Induction heating was used to join basalt fiber reinforced polymer laminates (BFRPL) using the process called inductive contact joining (ICJ). Two other mechanical processes, nut and bolt (NB) two-piece hollow riveting (2PR), were compared ICJ. The obtained joints evaluated tensile shear tests by analyzing fractured surfaces. Furthermore, simulation of ICJ estimate effective parameters. Joints ...

Background The application of carbon-fiber reinforced plastics offers a high potential to decrease the weight of structural parts, without decreasing the performance of the product. Thus, the general and specific efficiency (e.g. eco-efficiency) is enlarged [1, 2]. Unfortunately, there are significant challenges within the assembly respectively joining process of CFRPparts, especially if the ma...

Drilling process is one of the most important operations in aeronautic industry. It is performed on the wings of the aeroplanes and its main problem lies with the burr generation. At present moment, there is a visual inspection and manual burr elimination task subsequent to the drilling and previous to the riveting to ensure the quality of the product. These operations increase the cost and the...

ABSTRACT: As the representative of manufacturing industry, aircraft assembly lacks of effective method to forecast man-hour. The forecasting accuracy of existing methods is universally pretty low. On the basis of full analysis of aircraft assembly’s feature, this study proposes a forecasting model based on support vector machine (SVM), which is optimized by particle swarm optimization. It can c...

Fretting wear in aluminium alloy AA5754 joined by self-pierce riveting (SPR), a relatively new fastening technique increasingly used in vehicle structures, has been investigated in this paper. Surface damages have been induced when a joint experienced a sinusoidal cyclic tension-tension load. Various degradation zones have been characterised in the contact surfaces between the aluminium sheets,...

Compressed-air tools are of interest by reason of their vibratory action which affects the peripheral circulation of the fingers. Raynaud's syndrome in riveters, pneumatic chisellers and drillers is well known. The harmful effect is almost certainly due to vibration, although cooling of the hands may occur with some pneumatic tools and may be a contributory factor.* Apart from using compressed ...

This paper covers the status on present manufacturing and assembly techniques and trends in new manufacturing technologies for the development of future combat aircraft. Aircraft building involves lot of challenges right from a detail component stage to the sub-assembly and assembly stage because of the complexity involved in the design and manufacturing of aerodynamic contour with weight contr...

This riveting study dives into the dynamics of net interest margin (NIM) within Vietnam’s commercial banking sector from 2007-2018, offering fresh perspectives by considering factors like mergers and foreign ownership ratios. Our findings unveil a positive correlation between NIM variables such as credit risk, risk aversion, loan-to-customer ratio, implicit rate, equity inflation. Conversely, tak...

The design of micromechanical devices that can facilitate large but recoverable deformations requires a mechanical behavior embosoms hyperelasticity. While multiphoton lithography is the epitome microscale fabrication, employed materials demonstrate linear elastic response accompanied by limited ductility. In this study, we investigate how hindrance be circumvented through pantographic structur...
