Fifty sound third molars were sectioned, restored with resin composite (Filtek Z350 XT, 3M/Solventum), and embedded in polyester resin and low viscosity vinyl polysiloxane (Panasil, Ultradent Products). Fifty teeth were allocated into the following five groups (n = 10): MCDI - mechanically cycled in distilled water, MCAS - mechanically cycled in artificial saliva, MCDC - mechanically cycled under dry conditions, TC - thermocycled and CO - control (left uncycled). Mechanical cycling was performed using 500,000 fatigue cycles under a 130 N load at 2 Hz in an electromechanical testing machine (MSFM, ElQuip), while thermal cycling (MCT, Elquip) was conducted for 5000 times. All samples were then sectioned into beams (1 mm<sup>2</sup>) and subjected to μTBS testing in a universal testing machine (EZ Test, Shimadzu). Subsequently, failure modes were evaluated under a stereomicroscope and classified as adhesive (AD), cohesive within dentin (CD), cohesive within resin (CR), or mixed (MX). Data were analyzed using one-way analysis of variance, Tukey's test and chi-square test (α = 0.05). MCDI, MCAS and MCDC groups did not differ in μTBS, but showed significantly lower values than CO group (p = 0.009). TC did not differ from any of the other four groups. Groups differed in failure mode (p = 0.004), with AD ruptures being predominant in the groups MCDI and MCAS. MCDC group had significantly lower frequency of AD failures. CR failures was the most common type failure in the TC group. In the MCDI group, the proportion of CR failure was 2.5 times higher than CD failure, but reversed in the MCAS group. It was concluded that as far as the occurrence of aging of resin composite-dentin interface is a goal, regardless of the testing condition, mechanical cycling would be preferable over thermal cycling, as the latter did not cause discernible reduction in bond strength in comparison to uncycled counterparts.</div></div>","PeriodicalId":13732,"journal":{"name":"International Journal of Adhesion and Adhesives","volume":"142 ","pages":"Article 104106"},"PeriodicalIF":3.5,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144721373","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, previous studies have shown that effective surface treatment of PBF-LB-Ti6Al4V is still crucial to prevent interfacial failure in adhesive bonds. In particular, laser treatment has demonstrated significant potential as a surface preparation process. Therefore, in this work, the effects of laser treatment on the adhesive bond performance of metal-metal joints were investigated for three different laser fluences. Surface characteristics were evaluated using scanning electron microscopy, confocal laser scanning microscopy and ion beam cross-section polishing. Laser-induced residual stresses in the titanium were measured by X-ray diffraction. The quasi-static bond strength was assessed for tensile loading via centrifugal adhesion testing and for mode I loading by double cantilever beam testing. Moreover, the surface treatment effects on environmental durability and fatigue performance were examined through single step-lap joint testing. It was found that the thickness and uniformity of the laser fluence-dependent nanoporous oxide layer are the decisive factors influencing quasi-static and fatigue adhesive bond performance. The laser fluence impact on the bond strengths was found to be significant, however, not for tensile loading. The overall best bond performance was achieved with the highest applied laser fluence, which produced a thicker and highly uniform oxide layer. Compared to the as-built surface state (i.e., degreased PBF-LB-surface), an increase of up to 52 % in tensile bond strength and around 600 % in mode I fracture toughness was achieved with laser treatment. Moreover, the tensile shear bond strength after hydrothermal aging was improved by up to 79 %, and the fatigue lifetimes were significantly enhanced as well.</div></div>","PeriodicalId":13732,"journal":{"name":"International Journal of Adhesion and Adhesives","volume":"142 ","pages":"Article 104114"},"PeriodicalIF":3.2,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144713159","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}

The research introduces a novel approach to enhance energy absorption in automotive structures. To predict the average crushing force of these hybrid designs, theoretical models were developed and validated, combining the high strength and specific stiffness of composites with the structural rigidity of metals. Validation through experimental testing and finite element analysis showed strong alignment with theoretical predictions. The results suggest that increasing the fiber orientation angle, the thickness of the layers, and the quantity of CFRP layers generally boosts the energy absorption capacity. A finite element model was developed to evaluate these hybrid structures, focusing on five different composite ply angles: [+15/-15], [+45/-45], [90/90], [0/90], and [90/0]. The number of composite layers ranged from 2 to 8, with both uniform and variable thicknesses considered. Furthermore, an alpha factor was applied to evaluate local reinforcement effects. Findings showed that in comparison to energy absorbers made from aluminum or aluminum/composite materials, the adhesive bonding in the locally reinforced (Al-CFRP) specimen enabled the composite to enhance its energy absorption by conforming to the aluminum's collapse behavior, resulting in a consistent collapse mode. It was also found that the loading rate has minimal influence on the deformation pattern in both hybrid and single-material tubes. However, the energy absorption capacity of hybrid and CFRP tubes was considerably lower under dynamic loading compared to quasi-static loading. The effects of impact velocity and stacking sequence on the Dynamic Amplification Factor (DAF) were analyzed, This factor is important in simple design procedure as it can be used to estimate the dynamic effect from the static analyses without con ducting actual dynamic analyses or tests. Interestingly, the DAF for hybrid structures was lower than that of aluminum tubes, suggesting that lateral inertia effects in hybrid structures are diminished relative to empty tubes.</div></div>","PeriodicalId":13732,"journal":{"name":"International Journal of Adhesion and Adhesives","volume":"142 ","pages":"Article 104112"},"PeriodicalIF":3.2,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144704768","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}

A multiscale investigation on improving the adhesion property of SFP material using interfacial modification. Firstly, pull-off tests were conducted to assess the adhesion properties of SFP at the macroscale, considering grout materials of different strengths and aggregates with varying characteristics under interfacial modification. Secondly, contact angle tests were performed to analyze changes in the surface free energy of the asphalt interface in SFP at the mesoscale. Finally, atomic force microscopy (AFM) was utilized to evaluate the adhesion performance of the asphalt interface in SFP at the microscale after interfacial modification. Experimental results show that the proposed method significantly enhances the adhesion properties of SFP, with bond strength increasing by up to 165.6 % in SFP formed with alkaline aggregates. After immersion in a silane coupling agent solution, micro-protrusions form on the asphalt surface, increasing contact area and creating a modification layer that strengthens adhesion. Surface free energy rises by 39.79 %, improving wettability and molecular interactions.
