However, quantitatively measuring this strength remains challenging due to the complex geometries and microscale dimensions of fillers. This study presents a novel experimental method to measure the interfacial bonding strength between microparticles and the matrix in microcapsule/epoxy composites. A stepped microchannel structure was fabricated by assembling glass capillaries with inner diameters of 100 μm and 400 μm. This structure facilitated the formation of fiber specimens where a single microcapsule was embedded at the junction of two epoxy fibers with different diameters. After the matrix cured, the external glass capillaries were removed, yielding specimens designed to fail precisely at the interface between the microcapsule and the 100 μm epoxy fiber. The critical debonding load and contact area were meticulously measured to calculate the interfacial bonding strength. The effects of surface modification of microcapsules using three silane coupling agents were systematically investigated. All coupling agents significantly enhanced interfacial bonding strength, with the highest improvement reaching 90.2 %. This innovative method offers a reliable and quantitative means of assessing interfacial bonding strength in composite materials. It holds potential to accelerate the development of high-performance composites and deepen our understanding of their interfacial behaviors.</div></div>","PeriodicalId":283,"journal":{"name":"Composites Science and Technology","volume":"265 ","pages":"Article 111134"},"PeriodicalIF":8.3,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143579261","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}

The most prominent feature of this technology lies in the introduction of CNT film and the application of electric current. However, they inevitably affect the interfacial bonding and molding properties of composites. So, the mechanism and law behind interfacial bonding is crucial for developing the high-performance curing process. To make them clear, three kinds of layup schemes of CNT film/carbon fiber prepreg were designed in this study, and then the composite unidirectional plates were prepared by using the electrothermal in-situ co-curing technology with CNT film. Compared with the same layup structure by conventional thermally cured, the mechanical properties of the composites by electrothermally cured were significantly higher. For the reason of which, the interfacial enhancement mechanism is revealed as follows: (1) the electrical treatment modifies the surface structure of the carbon fiber, thereby increasing the interfacial bonding strength between the carbon fiber and resin; (2) the pre-curing effect induced by electrothermal heating within the CNT film enhances the interfacial bonding strength between the CNT film and resin; (3) the combined effects of electrical treatment and pre-curing increase the thickness of the interfacial layer, reducing the modulus gradient and stress concentration at the interface, thereby enhancing the strength of composites.
