In this paper the impact of different thin silicone films and laser cleaning processes on the bond quality is assessed.

This work evaluates joining strategies for acrylonitrile butadiene styrene (ABS) using commercial epoxy and cyanoacrylate, pure acetone welding, and ABS-acetone blends at 5, 10, and 15 g per 50 mL. Single lap joints conforming to ASTM D3163 were prepared with line and concentric infill. Tensile tests measured tensile strength, elongation, and energy per bonded area, while microscopy and Fourier transform infrared spectroscopy assessed interfacial morphology and chemical change. Tensile tests revealed that all solvent-based joining strategies significantly outperformed commercial epoxy and cyanoacrylate adhesives, with the ABS-acetone blends even surpassing the strength of the monolithic specimens. The optimal formulation of 10 g ABS per 50 mL acetone maximized joint strength at 14.7 MPa, a 75 % improvement over the 8.4 MPa achieved by cyanoacrylate. Line infill patterns consistently delivered higher strength, attributed to raster alignment with shear and increased contact, while concentric infill provided greater elongation through greater local compliance and shear yielding. Microscopy and spectroscopy confirmed the mechanism as solvent-driven chain interdiffusion, which created a graded, conformal interphase, in contrast to the sharp boundaries and voids observed with traditional adhesives. These results demonstrate that the proposed up-cycled adhesive blend enables the fabrication of large-scale ABS components with joint strength exceeding that of the base material.</div></div>","PeriodicalId":13732,"journal":{"name":"International Journal of Adhesion and Adhesives","volume":"145 ","pages":"Article 104226"},"PeriodicalIF":3.5,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145615422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in these joint configurations, the adhesive is the weakest link. Therefore, parametric analysis is of utmost importance in understanding the mechanical behaviour and static strength of the bonded joints. The present study investigates the bond strength capability of epoxy-based adhesive used for woven-type Glass Fibre Reinforced Polymer (GFRP) in a Single Lap Adhesive Joint (SLAJ) configuration. 3D Cohesive Zone Modelling (CZM) is utilised to simulate the failure behaviour in the adhesive layer. There are very few studies conducted on the width parameter of SLAJ, and combined geometrical interacting effect analysis is scarce. In this study, three parameters constituting overlap length, overlap width, and thickness of adhesive in the joint are varied, and their responses are obtained in the form of shear stress, stiffness and peak load of the joint. A transition point is observed in the shear stress variation upon the change in the overlap length. A design space is constructed using a Central Composite Design (CCD) to acquire unique parametric combinations which retain most of the variability in the design space. The viability of this model is further verified by using a hybrid Adaptive Neuro-Fuzzy Logic Inference System (ANFIS) model. Latin Hypercube Sampling (LHS) generated a testing dataset used to evaluate the effectiveness of the neural network model. Two distinct optimisation algorithms, Genetic algorithm and Teaching-Learning Based Optimisation (TLBO), are used for optimal point acquisition, yielding maximum output.

Chemical analysis via TEM-EDX spectroscopy showed that the interdiffusion thickness between the adhesive molecules and the cured substrate resin was less than 30 nm, indicating its minor contribution to the adhesion. The formation of covalent bonds at the interface was reasonably assumed based on NIR measurement results which revealed at least 10 % of epoxides/amines in the cured substrate remained unreacted. Incorporation of the experimental findings into MD models of the bond interface enabled fair comparison of the mechanical testing and simulations, allowing discussion on the translation of MD-predicted properties into those measurable in macroscales. This led to an argument that the absorbed energy in a tensile-loaded MD model can be used to qualitatively assess the macroscale fracture energy of the corresponding bonded joint. The absence of interfacial covalent bonds combined with moisture absorption caused more than 90 % decrease in the MD-computed energy absorption, implying significant reduction in the fracture energy of the corresponding macroscale joint.
