behavior of phenol formaldehyde used un-cured and chemically
(5% and 10%) cured wood polymer composites under
different ratios. The wood flour with PF resin thoroughly
mixed with by using rotary barrel type whizzer according
to calculated volume proportions. The thermal behavior
of these WPCs showed that the thermic stability slightly
increases with inclusion of wood flour content. The characteristics
of raw material and mixing ratios contribute a
prominent part in the thermal properties of fabricated samples
of wood polymer composites. The limit for temperature
should be 250 °C for practical applications. The two way
ANOVA is used to optimize the experimental results.

(cns) reinforced hybrid composites consisting of a varying
quantities of pistachio nano-particles (0–4% [incremental
of 1%]) were fabricated and eventually estimated for
mechanical and sliding wear characteristics. Density of these
hybrid composites was directly proportional to proportion of
additives added, whereas porosity was found to be declining
with the increase of pistachio nano-particles. Composites
with 2% pistachio nano-particles and 15% coconut and
wood apple shells powders each had superior tensile and
compressive qualities than different configurations. Dry
sliding wear evaluations of the composed composites
were performed at normal temperature in a pin-on-disc
equipment with varying speeds, distances, and different
loading conditions. Pistachio nano-particles offer the
eminence resistance to the wear, with a contribution ratio of
32.61%, and a hybrid composites with combination of 2 wt%
pistachio nano-particles, 10 n normal load, 1.5 m/s sliding
speed, and 500 m sliding distance resulted in greater wear
resistance as compared to all other category of composites
prepared.

and an increasing population. It takes several years for solid trash, such as plastic bottles and supermarket bags, to decompose in nature. In addition, plastic disposal techniques such as landfilling,
reuse, and incineration pose significant threats to human health and the environment. In this paper,
we investigated whether the impact of mixing biodiesel with waste oil from recycled plastic on the
resulting fuel mixture’s yields better physical and chemical properties . Consequently, pyrolysis is
one of the most advantageous and practical waste disposal methods as it is both environmentally
benign and efficient. Pyrolysis is the high-temperature thermal breakdown of solid waste to produce
pyrolytic oil. The pyrolytic (plastic) oil produced is converted to a hydrocarbon-rich pyrolytic fuel.
Similar to diesel and gasoline, pyrolytic fuel has the same calorific value. Internal combustion engines
may operate on pyrolytic fuel without suffering a performance reduction. Researchers examined
engine performance and exhaust pollutants. The research discovered that the engine could operate
on plastic pyrolysis fuel at full load, enhance brake thermal efficiency by 6–8%, and lower UBHC
and CO emissions; however, nitrous oxide (NOx) emissions were noticeably higher. The findings
demonstrated the possibility of using plastic pyrolysis fuel as a diesel substitute.

Among various discontinuous dispersoids used, fly ash is one of the most inexpensive and low density reinforcement available in large quantities as solid waste by product during combustion of coal in thermal power plants. E-glass is another reinforcement used in this composite to enhance some of the mechanical properties of Al-2024. It is therefore expected that the incorporation of E-glass and fly ash particles in aluminium alloy will promote yet another use of this low-cost and moderate strength by stir casting method. The present investigation has been focused on the tribological properties and parameters are optimized by Taguchi method. Finally it is also validating and analysed by ANOVA.

The purpose of the current Paper is therefore aimed at highlighting the focus of the current research scenario, in the field aluminium based hybrid composites, to explore the materials for automotive and aerospace applications; this is achieved with the help of stir casting technique. Stir casting is one of the novel methods to produce metal matrix composites with more uniform distribution of matrix and reinforcement constituents. This approach involves mechanical mixing of the reinforcement particulates/particles into a molten metal bath. A crucible is heated to malt aluminum metal, with a motor and blades is placed in the crucible that helps to get uniform molten metal. The reinforcement is poured into the crucible above the melt surface and at a controlled rate, to ensure a smooth and continuous feed. As the blades rotate at moderate speeds, it generates a uniform mixing of the reinforcement particles into the melts to produce homogenous composites. In this paper we discussed about construction and experimentation of stir casting setup for metal matrix composites.

Wear, hardness and compressive tests are conducted and compared with each other, sliding wear test carried out on pin on disc apparatus with constant speed and time but varying loads. Compressive test carried out in universal testing machine (UTM) for heat treated and non heat treated samples for obtaining compressive strength and it will be compared each other. Brinell and Rockwell hardness are carried out in hardness apparatus. It includes depth of indentation on surface of samples in different positions by using formula of BHN the hardness of the sample is calculated. In case of Rockwell hardness test direct reading from testing apparatus obtained but it includes different scales with having standard loads for example in this thesis B scale used which having load of 100kg. Hence by applying load in different positions on surface of sample and averaging of these readings will give the RHN value. The best results are obtained by heat treated samples compare with un heat treated samples.

Obtaining good properties with aluminium as ductile matrix blended with different reinforcement. Generally most common methods for producing this type of metal matrix composites is powder metallurgy since it has many variations and also is relatively low-cost method. A lot of different techniques of compacting aluminium alloy powders have been previously investigated. Among those techniques equal channel angular pressing and powder metallurgy etc. Equal-channel angular pressing (ECAP) is an effective fabrication process for obtaining ultrafine-grained materials. This paper emphasis on aluminum alloy composite processed by ECAP with different passes at room temperature. The factors influencing the mechanical characters are observed, including the die corner angle within the ECAP die and the number of imposed passes. It is shown that good properties may be achieved through ECAP processing when the number of passes in ECAP is reasonably high.(ECAP) stands out due to its beneficial influence on the main problem that arises during powder compaction and that is a non-uniform distribution of reinforcement particles. This paper gives an overview on ECAP method principles, advantages and produced powder composite properties.
