“…Nanopowder was made by US Research Nanomaterials, Inc. Due to its high thermal conductivity, excellent wear resistance, a smaller thermal expansion coefficient, chemical resistance, comparatively high strength, low coefficient of thermal expansion and availability, the SiC particle as reinforcement is widely used in the metal base composite. Microhardness of SiC is 2840-3320 kg/mm 2 , and it is a semiconductor and resistant to oxidation in high temperature [22][23][24]. Also, the addition of silicon particles in the matrix will significantly improve the mechanical properties and thermal properties of the metal [25].…”

The aim of this study is to investigate the tool wear on friction stir processing of Al7075 base nanocomposite. The silicon carbide nanopowder was used as a reinforcing phase. The effects of input parameters including rotation speed, traverse speed and the pass number on the tool wear, microhardness and the topography were studied through the response surface methodology. Each of the input process parameters was selected in five levels, and other parameters were considered constant. The friction stir tools were examined under a scanning electron microscope, and wear mechanisms were investigated at different conditions. The analysis of variance revealed that quadratic polynomial models are fitting to predict tool wear and microhardness. In addition, the results showed that tool wear also varied between 12 and 116 mm under different parameters. Furthermore, the rotation speed and pass number of 52.9% and 13.1%, respectively, have the greatest impact on tool wear. Traverse speed with more than 55% had the most effect on microhardness comparatively. Also, energy-dispersive spectroscopy analysis showed that with the highest percentage of Fe in rotation speed 900 rpm, traverse speed 50 mm/min and with three passes, the microhardness reached the highest level of 127.24 Vickers.

“…Equipment made from composite materials are used in the manufacturing industries for wide range of applications [1,7,8,9,10,11,12,13,14]. They can operate in various temperature ranges, where variations in temperature with time can give rise to the development of thermal stresses at microstructural levels, which can decrease the strength of the material [2].…”

“…They can operate in various temperature ranges, where variations in temperature with time can give rise to the development of thermal stresses at microstructural levels, which can decrease the strength of the material [2]. Carbon fiber reinforced polymer (CFRP) is commonly used in engineering applications which require high strength-to-weight ratio and low thermal expansion [8]. An issue associated with this type of composite material is the non-uniformity in the microstructural element distribution, which may become a possible cause of thermal stress concentration leading to failure along the material interface.…”

“…Liu et al [25] studied through numerical simulation the stress distribution created by compressing carbon fiber/epoxy braided composite materials. Hassanzadeh-Aghdam et al [8] furthered this study by considering both thermal elastic-plastic behaviour of a nanocomposite reinforced with SiC nanoparticles using micromechanical cell method approach, however the effect of elevated heat intensity was not studied. The literature review on CFRP reveals that the structural integrity of this composite is strongly influenced by any temperature rise.…”

Thermal stress development in materials could lead to structural failure in engineering applications. Carbon-fiber reinforced polymer composite (CFRP) have gained wide acceptance in the manufacturing industry. However, its thermo-elastic behaviour at elevated temperatures still remains an open question. Heat transfer analysis coupled with material layer-wise arrangement technique of the CFRP was implemented to investigate the thermo-elastic behaviour of these composites. A finite element model (FEM) was built and studied using COMSOL Multiphysics software. The heat energy applied in the simulation was sourced from a heat beam model. The deposited beam power was varied from 10 to 200W, and focused at the centre of the laminate (y p ¼ 0.15 m). The laminates considered were made up of six layers with distinctly different stacking sequences. The thermal stresses and strains obtained from the finite element analysis were assessed to observe the material's behaviour when subjected to increasing thermal load. Results revealed that thermal stresses are intense along fiber-direction of the composite laminates. The CFRP material was found to give good thermo-elastic characteristics at lower deposited heat power, however, this was not the case for higher deposited heat power (e.g. 200 W). The anisotropic property of the laminate had a significant influence in managing the thermal stresses. The study was repeated for carbon fibers doped with nanoparticles of silicon carbide (CFSiC) and resin bonded glass fiber (RBGF). It was found that the results were distinctly different when compared with the CFRP laminate. CFSiC showed to exhibit an ehanced thermo-elastic behaviour, due to the high thermal stability of SiC nanoparticles in the composite.
