The Journal of Adhesion (J ADHESION )

Publisher: Taylor & Francis

Description

This journal is of very broad interest to the large technical community concerned with the development of an understanding of the phenomenon of adhesion and its practical applications. The art of adhesion is maturing into a science which requires a broad, coordinated interdisciplinary effort to provide an understanding of its complex nature and numerous manifestations. The Journal of Adhesion provides a forum for discussion of the basic and applied problems in adhesion. Papers are considered relevant if they contribute to the understanding of the response of systems of joined materials to mechanical or other disruptive influences. Experimental papers are required to incorporate theoretical background and theoretical papers must relate to practice.

    ABSTRACT: The growing demand in lighter and safer structures generates the requirement of lighter joining strategies, particularly for lightweight metal alloys, composites, and also joining dissimilar materials together. Titanium alloys stand out as the conventional choice for materials for light weight structures. Adhesive bonding of titanium is an appealing route for joint design, also for the possibility of joining it with dissimilar materials. The realization of a strong joint depends not only on the joint design and type of adhesive, but also on the preparation of the adhering surface. Laser texturing presents advantages compared to common surface preparation processes in terms of eco-compatibility, energetic efficiency, ease of manufacturing, and repeatability. This work presents a preliminary investigation on laser texturing of Ti6Al4 V alloy with a pulsed fiber laser source with the aim to increase surface adhesion for bonding. Particularly, different surface textures are proposed, and laser machining strategies are developed. The results showed that laser texturing provided up to eightfold and 30% higher shear strength compared to plain and sand blasted surfaces, respectively. Failure analysis showed that a margin of improvement is still possible by adapting the surface texture for better cavity filling and reducing surface damage caused by the laser treatment.

    ABSTRACT: The loop tack, peel strength and shear strength of cross-linked epoxidized natural rubber (ENR-50)/acrylonitrile-butadiene rubber (NBR) blend adhesives were studied in the presence of coumarone-indene resin. Benzoyl peroxide was used as the cross-linking agent with dosage ranging from 1 to 5 parts per hundred rubber by weight (phr). Toluene was used as the solvent throughout the investigation. A SHEEN hand coater was used to coat the adhesive on a polyethylene terephthalate substrate at 60 and 120 μm coating thickness. The adhesive was cured at 80°C for 30 min prior to testing on a Lloyd adhesion tester operating at various testing rates from 10 to 60 cm min−1. Results show that loop tack and peel strength of the ENR-50/NBR adhesives pass through a maximum value at 4 phr of benzoyl peroxide dosage. This observation is attributed to the increase in cohesive strength which culminates at 4 phr benzoyl peroxide loading. However, shear strength increases steadily with dosage of benzoyl peroxide due to the continuous increase in the cohesive strength as crosslinking of the rubber blend proceeds. In all cases, the adhesion properties increase with increasing coating thickness and testing rates.

    ABSTRACT: Although it seems that gecko adhesion research is a relatively young branch of science, this recently rediscovered work presents some very old studies with quite remarkable findings. The publication of Dr. F. Weitlaner from 1902 is very impressive, as it covers many recently published topics and – even more impressively – often comes to the same conclusions and provides similar results compared with current publications. Weitlaner published his paper in German which was – at that time – very common in science. This makes it almost impossible for today's international community of bioinspired adhesion researchers to enjoy and appreciate this early gem of scientific work. Thus, we have decided to translate his paper in the hope that it finds the attention it deserves and that it inspires us to stay curious and pursue answers to the questions which have been asked for over a century.

    ABSTRACT: In order to enhance the strength of adhesively bonded single-lap joints (SLJs), the adhesively bonded SLJs with reinforcements were proposed. Adhesively bonded SLJs of different substrates and with different reinforcements were investigated experimentally and numerically. Scanning electron microscopy was performed on the fracture surfaces of the joints to analyze the failure mechanism. Shear stresses and peeling stresses of the adhesive layer were calculated with finite element analyses (FEA). Results showed that the deformation of the joints decreased with an increase in stiffness at the end of the overlap region. The strength increase in adhesively bonded SLJs with reinforcements was validated by the results from experimental tests and FEA.

    ABSTRACT: Grafting of methyl methacrylate (MMA) and styrene (St) onto polychloroprene latex (CRL) was carried out successfully using emulsion polymerization. The chemical structure of the grafted copolymer was characterized using Fourier transform infrared spectroscopy. The compatibilizing effects of the grafted polymer CRL-g-(MMA-co-St) on the CRL/styrene-acrylate emulsion (SAE) blend were investigated using scanning electron microscopy (SEM), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and mechanical testing. The results showed that the mechanical properties of the contained CRL-g-(MMA-co-St) blend improved significantly in comparison to those of the simple CRL/SAE blend. For the contained CRL-g-(MMA-co-St) blend, the maximum tensile strength (6.72 MPa) and the maximum elongation at break (1142.6%) were obtained when the content of SAE was 60% (occupied by the total dry weight). At the same content of SAE, the T-peel and lap shear strengths of the contact adhesive derived from the contained CRL-g-(MMA-co-St) blend were 5.3 N/mm (canvas to canvas) and 1.8 MPa (plywood to plywood), respectively. The grafted copolymer CRL-g-(MMA-co-St) showed a remarkable compatibilizing effect on the CRL/SAE blends by drastically improving their mechanical properties.

    ABSTRACT: In this paper, the fracture toughness parameters of two types of dentistry cement have been investigated based on numerical and experimental analysis. Dentistry cements are largely applicable and useful when it comes to mending teeth and are used as resin and filler. Composite cement and adhesive resin cement are among the helpful cements in dentistry. As a result of production and the loading conditions in the mouth, the generation of micro-cracks is inevitable. In this research, by producing butterfly Arcan samples including crack and by loading those in different angles, pure mode-I, pure mode-II, and mixed-mode fracture data were obtained. The experiments were conducted by an Arcan fixture and loading device, which had the ability of investigating the fracture parameters of materials in different loading angles. By calculating the geometrical correction factors by using ABAQUS finite element software, fracture toughness and critical energy release rate have been obtained. Also, the effects of crack length, elasticity modulus, and Poisson's coefficient on the fracture parameters and energy release rate in different loading angles have been studied using numerical analysis.

    ABSTRACT: This paper focuses on a new coupling solution for determining the elastic interfacial shear and normal stresses in an adhesive joint between a strengthening plate and a simply supported beam. The mismatch of the curvatures in the beam and plate is considered by including both the effect of the adherend shear deformations and the prestressed laminates model. This new method leads to the coupling of governing differential equations for the interfacial shear and normal stresses. Most of the other solutions in the literature assume that the beam and plate have an equal curvature to uncouple this effect. In this paper, however, a solution is presented to calculate the interfacial stresses of beams strengthened with a prestressed composite plate having a new rigidity model coupled with the shear lag effect, which are neglected by the previous studies. It is found that the present method can predict accurately stresses in the interior and near the ends of the adhesive layer, where the stress fields can be significantly influenced by the edge effects. A parametric study was carried out to show how the stress concentration and distribution are influenced by the dimensions of the adherends and the material properties of the strengthened beam.

    ABSTRACT: Quantitative assessment of adhesive bond strength on composite surfaces with respect to silicone contamination is presented and discussed. By using X-ray photoelectron spectroscopy, the precise surface contamination level was determined. When correlated with adhesive bond strength measurements, low-, medium-, and high-risk contamination levels were identified.

    ABSTRACT: The effect of kaolin loading on the viscosity and shear strength of natural-rubber-based pressure-sensitive adhesive was studied using coumarone-indene resin, toluene, and polyethylene terephthalate as tackifier, solvent, and substrate, respectively. Kaolin loading ranged from 10 to 60 parts per hundred parts of rubber (phr) whereas the tackifier content was fixed at 40 phr. The viscosity and shear strength—from lap shear test—were determined by a Brookfield viscometer and Lloyd adhesion tester, respectively. Results show that viscosity increases with increasing kaolin loading. However, shear strength increases up to 20 phr kaolin loading, after which it decreases with further filler loading. This observation is attributed to the culmination of cohesive strength at the optimum loading of kaolin filler. For a fixed kaolin loading, the shear strength increases with coating thickness and testing rate.

    ABSTRACT: The drive towards greater use of fiber-reinforced composites in primary structures, such as aircraft structures and wind turbines that are increasingly unitized, calls for advanced repair techniques that can restore the structural integrity and geometry. Two such repair techniques are stepped repairs and scarf repairs. Under certain conditions, stepped repairs are easier to perform than scarf repairs, but the step corners may cause high level of stress concentrations negatively affecting the strength of the repair. This paper presents an investigation of the effect of step corners on the fracture behavior of stepped joints under compressive loading, particularly after subjecting it impact damage. Joints featuring different corner radii were tested under compressive loading, and results showed that the impact damage reduced the compressive strength, to marginally below the compression-after-impact strength of composite laminates. The findings reveal that stepped repairs can be designed to rival the performance of scarf repairs, due to the similarity in the inherent stress concentrations at ply terminations in both repair configurations.

    ABSTRACT: Airworthiness certification is required when bonded repairs are made to primary composite structure in situations where damage has reduced or has the potential to reduce residual strength to below the design ultimate strength. Generally, certification of bonded primary structure poses many difficulties. As most repairs are one-off events meeting these certification requirements is especially challenging since demonstration by testing will generally not be possible or cost-effective. This paper discusses options for addressing the two key issues relating to certification: (a) how to validate initial and enduring bond strength of adhesive bonds, mainly given the inability of conventional non-destructive inspection to provide this assurance and (b) how to develop acceptable generic design allowables for bonded repairs which represent actual failure modes – especially for cyclic loading, since validation by testing of simulated repairs will generally be infeasible. It is concluded that proof testing of bonded repair coupons is a promising approach for validating bond strength and fatigue testing of representative bond joint specimen can provide generic allowables for patch design. For hidden structure or very high value repairs structural health monitoring of repairs based on a strain-transfer approach offers considerable promise.

    ABSTRACT: Application of 1% hydrofluoric acid (HFA) to improve the repair bond strength of a microhybrid (Z250; 3 M/ESPE) and a nanofilled dental composite (Supreme XT, 3 M/ESPE) was investigated. Aged composites were etched using 1% HFA for 10, 30, or 60 s. Negative (non-etched) and positive (10% HFA for 60 s) control groups were tested. The surfaces received a layer of a silane and adhesive (Single Bond 2; 3 M/ESPE). Cylinders of fresh composite (n = 15 per group) were built up and a shear bond strength test was carried out after water storage for 24 hr or 6 months. Surface topography was assessed using atomic force microscopy (AFM). For the nanofill at 24 hr, all etching regimens yielded higher bond strengths than the negative control. After 6 months, the negative and positive controls showed lower bond strength than 1% HFA for 30 s. For the microhybrid, the negative control generally showed lower bond strength at 24 hr, while all groups had similar results after 6 months. Only the positive controls showed lower bond strengths after 6 months. AFM analysis showed that the nanofill was more susceptible to acid-etch roughening. In conclusion, exposure to 1% HFA may improve the repair bond strength of dental composites.

    ABSTRACT: This study compared the effect of physicochemical surface conditioning methods on the adhesion of bis-GMA-based resin cement to particulate filler composite (PFC) used for indirect dental restorations. PFC blocks (N block = 54, N block = 9 per group) were polymerized and randomly subjected to one of the following surface conditioning methods: a) No conditioning (Control-C), b) Hydrofluoric acid (HF)etching for 60 s (AE60), c) HF for 90 s (AE90), d) HF for 120 s (AE120), e) HF for 180 s (AE180), and f) air-abrasion with 30 µm silica-coated alumina particles (AB). The conditioned surfaces were silanized with an MPS silane, and an adhesive resin was applied. Resin composite blocks were bonded to PFC using resin cement and photo-polymerized. PFC–cement–resin composite blocks were cut under coolant water to obtain bar specimens (1 mm × 0.8 mm). Microtensile bond strength test (μTBS)was performed in a universal testing machine (1 mm/min). After debonding, failure modes were classified using stereomicroscopy. Surface characterization was performed on a set of separate specimen surfaces using Scanning Electron Microscopy (SEM), X-Ray Dispersive Spectroscopy (XDS), X-Ray Photoelectron Spectroscopy (XPS), and Fourier Transform-Raman Spectroscopy (FT-RS). Mean μTBS (MPa) of C (35.6 ± 4.9) was significantly lower than those of other groups (40.2 ± 5.6–47.4 ± 6.1) (p p > 0.05). Failure types were predominantly cohesive in PFC (34 out of 54) followed by cohesive failure in the cement (16 out of 54). Degree of conversion (DC) of the PFC was 63 ± 10%. SEM analysis showed increased irregularities on PFC surfaces with the increased etching time. Chemical surface analyses with XPS and FT-RS indicated 11–70% silane on the PFC surfaces that contributed to improved bond strength compared to Group C that presented 5% silane, which seemed to be a threshold. Group AB displayed 83% SiO2 and 17% silane on the surfaces.

    ABSTRACT: Timber engineering sets high expectations on adhesive bonding as a joining method to overcome a series of limitations related to partly obsolete traditional techniques. Research on adhesively bonded timber joints has proved their superiority over mechanical fasteners in terms of strength and stiffness, but this research was often limited to softwood. Despite its abundant availability in Central Europe and its high mechanical resistance, beech is only rarely considered as a structural material. Furthermore, research on adhesively bonded timber joints almost exclusively focused on tests at room temperature. Elevated temperatures, however, are critical in conjunction with adhesives, making it paramount to shed more light on that particular aspect. Based on experimental and numerical investigations, it was found that the capacity of adhesively bonded hardwood joints increased asymptotically with overlap length to a ceiling value; furthermore, it was concluded that temperature negatively impacts capacity. Glass transition temperature, T g, marked a clear transition, but joints still sustained relatively high loads beyond T g. A probabilistic approach was validated and successfully applied to predict the joint capacity. The research contributes to fill knowledge gaps by offering the basis for subsequent dimensioning methods that at term will enable practitioners to design their structures accordingly.

    ABSTRACT: The effect of an adhesive support on the Mixed-Mode fatigue properties of a metal-to-metal bonded interface was evaluated. Pure Mode I, pure Mode II, and Mixed-Mode fatigue disbond tests were conducted on supported and unsupported bonded samples. The fracture surfaces were observed and related to the fatigue disbond growth rate. The supporting system analyzed was found not to affect the fracture surface under Mode I loading, resulting in similar disbond growth rates for both supported and unsupported bonds. However, under Mixed-Mode and Mode II loading the supporting system improved the fatigue resistance. The improvement was related to different failure mechanisms caused by the supporting system such as Mode II load bearing and a change in the disbond path.

    ABSTRACT: This work studies optimal shapes of peeling films considering different peeling directions. A cohesive zone model is used to capture normal and tangential forces during peeling. The strip is modeled by nonlinear finite elements based on geometrically exact beam theory. Criteria for optimization are proposed that account for the strain energy during deformation, the overall peeling energy, and the maximum peeling forces. These criteria are first analyzed for various test geometries and then considered for computational optimization. Two cases are considered: Optimization for single direction and optimization for multiple directions. The later allows the determination of strip shapes that provide strong attachment and easy detachment under different peeling angles.
