A comprehensive review of techniques for natural fibers as reinforcement in composites: Preparation, processing and characterization.

The increase in awareness of the damage caused by synthetic materials on the environment has led to the development of eco-friendly materials. The researchers have shown a lot of interest in developing such materials which can replace the synthetic materials. As a result, there is an increase in demand for commercial use of the natural fiber-based composites in recent years for various industrial sectors. Natural fibers are sustainable materials which are easily available in nature and have advantages like low-cost, lightweight, renewability, biodegradability and high specific properties. The sustainability of the natural fiber-based composite materials has led to upsurge its applications in various manufacturing sectors. In this paper, we have reviewed the different sources of natural fibers, their properties, modification of natural fibers, the effect of treatments on natural fibers, etc. We also summarize the major applications of natural fibers and their effective use as reinforcement for polymer composite materials.

Alternative fuels for diesel engines have become vital due to increase in energy expenditure, stringent norms of emission, depletion of fossil fuels and fluctuating cost of the petroleum products in india. To overcfome this problem, it is very important to find alternative fuels. The main focus of this review is to shed light on the importance of tyre pyrolysis oil as an alternative fuel for diesel engines. In this context, tyre pyrolysis oil has recently been receiving renewed interest. In this review, the pyrolysis mechanism, pyrolysis reactors, their product yield, characteristic analysis of tyre such as proximate analysis, elemental analysis and pyrolysis process are discussed. Pyrolysis of scrap tyre starts at 250 °C and gets completed at 550 °C. The presence of a catalyst produces lighter oil with drastic increase in the concentration of single ring aromatics. Engine performance, emissions and combustion parameters, such as the heat release rate and maximum rate of pressure rise, when engines are operated on a tyre pyrolysis oil were also discussed. NO(x), HC, CO, and smoke emissions were found to be higher at higher loads due to the high aromatic content and longer ignition delay. The ignition delays were longer than those with DF. It is concluded that it is possible to use tyre pyrolysis oil in diesel engines as an alternate fuel.
