Correction to: Interfacial behaviors of continuous carbon fiber reinforced polymers manufactured by fused filament fabrication: A review and prospect

Continuous fiber reinforced polymers composites have significant potential due to their high specific strength and high specific modulus. But there are some limitations on manufacturing and maintenance for the composites using existing manufacturing technologies. Meanwhile, the increasingly advanced 3D printing technology, with advantages on complex components building, no need for assembling operations and precise entity replication, has brought new hope for the manufacture and application of continuous fiber reinforced composites. However, compared to traditionally manufactured composites, poor interfacial adhesion is the main weakness of 3D printed composites. In the present work, a comprehensive review study on the identification, categories, characterization and measuring methods for interfaces in 3D printed composites is presented. Particularly, the effects of materials, processing and design parameters on the interfacial properties and mechanical behaviors of 3D printed composites are systematically discussed. Based on these investigation and discussion, compilation of effective methods and technologies is presented to improve the interfacial adhesion and reduce the generation of voids. Also, modeling and simulation approaches are also presented for the special case of 3D printed composites. This work therefore intends to provide a reference source regarding interfacial properties, processing control, processing scalability and product performance of 3D printed composites, that could help researchers proceed and make contributions to this research field.
