Addressing this, the differences in structure and chemistry between hot and cold curing adhesives were investigated, focusing on bonding anodised aluminium joints. The structure of the bonding interface was analysed using Scanning Electron Microscopy (SEM), whereas the chemistry involved was determined through Fourier Transform InfraRed (FT-IR) and X-ray Photoelectron Spectroscopy (XPS). Lap-shear results showed that significant adhesion was achieved between the aluminium oxide coating and the hot- and cold-cure adhesives. The cold-cure adhesive was found to contain 10.6 % fewer hydroxyl groups at the bonding interface. Functional bonding groups corresponding to aluminium silicate bonds were detected at interface of anodised aluminium joints bonded with cold cure adhesives, but these bonds were absent at interface of joints bonded with the hot cure adhesive. Although differences in functional bond groups were found to exist at the interface between the anodised aluminium and cold or hot cure adhesives, all tested lap-shear joints exhibited cohesive failure regardless of the adhesive being hot or cold curing. Results from this investigation indicates that the lower lap-shear performance of anodised joints bonded with the cold cure adhesive compared to those bonded with the hot cure adhesive stems from differences in the bulk properties of the adhesives themselves, suggesting that the cold cure adhesives have inferior mechanical bulk properties compared to the hot cure adhesive.</div></div>","PeriodicalId":13732,"journal":{"name":"International Journal of Adhesion and Adhesives","volume":"143 ","pages":"Article 104173"},"PeriodicalIF":3.5,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145267432","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}

These boards are widely utilized in furniture, construction, and packaging due to their affordability and versatility. However, high flammability limits their broader industrial application. This study investigates the incorporation of aluminum hydroxide (Al(OH)₃) as a fire-retardant filler in <em>Acacia mangium</em> waste/polyurethane-based particleboards. The objective was to evaluate how varying Al(OH)₃ concentrations affect the physical, mechanical, thermal, and fire-resistant properties of the composites. Acacia mangium waste-based particleboards were prepared with different Al(OH)₃ loadings 0–7.5 wt% Al(OH)₃ to improve fire resistance while maintaining physical and mechanical performance. Particleboards were tested for water absorption (WA), modulus of rupture (MOR), and modulus of elasticity (MOE). Thermogravimetric analysis (TGA) and limiting oxygen index (LOI) tests assessed thermal stability and fire retardancy. Results showed improved water resistance, with WA reduced to 11.2 %, and a maximum MOE of 5174.5 MPa at 6 % Al(OH)₃. However, MOR decreased from 23.6 MPa (0 wt% Al(OH)₃) to 18.5 MPa at 6 % Al(OH)₃., indicating a trade-off between stiffness and rupture strength. TGA revealed that the third-stage maximum mass-loss temperature increased from 349.01 °C (0 wt% Al(OH)₃) to 394.18 °C at 6 wt% (+45.17 °C) and to 410.28 °C at 7.5 wt% (+61.27 °C), indicating enhanced thermal stability. and 6 wt% formulation achieved a LOI of 23 %, meeting the slow-burn criterion. Statistical analysis (ANOVA and Tukey HSD) confirmed the significant influence of Al(OH)₃ on all properties. The findings highlight that 6 % Al(OH)₃ offers an optimal balance between mechanical integrity and fire resistance. This formulation meets international strength standards and provides enhanced durability, making it suitable for applications requiring both flame retardancy and moisture resistance.</div></div>","PeriodicalId":13732,"journal":{"name":"International Journal of Adhesion and Adhesives","volume":"143 ","pages":"Article 104174"},"PeriodicalIF":3.5,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145266881","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}

These findings highlight the significance of stacking sequence in optimizing composite SLJ designs for structural applications. Since all joints demonstrated higher performance under tensile loading in the zero-direction, the study was extended to evaluate their behavior under multi-rate tensile testing.

We conducted a peel test of a composite film layer with EVA as the adhesive, considering the effects of peel angle, peel rate, and peel specimen width on the peel force. The experimental results indicate that under the same test conditions, the ratio of peel forces is approximately equal to the ratio of the widths of the peel specimens. The peel rate primarily affects the peel strength by influencing the viscoelastic response of EVA during the peel process, leading to a change in failure mode.

However, understanding and predicting their fracture behaviour, especially in Mode I, is important for ensuring structural integrity and reliability. This study focuses on evaluating two-dimensional numerical models of the Double Cantilever Beam (DCB) manufactured of composite laminates. It builds upon previous experimental studies related to bonding while considering the manufacturing process and associated uncertainties, using the Finite Element Method (FEM). Deterministic analyses were carried out to assess the advantages and disadvantages of the models. Based on these assessments, a numerical model was selected to perform non-deterministic studies and apply metamodeling to estimate fracture strength of Mode I DCB bonded composite joints. This involved generating numerical models using Python® scripts linked with Abaqus® software. A Design of Experiments (DoE) strategy was developed to reduce the number of experiments while evaluating the effect of various design parameters. The design variable space was defined in terms of the geometrical characteristics of the specimen and their material properties, encompassing a total of 11 parameters. In other words, this evaluation aims to determine how much each variable influences the energy release rate <span><math><mrow><mo>(</mo><msub><mrow><mi>G</mi></mrow><mrow><mtext>Ic</mtext></mrow></msub><mo>)</mo></mrow></math></span>. The Compliance-Based Beam Method (CBBM) was applied to determine the critical fracture energy in Mode I of the DCB bonded composite joint. From the DoE ranking, the five most influential variables were selected as design variables for the development of the surrogate model. It was noted that most of the variables exhibited epistemic uncertainty, particularly among the geometric variables. Subsequently, the training of the metamodel was conducted using Latin Hypercube Sampling (LHS) in conjunction with Efficient Global Optimization (EGO) defined by the optimized model. Overall, the proposed methodology effectively combines deterministic modelling, uncertainty quantification, and surrogate modelling to provide information into the fracture behaviour of bonded composite joints. The results indicate that the mechanical strength of the joint in Mode I, as predicted by the surrogate model, is strongly influenced by variables such as the energy release rate, adhesive and adherent thicknesses, fibre orientation, and initial crack length. Thus, this methodology helps the development of more robust design strategies for bonded composite structures subjected to out-of-plane stress components.</div></div>","PeriodicalId":13732,"journal":{"name":"International Journal of Adhesion and Adhesives","volume":"143 ","pages":"Article 104167"},"PeriodicalIF":3.5,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145267433","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}
