Adhesive bonding is one of many materials connecting methods. In the last ten years periods the bonding technology noted a boom almost in all industrial branches. The use of bonding technology in the engineering and repairing industry brings considerable savings. Saving in costs, in critical metallic materials and in time are reached and the decrease of the joint weight, too. Therefore the bonding technology pertains to the modern jointing methods even though it is a very old technique. The adhesive bonding technology is influenced by a number of factors which affect the adhesive bond strength. Correcting coefficients have to be considered in construction calculations too. The correcting coefficients correct the strength deviations caused by particular factors. In the paper there are published laboratory experiments results.

Adhesive Bonded Joints

Research of degradation medium occurring in agrocomplex at the current interaction with bonded joints strength and lifetime is desired owing to the possibilities of bonding applications in this dynamically developing field. The bonding technology is used in construction of machines, lines and devices of agriculture, forestry and food industry. Among the perspectives of bonding technologies the adhesive bonding can be considered thanks to its predominant pluses. At the bonding technology or more precisely adhesive bonding technology application the limits must be characterized, which occur in the process of application in the concrete medium. On the basis of characteristics and analyses the countermeasures eliminating the negative factors can be taken. Published results set themselves the goal to know degradation processes taking place in bonded joints contemporarily with taking account of adhesive/adherend interaction with accent on application in agriculture. Experimentally found results confirm the presumption of a significant portion of the adhesive layer on the adhesive bond strength decrease in the practice due to the degradation processes.

Adhesive bonding technology is successfully applied partly in the primary production, partly in the renovation in various fields of human activities. This fact emphasizes the importance of the partial factors research, which influence is essential for the quality, reliability and necessarily the usable life of bonded joints. The mechanical preparation of bonded surface is a varied process which influences directly the resultant bonded joint quality. The aim of the bonded surface mechanical preparation is the adhesion improvement in the adhesive – adherend interface. For mechanical preparation we use tools of defined cutting edge, by means of which we get the uniform surface texture, e.g. by milling. On the contrary such methods are more often used when the uniform surface cannot be reached. Shot blasting and grinding are significant representatives of these methods. The manual grinding can be significantly applied mainly in the agriculture. The absence of connected areas availability for the mechanical tooling and impossibility of their work clamping are the reasons for that. The breakwater in the sprinkler cistern restricting the liquid motion is the example.

Body Production

Recent trends in car body manufacturing indicate that the use of a consistent mix of lightweight materials in conjunction with adhesive bonding, not only allows substantial weight reduction, but can also drive down costs and potentially enables more intelligent designs. Yet, presently, it is highly desirable that the introduction of structural adhesives is made with minimum impact on the automotive body framing systems. Adhesives commonly deployed in car body production (i.e. body-in-white) are applied without any prior surface preparation and final curing is carried out during the baking process that follows the electrophoretic coating. Several structural adhesives have been tailored to the conditions dictated by the automotive production process. The aim of this work is to assess the mechanical properties of adhesive joints bonded with automotive grade hot setting epoxy adhesives employed for the assembly of frame and panels. Single-lap and T-joints were fabricated and adhesive hardening was carried out following the typical curing cycle employed in the process chain of automobile production. The resulting mechanical properties were assessed before and after exposure to a standard accelerated thermal cycling under controlled humidity. The evaluation of the mechanical behavior was done through a combination of testing and analysis, which included the assessment of fracture surfaces using optical microscopy to resolve the locus of failure.

Ayurveda in its principle has given importance to individualistic approach rather than generalize. Application of this examination can be clearly seem like even though two patients suffering from same disease, the treatment modality may change depending upon the results of Dashvidha Pariksha. Prakruti and Pramana both used in Dashvidha Pariksha. Both determine the health of the individual and Bala (strength) of Rogi (Patient). Ayurveda followed Swa-angula Pramana as the unit of measurement for measuring the different parts of the body which is prime step assessing patient before treatment. Sushruta and Charaka had stated different Angula Pramana of each Pratyanga (body parts). Specificity is the characteristic property of Swa-angula Pramana. This can be applicable in present era for example artificial limbs. A scientific research includes collection, compilation, analysis and lastly scrutiny of entire findings to arrive at a conclusion. Study of Pramana and its relation with Prakruti was conducted in 1000 volunteers using Prakruti Parkishan proforma with an objective of evaluation of Anguli Pramana in various Prakriti. It was observed co-relating Pramana in each Prakruti and Granthokta Pramana that there is no vast difference in measurement of head, upper limb and lower limb. The observational study shows closer relation of features with classical texts.

AbstractThe increasing use of fibre reinforced polymer composite materials in a wide range of applications increases the use of similar and dissimilar joints. Traditional joining methods such as welding, mechanical fastening and riveting are challenging in composites due to their material properties, heterogeneous nature, and layup configuration. Adhesive bonding allows flexibility in materials selection and offers improved production efficiency from product design and manufacture to final assembly, enabling cost reduction. However, the performance of adhesively bonded composite structures cannot be fully verified by inspection and testing due to the unforeseen nature of defects and manufacturing uncertainties presented in this joining method. These uncertainties can manifest as kissing bonds, porosity and voids in the adhesive. As a result, the use of adhesively bonded joints is often constrained by conservative certification requirements, limiting the potential of composite materials in weight reduction, cost-saving, and performance. There is a need to identify these uncertainties and understand their effect when designing these adhesively bonded joints. This article aims to report and categorise these uncertainties, offering the reader a reliable and inclusive source to conduct further research, such as the development of probabilistic reliability-based design optimisation, sensitivity analysis, defect detection methods and process development.

Mining Methods

Data-driven quality evaluation in the stamping process of car body parts is quite promising because dependencies in the process have not yet been sufficiently researched. However, the application of data mining methods for the process in stamping plants would require a large number of sample data sets. Today, acquiring these data represents a major challenge, because the necessary data are inadequately measured, recorded or stored. Thus, the preconditions for the sample data acquisition must first be created before being able to investigate any correlations. In addition, the process conditions change over time due to wear mechanisms. Therefore, the results do not remain valid and a constant data acquisition is required. In this publication, the current situation in stamping plants regarding the process robustness will be first discussed and the need for data-driven methods will be shown. Subsequently, the state of technology regarding the possibility of collecting the sample data sets for quality analysis in producing car body parts will be researched. At the end of this work, an overview will be provided concerning how this data collection was implemented at BMW as well as what kind of potential can be expected.
