C. Rontescu, T. D. Cicic, C. G. Amza, O. Chivu, Polytechnic University of Bucharest, Romania. D. Dobrotă, Engineering Faculty, University “Constantin Brâncuşi” of Târgu-Jiu, România This paper presents the results obtained following the Finite Element Method (FEM) simulations on a bike frame made of 3 different materials, Al6061, Carbon Fiber and Ti6Al4V, in order to identify the optimum materi...

Metal matrix composites, in particular, Aluminium Matrix Composites are gaining increasing attention for applications in aerospace, defence and automobile industries. The use of nonconventional machining techniques in shaping aluminum metal matrix composites has generated considerable interest as the manufacturing of complicated contours such as dies. Electrical discharge machining (EDM) appear...

Since composite materials were initially used in airplanes a few decades ago, substantial research has been done on problems such as lightning strike protection (LSP) and electromagnetic interference (EMI) shielding. In the current state of technology, aerospace industry needs cutting-edge to meet requirements like lower weight higher values strength stiffness protect against interference. On o...

In this research work, estimation of tool wear for the CBN / PCD tool has been done by using Echostate Neural network during machining of Al6061 metal matrix composite. AN estimation percentage of 90.62% has been achieved.

This study presents the design and stress analysis of mobile robot switchover module (track tensioner), which helps the robot to work in hybrid locomotion mechanism. The track tensioner is a loading and unloading module that helps the locomotion system transformability while robot moves either on wheel or track mechanism. The selection of suitable material for its design, the model is therefore...

Microstructural inhomogeneity generally deteriorates the corrosion resistance of materials due to the galvanic effect and interfacial issues. However, the situation may change for nanostructured materials. This article reports our studies on the corrosion behavior of SiC nanoparticle-reinforced Al6061 matrix composite. It was observed that the corrosion resistance of Al6061 increased when SiC n...

The high cost of fabrication hindered the actual application of metal matrix composite (MMC) despite of their high stiffness, strength, corrosion resistance, wear resistance, non-reactivity with chemicals and so many other tailored quality which are never obtained in alloy of metals. In this study, a modest attempt has been made to find out the process parameters at which best mechanical proper...
