Saeedifar, M. (author), Saleh, M. (author), Krairi, Anouar (author), Teixeira De Freitas, S. (author), Zarouchas, D. (author)The present study proposes a comprehensive integrity assessment approach for a full-scale adhesively-bonded bi-material joint for maritime applications. The joint represents a cross-section of the bond-line connection of a ship with a steel hull and a sandwich composite superstructure. The full-scale joint consists of a sandwich composite...journal article 2023

Tomić, Nataša Z. (author), Saeedifar, M. (author), Saleh, M. (author), Marinković, Aleksandar (author), Zarouchas, D. (author), Teixeira De Freitas, S. (author)The aim of this research was to investigate the self-healing potential of damaged Al joints when bonded using novel eco-epoxide adhesives derived from tannic acid (TA). Two eco-epoxy components based on TA, (A) glycidyl ether and (B) glycidyl phosphate ester of TA, were produced. The effect of the eco-epoxy components on the self-healing...journal article 2022

Saleh, M. (author), Budzik, Michal K. (author), Saeedifar, M. (author), Zarouchas, D. (author), Teixeira De Freitas, S. (author)Thicker bondlines along with manufacturing-tolerant and fracture-resistant adhesives are trends visible across different industries, especially maritime. In this work, two contrasting adhesives: an elastic-brittle epoxy-based, and a nonlinear-ductile methyl methacrylate (MMA) are characterized and compared via tensile, compact tension (CT)...journal article 2022

Tomić, Nataša Z. (author), Saleh, M. (author), Saeedifar, M. (author), Marinković, Aleksandar (author), Teixeira De Freitas, S. (author)The aim of this paper is to study the self-healing capability of fractured Al joints bonded with novel eco-epoxide adhesives synthesized from a bio-renewable raw material (tannic acid – TA). Two synthesized eco-epoxy components based on TA, (A) glycidyl ether and (B) glycidyl phosphate ester of TA, were used as a replacement for the toxic epoxy...journal article 2021

Saeedifar, M. (author), Saleh, M. (author), Nijhuis, Peter (author), Teixeira De Freitas, S. (author), Zarouchas, D. (author)This study is devoted to the use of acoustic emission technique for a comprehensive damage assessment, that is, damage detection, localization, and classification, of an aeronautical metal-to-composite bonded panel. The structure comprised a titanium panel adhesively bonded to carbon fiber–reinforced plastic omega stringers. The panel contained...journal article 2021

Saleh, M. (author), Saeedifar, M. (author), Zarouchas, D. (author), Teixeira De Freitas, S. (author)Mechanics of double-lap Steel-to-CFRP adhesively-bonded joints loaded in tension are investigated experimentally using Digital Image Correlation (DIC) and Acoustic Emission (AE), analytically using a one-dimensional closed-form solution and numerically with Finite Element analysis. The double-lap bi-material joints are fabricated of a steel core...journal article 2020

Saeedifar, M. (author), Saleh, M. (author), Teixeira De Freitas, S. (author), Zarouchas, D. (author)The aim of the present study is to characterize the damage in bi-material steel-to-composite double-lap adhesively-bonded joints using Acoustic Emission (AE). Two different structural adhesives, a ductile (Methacrylate-based) and brittle (Epoxy-based), were used to bond CFRP skins to a steel core. The fabricated joints were loaded in tension...journal article 2019
