This poses a significant limitation in the application of 3D-printed CFRP. While recent studies have focused primarily on characterizing fracture toughness, a substantial gap remains in developing innovative interlaminar damage-tolerant designs. The main contribution of this study is to implement an interlaminar hybridization strategy using a co-extrusion process that integrates carbon fibers, known for their low toughness, with Kevlar, which offers superior fracture toughness, to improve resistance to mode II delamination propagation. End-notched flexure (ENF) tests are conducted to characterize the initiation and propagation fracture toughness at pure carbon (C//C), pure Kevlar (K//K), and hybrid (C//K) interfaces using the compliance calibration method (CCM), direct beam theory (DBT), and compliance-based beam theory (CBBM). The most significant finding is that hybridization results in a remarkable difference of 709% in propagation toughness at the C//K interface, demonstrating a rising R-curve compared to the unstable delamination growth observed at the C//C interface.Fractographic analysis indicates that extensive Kevlar bridging behind the crack tip is the primary toughening mechanism. Furthermore, hybridization creates an intrinsic fracture process zone ahead of the crack, significantly enhancing energy absorption. The interaction between carbon and Kevlar, which leads to carbon pull-out, is identified as a positive side effect of hybridization. These findings provide critical insights into interlaminar bonding mechanisms influenced by hybridization, highlighting the potential for next-generation 3D-printed composites in real applications employing a damage-tolerant design philosophy.</div></div>","PeriodicalId":283,"journal":{"name":"Composites Science and Technology","volume":"264 ","pages":"Article 111126"},"PeriodicalIF":8.3,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143529268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By coating LM particles with carbon nanotubes (CNT), the LM@CNT particles that mimics a \"neuron\" structure was developed. LM@CNT was combined with silicone rubber (SR) to form the LM@CNT/SR, which exhibits micro-level thermal conductivity enhancement. The integration of LM@CNT in SR establishes a thermal conduction network, resulting in a thermal conductivity of 1.37 W/m/K for the LM@CNT/SR. Inspired by the growth rings in tree trunks, vertically aligned graphene films (VAGF) are ingeniously embedded in the composite material to enhance thermal conductivity at the macro-level. The results show that embedding 0.02 mm thick VAGF can increase thermal conductivity by 8.8 W/m/K, while 0.1 mm thick VAGF can achieve an increase of 24.7 W/m/K.

Furthermore, the LM@CNT/SR/VAGF demonstrates excellent stability, with negligible changes in thermal conductivity after nearly 2000 temperature cycles.
