Three-dimensional printing of CFTPCs opened up a new strategy for the fabrication of composites with complicated structures, low cost, and short production cycles. However, a traditional 3D printing process usually causes poor impregnation of the fiber or surface damage of the fiber due to the short impregnation time or high viscosity of the thermoplastic resin. Here, continuous carbon fiber\/poly(ether-ether-ketones) (CCF\/PEEK) wrapped yarn was fabricated via powder impregnation and using double spinning technology for the 3D printing. The concentration of PEEK powder suspension and wire speed were optimized as 15% and 2.0 m\/min. The twist of wrapped yarn was optimized as 1037 T\/m. Mechanical testing showed that the 3D-printed composite wire had excellent tensile and bending strength, which was about 1.6~4.2 times larger than those without the powder pre-impregnation process. It is mainly attributed to the improved impregnation of the CF which took place during the powder pre-impregnation process. We believe that our research on wrapped yarn for 3D-printed composites provides an effective strategy for the 3D printing of composites with enhanced mechanical properties.<\/jats:p>","DOI":"10.3390\/ma16031168","type":"journal-article","created":{"date-parts":[[2023,1,30]],"date-time":"2023-01-30T02:01:18Z","timestamp":1675044078000},"page":"1168","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Two-Step Preparation of CCF\/PEEK Wrapped Yarn for 3D Printing Composites with Enhanced Mechanical Properties"],"prefix":"10.3390","volume":"16","author":[{"given":"Jianghu","family":"Zhang","sequence":"first","affiliation":[{"name":"State Key Laboratory for Modification of Chemical Fibers and Polymer Materials, College of Materials Science and Engineering, Donghua University, Shanghai 201620, China"},{"name":"Institute of Functional Materials, Donghua University, Shanghai 201620, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Shen","sequence":"additional","affiliation":[{"name":"Institute of Functional Materials, Donghua University, Shanghai 201620, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3179-8214","authenticated-orcid":false,"given":"Lili","family":"Yang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Modification of Chemical Fibers and Polymer Materials, College of Materials Science and Engineering, Donghua University, Shanghai 201620, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dengteng","family":"Ge","sequence":"additional","affiliation":[{"name":"Institute of Functional Materials, Donghua University, Shanghai 201620, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Shi, J., Mizuno, M., Bao, L.M., and Zhu, C.H.
