Tribological properties are one of the important parameters of examining the performance of the diesel oil. Diesel oil is predominantly used everywhere and it is one of the important essentials in daily living. This study aims to examine the tribological and the thermo physical properties of molybdenum disulfide nano particles. In this work the nano particles were dispersed in 3 different concentrations such as 0.3, 0.5 and 0.7 weight percentages with the pure diesel oil. Molybdenum disulfide nano particles were immersed in diesel oil at different proportions. In this work a pin on disc tribometer were utilised to analyze the frictional properties. Wear properties of Molybdenum disulfide (MoS2) nano particles were analysed. The results reveal that the addition of molybdenum nano particles marginally reduced the wear properties. The other key properties such as nano fluids viscosity, viscosity index obtained the highest values at 0.7 weight percentages. Based on the results it was concluded that the frictional property had no impact on the anti friction and anti wear properties at different concentrations with diesel oil.

The results exhibit that the mixture of 60%VER and 40%PU blend shown the improved impact strength as well as max. elongation during break. Whereas slight drop in mechanical strength in all tests were noticed. The scanning electron microscope analysis as well as performed on the reinforced and unreinforced composite.

Copper plays a vital role in the performance of brake friction materials due to its better thermal conductivity and fade resistance. But owing to the negative impact towards to the aquatic life, the usage of copper in brake material formulations is reduced considerably in developed nations. Research is being carried out globally to reduce the copper with single ingredient or combination in brake materials. Thus the present study dealt with the development of brake pads using a commercially available alloy of aluminum and iron (Mechanomade) in the formulation with other ingredients. To compare the performance, three other brake pads were also developed by replacing mechanomade with copper, aluminum, and iron in the formulation. The developed brake pads were analysed for the physical, chemical, mechanical and thermal properties as per standard industrial practice. The tribological characteristics were analysed using Chase test following SAE J661. It was evident from the test results that Iron aluminum alloy based brake pads showed good fade and recovery characteristics. To study in detail regarding the worn surface characteristics, Scanning Electron Microscope with Elemental mapping was used.

The Identification of new polymeric fibers is in high demand owing to its versatile applications. In this work the Lightweight foamed concrete (LFC) concrete is selected as a key ingredients and it is blended uniformly. In this work various mechanical properties were examined by incorporating newly modified polypropylene fibers, it is biaxial oriented in its structure.4:1 ratio of sand proportion is maintained. Newly modified PP fibers with percentages of 0.30% and 0.40% were added. The foamed concrete was intended to accomplish the consequence of impact from volume newly modified polypropylene fiber utilized with various relieving ages. The examination was setup to look at its mechanical properties with agreement to ASTM standard strategy for testing. From the outcome broke down, the consideration of polypropylene fiber into the lightweight foamed concrete examples has more commitment in flexural quality when contrasted with control test without the fiber. The 0.30% and 0.40% level of polypropylene fibers added is demonstrated to have contributed more on flexural of LFC. Based on the results it was concluded that the 0.30% is an ideal volume of fibers that ought to be incorporated to contribute the greatest flexural quality of the lightweight foamed concrete.

This research paper presents a unique biodiesel, Bael biodiesel, with diesel vehicles. Bael oil is produced from bael seeds, which are obtained from the fruits of the bael tree. Within that article, the performance, toxicity, and ignition properties of a diesel engine running on diesel, bael seed oil methyl ester (BSOME) and its blends (B20, B40, B60, B80, and B100) are discussed. Due to the increased acid quality of the oil, BSOME was constructed by mixing bael seed oil and methanol in an acid as well as alkali catalytic process. While BSOME as well as its blends have poorer brake thermal efficiency than diesel, they have smaller emissions, with the exception of NOx. According to this research, blend B20 (20% bael biodiesel + 80% diesel) can be used to partly replace diesel in conventional CI engines despite imposing some modifications.

The intent of this work is to investigate the mechanical properties of chemically treated banana and areca fibers as reinforcement for various applications. Compression molding technique was used to prepare the composites. Fiber loading was varied by 5 and 10 volume weight percentages. Both areca and banana fiber were chemically treated with 5 wt.% sodium carbonate. Tensile, flexural and hardness Testes were carried out. On seeing the results, it was witnessed that the mechanical properties and thermal stability got increased with fiber loading and sodium carbonate treatment. Ten fibers reinforced composite provided the best set of mechanical and thermal properties, while banana fiber reinforced polypropylene composites had slightly better properties as compared to jute fiber reinforced polypropylene composites.

Lubrication and abrasiveness in the brake friction composites are imperative characteristics for the better tribological performance at elevated temperature conditions. The present study aims to develop brake friction composites by conventional manufacturing processes in the form of standard brake pads using iron sulfide as a solid lubricant with a synergistic effect of red mud as an abrasive. Three different brake friction composites were developed by varying key ingredients such as red mud and iron sulfide by keeping other parental ingredients as constant. The developed composites were subjected to experimentation for physical, chemical, mechanical and thermal properties in accordance with industrial standards. The tribological performance was analyzed experimentally using Chase friction test rig according to IS2742 part-4. From the experimental work, it can be concluded that the synergetic effect of red mud and iron sulfide particles in friction composites showed stable fade and recovery behaviors, while the iron sulfide-based friction composites showed lesser wear rate. Scanning electron microscopy (SEM) of the Chase tested friction composites showed the surface characteristics of the composites.

The manuscript discusses about the effect of compressive load on the E-Glass fiber reinforced interpenetrating polymer networks (IPNs). In this work, a series of combination of vinyl ester (VER) loaded polyurethane (PU) IPNs have been taken as the matrix material with the E-Glass reinforcement, with the loading of 0%, 10%, 20%, 30%, 40%, 50% PU respectively. Besides hand-layup technique was used to fabricate the cylindrical shells in order to get the final shape of the IPN composite pipe. Simultaneously to validate the compressive strength behavior of the IPN composite pipe, experimental analysis was carried out as per the ASTM D695 standard at normal room temperature to extract compressive strength value of the PU loaded IPN composite pipes. During this test, it was observed that physical strength of the composite pipes reduces gradually as much as PU addition into the IPN composite pipe increases. Surprisingly, another important notification was that, the geometric structure of the composite pipes is not affected as like as the crushing observed on the pure VER pipe. As much as loading of the PU into the IPN, increases the structural integrity of the composite pipes in outstanding (retains structural ability) manner. Further the experimental analysis values are validated with numerical analysis software ANSYS, obtained values and numerical values are shown good agreement each other.

The Purpose of this work is to develop a niobium based metal matrix alloy through sintering based powder metallurgy technique. The 2, 4 and 6 weight percentage of Titanium Carbide (TiC) is added to the alloy. Various material properties such as hardness, tensile strength, impact strength and density are measured after the addition of TiC particle. The characterization, microstructure and particle size of the developed metal matrix are learnt through Scanning Electron Microscope (SEM) and Energy Dispersive Analysis of x-rays (EDAX). Finally, the synthesized niobium metal matrix is machined by unconventional machining processes namely Ultrasonic Machining (USM) and Laser Beam Machining (LBM) processes. The various input and output parameters have been considered for this experimental work. The most influential parameters on Material Removal Rate (MRR) and Surface Roughness (SR) are found by Analysis of variance. The systematic evaluation of optimal parameters of MRR and SR are carried out by using taguchi approach.
