However, this process faces challenges, as oxygen gas during heating has difficulty penetrating dense composites, resulting in low-quality recovered carbon fibers (rCFs). It was demonstrated that high-grade rCFs could be obtained by combining the thermal process with a short period of electrical treatment (ET). In this study, we investigated the effects of fiber orientation and matrix type on the separation efficiency (SE) by ET using uni-directional (UD-) and plain-weave (PW-) CFRPs, as well as twill-weave CFRTP. The results indicated that the SE value of UD-CFRP was nearly equal to that of PW-CFRP, suggesting that fiber orientation did not significantly affect resin removal. In contrast, the SE value of CFRTP was four times higher than that of CFRPs at a low constant voltage, as the separation resistance of the matrix decreased owing to thermal-oxidative degradation caused by moderate temperatures resulting from Joule heat and oxygen generated on the anode side.</div></div>","PeriodicalId":384,"journal":{"name":"Materials Letters","volume":"381 ","pages":"Article 137786"},"PeriodicalIF":2.7,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142747077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
