Opis:
The polymer-matrix composites have been applied to regeneration of machine elements since many years. Their proprieties as well as range of using are known generally. However, no exact comparative data about technological factors influence on the adhesive-bonded joints properties, especially the influence of surface preparation. Authors in view of the wide possibilities of the use of such composites in the repair of machinery and equipment, the issue of assessing the impact of technological factors on the properties of adhesive joints made in this work. In this paper was presented the results of adhesive-bonded joints researches depending on the preparation of adhesive material and the surface condition of jointed elements. The tests were selected most often used adhesive material. Based on these results it can be stated that the composition of the adhesive composition and condition of the surface preparation jointed elements have a significant influence on the properties of connections. It is noted considerable variation bonding strength between various variants of the state of the surface. The composition of the adhesive has a significant effect on the properties of the connection. Deficiency and excess hardener content in weight reduces the adhesive strength of the adhesive connection.

Opis:
Numerous advantages of the bonded joints result in wide application in the aircraft, motor industry or powertrain components. These types of joints enable joining materials with different mechanical properties (e.g. Stiffness) and dimensions without structure change. Proper joint design limits the field of local stress concentrations or even eliminates them. The structural integrity of complete structure depends on the fatigue estimation of the bonded joint. Application of the finite element method to life prediction of the double lap bonded joint metal-composite-metal is presented. Three dimensional numerical models are generated by professional engineering software tools. The contact problem is modelled between the epoxy resin and metal and composite surfaces. A laminated composite consists of the epoxy woven carbon prepreg. Elasto-plastic materials models of the adhesion and metal and orthotropy composite model allowed determining the contact normal stress in the interfaces in each deformation increment which is induced by an external load. MSC.Marc was used to determine the strain and stress distribution in the double lap bonded joint including contact normal stress in the steel/adhesive and laminated composite/adhesive interfaces. Two numerical models of the double lap bonded joint were compared. The use of the presented method is more suitable for structure optimisation than numerical analysis.

Opis:
This paper describes a numerical analysis of adhesively bonded hot dip zinc coated sheet and titanium sheet and its comparison with the results of experimental tests. The study aims at presenting a comparative analysis of numerical calculation results with the results of strength test of the joints in question. Numerical simulations are an invaluable extension of experimental tests and, moreover, prove particularly useful at joint designing and analysis stages. The calculations were conducted with ABAQUS Standard software and allowed for the destructive force value obtained in experimental tests. Strength tests were conducted on single-lap adhesive joints for given structural materials; the samples were shear-loaded. The comparison of the results of experimental tests and numerical analysis led us to observe certain inconsistencies in the destructive force values, consequently providing information on the accuracy of a numerical model when compared with the actual model. Geometric model of the analysed single-lap adhesive joint, numerical model of the analysed single-lap adhesive joint, adhesive layer failure criterion description, visualisation of the analysed single-lap joint failure process, visualisation of adhesive joint failure stages of adhesive layer are presented.
