... However, they emphasized that both filling materials had a positive effect on the wear resistance of the composite. Abdalrazaq et al. 11 investigated the wear behavior of both glass fiber reinforced epoxy composites at different ratios and glass fiber composites with three different filling materials (granite, perlite, CaCO 3 ) at different ratios. They determined wear rates by applying different loads, sliding distance and sliding time. ...
In this study, adhesive wear of woven E-Glass fabric reinforced composites filled with aramid, B 4 C and mica particles at 0.5% wt. and 1.5% wt. ratios were carried out under dry sliding conditions. The effects of filler type, applied loads (5, 10 and 15 N) and sliding distances (250, 500 and 750 m) on the tribological behavior of the composites were investigated on the pin-on-disc device. As a result of the studies, it was determined that the friction coefficient in aramid reinforced composites was lower than the other reinforced composites. In wear volume due to wear, it was observed that the aramid wear volume was less. In addition, Wear volume increased with increasing load for all particle reinforcements. But, the highest wear volume occurred in the neat wear sample at 15 N load conditions. For the wear rate and wear volume, the fillers have shown improvement up to 1.5% wt. in the composite. 1.5% wt. aramid-filled glass fiber woven composites showed the lowest wear rate: 2.82 × 10 ⁻⁴ mm ³ /N-m (at 15 N normal load). In addition, in the scanning electron microscope images taken, it was observed that there were breaks in the size of 15.07 µm in the epoxy and 61.11 µm in the fibers. The use of aramid with particle reinforcement rather than fiber is important for wear. In addition, the lowest wear volume was 65% more resistant at 1.5% wt aramid reinforcement and at 15 N load compared to the unreinforced composite in the abrasion tests.
... These hard particles were responsible for the increment in the dislocation pile up and there was a restriction to the plastic flow.

However, at 75% (v/v) concentration the extraction efficiency was similar to that with the pure methanol, that is, 93.53 mg GAE/g and 23.67 mg TAE/g against 94.42 mg GAE/g and 24.06 mg TAE/g, respectively. Since the solubility of phenolic compounds was improved because of methanol, desorption of solute has become easier due to the presence of water [29], and such extraction efficiency could be expected. Hence, 75% (v/v) methanol was used for next experiments. ...

Fixture design is the most critical aspect for the success of friction stir welding and processing (FSW/P). Nowadays, the machines that developed exclusively dedicated to FSW/P are very expensive, which motivated to design a new innovative fixture. This paper aims to design and develop a robust fixture that can be easy to use on a conventional vertical milling machine. The designed fixture and clamping devices rigidly hold the workpiece in such a way that it restricts lateral and longitudinal movement during processing. The later part carried out a detailed finite element analysis to check the robustness of fixture using Autodesk Fusion 360 software (Education license) and validated it in the actual condition. The fixture setup is installed and tested successfully on the universal vertical milling machine. The result shows that it withstands high forces generated due to relative motion between the tool and the workpiece.

[6] studied the effect of different types of ceramics fillers (granite, perlite, CaCO3) on wear characteristics of glass fiber epoxy composite, and reported that the wear loss of the reinforced epoxy increases by increasing the load, time and siding distance, the adding of ceramics particles to glass epoxy composite increased the wear resistance more than glass epoxy composite without ceramics particles. ...
... Wear test was done according to ASTM G-99 [10] for cylindrical specimens with 10 mm for both diameter and height as shown in figure 2, and performed by using pin on disk tribometer type DUCOM (Wear and Friction Monitor ED-201) of Indian origin as shown in figure 3, in mechanical department laboratories in Tikrit University of Iraq.

Polymeric composite materials have emerged as one of the best composites used in modern and advanced applications due to the important and useful properties such as lightweight, excellent thermal and electrical insulation as well as relatively good resistance. In this paper, a composite material has been manufactured with polymer matrix which is reinforced with ceramic particles and the mechanical properties have been studied. Epoxy resin Quick mast 105 has been mixed with a hardener by a ratio 3:1, then reinforced with different volume fractions of Yttrium oxides Y2O3 (0, 1.5, 3, 4.5, 6%). The composites samples are manufactured with hand lay-up molding, then the mechanical properties such as hardness, compressive strength, flexural strength and the wear rates with different loads (5, 10, 15, 20) Newton are investigated. The results showed that both hardness and compressive strength were increased by increasing the content of the reinforcement as it increased by 62% and 12% respectively, in contrast to flexural strength which decreased by increasing the Y2O3 content by 45%, the wear results showed a decrease in the wear rate by increasing the Y2O3 content up to 3% and then the wear rate is proportional with the reinforcement content and 0% recorded the highest wear rate, on the other hand by increasing the load of the wear rate test, it was found that the wear rate increased at all the ratios of reinforcement.
Friction and wear are identified as huge problems for the engineering industries, and these are being studied extensively in the 21st century with an intension to reduce the wear losses by developing newer and cheaper tribo-materials. Based on this, the current research is based on a novel idea of developing polyester-based wear resistant composites (Cs) filled with a low-cost solid industrial waste produced during the processing of marble rocks. Polyester Cs consisting of three different proportions (0, 16 and 32 wt%) of waste marble dusts (MD) are fabricated and their dry-sliding wear response is evaluated following L30 model of response surface method (RSM) as per ASTM G99-05. The analysis of test result revealed that the Cs wear rate (WR) is affected significantly by the factors like filler content (FC) and sliding velocity (SV) but marginal effect of normal load (NL) and sliding distance (SD) is noticed. Micrographs of the damaged Cs surfaces are studied using a scanning electron microscope (SEM) to get an insight in to the wear mechanism. Two models working on RSM and fuzzy logic (FL) are proposed to determine the effects of significant control factors on the WR more precisely. This research opens up a new arena for rewarding utilization of waste MD in making of Cs with immense potential for industry use such as in tribological applications.
Different materials had been used for sink fabrication in recent years. In this study ceramic filled polyester composite
material has been developed by adding micro-fine limestone and clay ceramic particulates with particle size of <134 μm
to unsaturated polyester resin with a loading weight of 20% limestone and 30% limestone/clay and fixed amount of catalyst
o
(1% weight). The reaction temperature lies within 95.8 – 150 C. Resin Transfer Molding (RTM) technique has been used to
fabricate a prototype sink using wooden and Plaster of Paris (POP) mold with a view to examine surface finish. The prototype
sink produced shows durability with smooth surface finish and can be customized to satisfy end user's preference and
choice.
Organic Rankine Cycle (ORC) system can generate electric energy by running at low temperatures. It is an alternative way of environmentally friendly, safe and cheap electric energy production. As a heat source which can be inducted to the system by a waste heat of any kind of industrial processes, solar energy etc. Therefore, recently range of application has been increasing widely speed in waste heat recovery facilities, or geothermal facilities and for electric energy production in residence. On the other hand, global climate change is one of the vital problems for a healthy world future. As it affects all sectors, maritime transportation is affected by means of precautions to prevent causes of climate change as well. Correspondingly energy efficiency in ship operations has developed as an innovative solution in recent years. Because, ships consume plenty amount of energy while both navigating and berthing in port. In order to minimize environmental pollution caused by ships, usage of renewable energy sources is important. Supporting ships from a port facility energy source is called Onshore Power Supply (OPS). For this purpose, usage of ORC systems that can run with solar energy in ports as OPS is proposed in this paper.
