CFRPCs.

3D/4D打印功能连续纤维增强聚合物复合材料:进展与展望

近年来，连续纤维增强聚合物复合材料3D/4D打印技术的创新为具有定制功能的复合材料的集成设计和制造开辟了新的视角。本文综述了3D/4D打印功能复合材料的现状，包括材料、形状记忆/改变效应、自我监测/愈合行为，以及添加剂制造的功能复合材料面临的挑战。具体而言，对提供功能作用的连续纤维和基质进行了分类和详细讨论。4D打印的形状记忆和变化的CFRPC在暴露于不同的外部刺激（包括热、电、湿度和多刺激激活）时可以从设计的形状保持其原始形状。此外，通过3D打印的CFRPC中增强纤维的压阻特性，可以实现结构健康的自我监测。最后，本文对3D/4D打印功能性CFRPC的未来研究机会进行了展望。
