摘要
因设计自由度高、无需模具和快速制造等优点,连续纤维增强3D打印已成为当今最具创新性的先进复合材料成型技术之一.本文综述了连续纤维增强3D打印复合材料工艺缺陷及失效行为的最新研究进展,引入了"干/湿/干湿-混合"的概念对打印工艺进行了系统性分类阐述,重点介绍了由于工艺过程引入的三种缺陷及其特点.随后,归纳了连续纤维增强3D打印复合材料的失效力学行为,并分析了引发失效的主要原因.最后,针对如何减少工艺缺陷、改善失效模式和降本增效对连续纤维增强复合材料3D打印技术的未来进行了展望.
Abstract
Constraint-free design,rapid production,and the absence of mold requirements are just a few of the reasons why continuous fiber-reinforced 3D printing(CFR3DP)has emerged as one of the most innovative advanced composite manufacturing technologies nowadays.This study examines the recent developments in research concerning process defects and the failure behaviors of CFR3DP.In order to systematically categorize the printing process,the notion of"dry/wet/dry-wet-mixed"has been introduced,with an emphasis on the three distinct groups of defects that may be introduced during the additive manufacturing process.Following this,an analysis was conducted to summarize the failure behaviors of CFR3DP while also identifying the primary causes of failure.In conclusion,we propose the prospect of CFR3DP with respect to cost reduction,efficiency,the mitigation of process defects,and improvement of failure mode.
