At the other hand, very few literatures are available in view of the ternary blends of polymers with addition of nano-particles. The ternary polymer blends with their rheological and morphological properties are reviewed in this research work. The specific work is concentrated on PP (polypropylene)-PS (polystyrene)-PMMA (Poly (methyl methacrylate)) ternary blends with or without compatibilizer in presence of the MWNT (Multiwall carbon nanotube) nano-particles and improvement in mechanical and thermal properties of the resulting material were studied. In the literature, Impact of the mixing time and dispersed phase content were observed in relation with volume average diameter and volume percentage. Addition of SEBS (Styrene-ethylene-butylene-styrene) to the PP/PS blend decreases stress at breaking point and increases impact strength. SIS (Polystyrene-block-polyisopreneblock-polystyrene), LUC (maleic anhydride Lucofin R 1492M HG) and PODIC ((Peroxan C126), a dimyristylperoxydicarbonate)) are excellent compatibilizers for enhancing impact Strength.

Syntactic foams are used as energy absorption sandwich core for several applications like marine, automotive and aerospace. Properties of syntactic foam can be tailored by addition of filler material. In this work hybrid syntactic foam is fabricated by addition of two types of filler materials that are hollow glass microballoons and fly ash cenosphere into vinyl ester matrix at different concentration. The volume fraction of filler content with respect to matrix is fixed to 50% and composition of two fillers varied. Hybridization of two different types of ceramic microballoons in vinyl ester matrix gives maximum 9.58% improvement in impact strength with respect to plane hollow glass microsphere syntactic foam. Enhancement in flexural strength and Flexural modulus observed is 27.7% and 27.16% respectively as compared to plane hollow glass microsphere syntactic foam.

The HNTs and HNTs modified using PEI filled 90/10 (wt/wt) polypropylene (PP) and acrylonitrile butadiene styrene (ABS) blends and its nanocomposites are prepared by melt mixing technique in presence of dual compatibilizer. Droplet morphology is refined in matrix as well as selective localization of HNTs modified using PEI shows increase in crystallinity of PP phase and formation of β-form of PP crystals. Uniform dispersion of HNTs modified using PEI in PP resulted in improvement in impact strength, tensile modulus and thermal stability. The enhancement in tensile strength, tensile modulus, and impact strength for 1 wt% of HNTs modified using PEI filled 90/10 (wt/wt) PP/ABS blends with dual compatibilizer are 14.9, 20 and 15%, respectively.

Blends of biodiesel are prepared by varying percentage of biodiesel in diesel (B20, B40, B60). Engine input parameters such as compression ratio (13:1, 15:1, 17:1) and load (4, 8, 1.2 kg) are varied to optimize the results. Taguchi method of optimization is used to study the effect of various combinations of input parameters on performance of VCR engine. Analysis of variance (ANOVA) is done to identify significance of individual input parameter on brake power, brake-specific fuel consumption, and exhaust emission. The optimization helps to select optimum values of compression ratio and load that would minimize exhaust emission and brake-specific fuel consumption but also maximize brake power. Engine performance is highly influenced by load.

The parameters considered are water pressure, feed rate, abrasive flow rate and stand-off distance. The experiments were performed on the abrasive water jet machine. The experiments planned, conducted and analysed using Taguchi method. It is found that the MRR is mainly influenced by feed rate; where as other factors have very less effect on material removal rate. Similarly SR at Top and Bottom are measured and analysed. Abrasive Water jet machining (AWJM) is a non-conventional manufacturing process, where material is removed from the work piece by impact erosion of pressurized high velocity water stream mixed with high velocity grit abrasives on a work piece. There are so many process parameters which affect the quality of machined surface cut by AWJM. But, the traverse speed, hydraulic pressure, stand-off distance, abrasive flow rate and type of abrasive are important. However, the important performance measures in AWJM are Material Removal Rate (MRR), Surface Roughness (SR). This work reports influence of process parameters of AWJM in machining AISI D3 material. It was confirmed that optimal combination of AWJM process parameters satisfy the real need for machining of AISI D3 in actual practice.

The use of nanofillers to enhance certain properties (e.g., mechanical, chemical, thermal, etc.) of a polymer mixture, as well as to stabilize and modify the blend morphology, has sparked a lot of interest in nanocomposites with multiphase matrices. In this review, recent breakthroughs in polyamide (PA), acrylonitrile-butadienestyrene (ABS), and polypropylene (PP) blend-based nanocomposites are studied. Polyamide 6 (PA6) (rich) blend-based nanocomposites made by blending various thermoplastics with nanofillers are highlighted. The production and characteristics of nanocomposites containing nanofillers made from a PA blend are described. A survey revealed that the volume and size percentage of the nano-filling materials affect wear resistance and friction coefficient. Multi-functional fillers can also be used to create composite materials with high performance that cannot be obtained with a single filler.

Polyamide 6 (PA6) (rich) blend-based nanocomposites made by blending various thermoplastics with nanofillers are highlighted. The production and characteristics of nanocomposites containing nanofillers made from a PA blend are described. A survey revealed that the volume and size percentage of the nano-filling materials affect wear resistance and friction coefficient. Multi-functional fillers can also be used to create composite materials with high performance that cannot be obtained with a single filler.

Transportation sector contributes major part of economy development. Fossil fuels like Petrol and Diesel are used for transportation and heavy duty vehicles. Higher rate of consumption of these naturally available fuels leads to its depletion and deterioration of environment. To solve such issue many researchers are interested in identifying and using alternative fuels for internal combustion engines. Biodiesel is renewable fuel and can be used as alternative fuel for Diesel engines. In present work Canola oil based Biodiesel (COB) is blended in Diesel with different concentration like B20, B40 and B60. Engine input variables like compression ratio (13:1, 15:1, 17:1) and load (4, 8,12kg) are considered to optimize the results. The Performance of Variable Compression Ratio (VCR) Diesel Engine is evaluated using Taguchi method. Analysis of variance is conducted to recognise the significance of input variables on Brake Thermal Efficiency, Brake power Specific Fuel Consumption. Results of optimization showed that load is the most crucial factor which affects the engine performance i.e. Increase in load decrease the Brake Thermal Efficiency, Brake Power and increases the Specific Fuel Consumption.

Syntactic foam has unique properties of high strength at low density thus these become widely used in subsea buoyancy applications. For several applications like marine, automotive and aerospace, syntactic foams are used as energy absorption sandwich core. The current study is focused to take a look of the work done in the area of characterization of Syntactic Foam composite materials and various modifications in synthetic foam. This study is attempt to take overview of different constituent materials used to make polymer composites, failure mechanism and manufacturing process of Syntactic Foam composite material. The behavior of such hybrid syntactic foam under tensile loading, compression loading, flexural loading and impact loading are the main areas of interest of researchers. This paper reviews work related to syntactic foam fabricated by using following two types of micro balloons that are hollow glass microspheres and fly ash cenospheres.
