Impact of 3D printing parameters of short carbon fiber reinforced polymer CFRP on the mechanical and failure performance: Review and future perspective

Despite the fact that manufacturing techniques of continuous carbon fiber reinforced polymer produce high quality and strong structures, 3D printed short carbon fiber reinforced polymers CFRP via Fused Deposition Modeling (FDM) is a promisingtechnology that is able to utilize excellent mechanical properties and customized structure geometries that can serve a wide range of different applications in the industrial sector. The work relevant to this topic is very lacking in the literature and acted as a motivational point for the current review. In this work, a comprehensive review of the impact of the 3D printing parameters of CFRP composite structures on the material mechanical properties has been conducted in this article. In addition, the most common failure mechanisms associated with 3D printing short CFRP along with various techniques developed to improve the printed structures against failure have been extensively discussed. Furthermore, the review will include insights into the future of 3D-printed CFRP and an optimization technique for specifying the ideal printing parameters tailored to certain applications.
