The effects of water absorption on the mechanical properties of Roselle Fiber/Coconut ShellParticulate/Vinyl Ester (RF/CSP/VE) hybrid composite were studied in this paper, based on the content of Roselle Fiber (RF) and Coconut Shell Particulate (CSP). The RF/CSP/VE hybrid composites were prepared on dry basis and their mechanical properties are evaluated for comparison with the mechanical properties of RF/CSP/VE hybrid composite at wet condition. The CSPs are added with RFs at four different concentrations (0, 5, 10 and 15% by weight) at dry condition. The content of Roselle fiber is fixed as 20 wt%. Composites are prepared by hand lay-up technique. It was observed that the tensile and flexural properties of RF/VE composite at dry condition are increased linearly with the increase of CSP content. The impact strength of RF/VE composite at dry condition is not significantly affected by the addition of CSPs. The percentage of water absorption of RF/VE composite was decreased with the addition of CSP content. The highest and lowest percentage of water absorption was identified at 20RF/5CSP and 20RF/15CSP composites respectively. Mechanical properties of RF/VE and RF/CSP/VE composites at dry condition are higher than the mechanical properties of RF/VE and RF/CSP/VE composites at wet condition.The effects of water absorption on the mechanical properties of Roselle Fiber/Coconut ShellParticulate/Vinyl Ester (RF/CSP/VE) hybrid composite were studied in this paper, based on the content of Roselle Fiber (RF) and Coconut Shell Particulate (CSP).

In current days, refrigeration frameworks are basic for modern and household applications. The refrigeration frameworks have been examined altogether from various perspectives to decrease the power utilization. This investigation manages Experimental examination of a vapor pressure refrigeration framework by utilizing nano refrigerant (R290/R600a/Al2O3) to improve the framework execution and decrease the power utilization. In this examination, the framework execution was researched utilizing vitality utilization test. The outcomes demonstrate that by including the nano particles (Al2O3) to the other refrigerant blend (R290/R600a) the Coefficient of execution is somewhat expanded while control utilization by blower is marginally diminished. The nano refrigerant (R290/R600a/ Al2O3) can work ordinarily and proficiently in coolers. Contrasted and icebox with unadulterated (R290/R600a) as working liquids, 0.3 g/L convergences of (R290/R600a/ Al2O3)can spare 29.33% vitality utilization. Henceforth, the residential cooler execution will be improved by including the nano particles (Al2O3) to other refrigerant blend (R290/R600a).

The paper is about tribological wear behaviour of composite of Aluminium 6063 alloy with Silicon Carbide and Granite. Since the wear resistance of aluminium 6063 is comparatively low, we are going to increase the wear of aluminium 6063 by adding silicon carbide to it. The silicon carbide will not mix with aluminium 6063 completely, we are in need of another material to blend that two material. For that purpose we are using granite. It will also increase the strength of the composite material. We are going to make three different composite material which varies in their composition. The compositions of aluminium 6063 are 95%, 93%, 91%. The composition of Silicon Carbide is made constant as 3% and Granite have 2%, 4%, 6% respectively. In our project we casting three rods each of one Kg. The weightage of Aluminium 6063 alloy will be 950, 930, 910 grams. The weightage of Silicon carbide for all three composition will be 30 grams. The weightage of Granite will be 20, 40, 60 grams.The paper is about tribological wear behaviour of composite of Aluminium 6063 alloy with Silicon Carbide and Granite.

The current experimental toil is embraced to investigate the thermal conduct of short glass fiber (SGF) fortified thermoplastic copolyester elastomer (TCE) hybrid composites loaded up with both micro (short carbon fibers, PTFE, SiC, Al2O3 and MoS2) and nano (Al2O3 and PFPE) sized ceramic particulate fillers. The composite test coupons are produced by compounding in twin screw extruder followed by injection molding. The readied hybrid composites are evaluated for thermal conduct in thermal gravimetric analysis (TGA). The outcomes uncovered that the TCE and their composites displayed the degradation in three phases. The degradation temperature of the composite expanded with the expansion in fiber and filler content. Notwithstanding, softening temperature of the TCE composites did not modified impressively within the sight of fiber and fillers.

Incremental Forming process is a flexible and versatile process with a promising future in batch manufacturing and prototyping sectors. Traditional sheet metal forming processes usually involve high costs due to the design and manufacturing processes involved in it, more over the design of die is unique for every individual component. The contemporary sheet metal industry employs forming methods which uses precise punch and dies to form components with precise tolerances. In mass production the high cost involved in the manufacture of dies and punches are absorbed by the number of components formed, whereas this is not the case for low volume production which increases the manufacturing cost of products in low volume production. To solve this, Incremental forming process - a rapid sheet metal forming process has been introduced and is under research for couple of decades. This process still need to be improved in accepts of accuracy and product quality. ISF process needs the following in most of the cases: a simple tool, a fixture for holding sheet material and a universal Computer Controlled Machine (CNC) machine. This paper aim to describe the current status of incremental forming techniques in terms of input process parameters and their influences, formability limit, accuracy, surface finish and the current trend research directions.

Natural fiber composites have attracted significant response in the field of structural mechanics for more than a decade since they hold varieties of desirable advantages. They exhibit comparably minimal amount of pollution effect to the environment. Because of being with great strength to weight ratio, different kind of research works with different kind of natural fibers have been made by the researchers for many specific application areas. In the proposed work, sisal and banana natural fibers have been hybridized with the distributing medium of epoxy resin under three different combinations to form the composite structures. Mechanical strength analyses were performed on the proposed composite specimens such as tensile strength and flexural strength tests. Numerical analyses have also been made for ensuring the experimental results. Grey Relational Analysis has been performed with the results of the two mechanical strength tests to identify the best combination among the three which yields good mechanical property under all tensile and flexural loading conditions.Natural fiber composites have attracted significant response in the field of structural mechanics for more than a decade since they hold varieties of desirable advantages.

Thermal energy storage becomes a greater challenge in thermal conversion systems such as solar thermal systems. The energy demand and supply may not be matched at the most point of time, hence requires efficient thermal energy storage. Candle Making Wax (CMW) is one among the potential material to store energy by means of changing its phase. Still, they are suffering with poor thermal conductivity. This paper addresses this problem by diffusing a suitable nanoparticle in CMW. Nano-TiO2 particles have been used as enhancer in CMW in different proportions viz., 0 vol.%, 0.5 vol.%, 1.0 vol.%, 1.5 vol.% and 2.0 vol.%. These five samples were inspected using Fourier Transform Infrared Spectrometer (FT-IR) to verify their chemical stability. Thermal conductivity of all the samples were initially calculated using different analytical models and later, they were experimentally determined with the help of thermal properties analyzer. The results proved that the thermal conductivity can be improved substantially by dissolving the nano-TiO2 in CMW. Thermal conductivity escalates with the increased vol.% of nanoparticles. However, values predicted through the analytical models showed the linear improvement, whereas the experimental values were not exactly linear and their slope becomes less at the higher vol.% of nanoparticles. It was observed that the solid state thermal conductivity was more compared to their liquid state, Also, it was noticed that the experimentally measured values were relatively higher than the values obtained through the analytical models and variation was high at higher vol.% of nanoparticles.Thermal energy storage becomes a greater challenge in thermal conversion systems such as solar thermal systems.

Aluminium 5052 have its various applications in aerospace, fencing, hydraulic tubes and marine components due to their high dimensional stability, light in weight, high strength to weight ratio, economic and elevated stiffness. Since Aluminium alloy (Al 5052) has its application in aerospace and marine industries, its wear properties have to be improved further for better life of the components in its applications. Literature study reveals that studies were not carried out for Al 5052 alloy for improving its wear behaviour. Tungsten carbide (WC) normally used for manufacturing wear-resistant tools, cutting tools, protective coatings and carbide steel because of its wear resistance properties. In this research the wear behaviour of Al 5052 alloy analysed by reinforcing with varying weight percentage of tungsten carbide (1%, 3 %, 5%) fabricated using stir casting process. Taguchi L27 orthogonal array were used to conduct the experiment. Dry sliding wear behaviour is performed by means of Pin-on-disc wear testing apparatus. The process parameters are composition, Speed, Load, Sliding distance and the responses are Coefficient of Friction (CoF) and specific wear rate. Taguchi Signal-to-Noise ratio was carried out to determine best optimal combination to minimize the Coefficient of Friction (CoF) and specific wear rate. From the result it is seen that 5% of tungsten carbide reinforcement gives lower Coefficient of Friction (CoF) and specific wear rate at various parametric condition. To identify the wear track Scanning Electron Microscopic analysis were made and it is analysed that the lesser wear is seen in Al5052 reinforced with 5% of tungsten carbide with constant input parameter. From experiment, the Tungsten carbide improves wear resistance property of Al 5052 alloy with the increase in weight percentage of reinforcement.Aluminium 5052 have its various applications in aerospace, fencing, hydraulic tubes and marine components due to their high dimensional stability, light in weight, high strength to weight ratio, economic and elevated stiffness.
