The jute fiber is one of the strongest lignocellulosic fibers with different applications such as fabrics, ropes as well as engineered composites for automobile parts. In this study, the jute yarns were exposed to different temperatures of the thermal cycles (22°C, 40°C, 80°C, 105°C and 150°C). The mechanical tests were conducted using the 3R Syntax machine and the experimental results depended on different temperatures of thermal cycles were recorded. The mechanical properties of jute yarns decrease with the increase of temperature of the thermal cycles.

“…The jute fibers of different lengths, collected from different parts of the same plant, have different tensile strength. 87 The tensile strengths of banana short-fiber, macro particles and micro particles-based NFRPCs increase; however, the tensile modulus decreases with an increase in the fiber size. 88 The long curaua fiber reinforced epoxy composite possesses the maximum tensile strength.…”

In recent years, researchers and scientists are facing problems in terms of environmental imbalance and global warming owing to numerous use of composite materials prepared by synthetic fibers and petrochemical polymers. Hence, an increasing attention has been devoted to the research and development of polymer composites reinforced with the natural fibers. The natural fibers are the most suitable alternative of synthetic fibers due to their biodegradability, eco-friendliness and acceptable mechanical properties. The natural fibers are attracting the researchers and scientists to exploit their properties by amalgamating them with the polymer. The properties of natural fiber reinforced polymer composites mainly depend upon various factors such as properties of fibers and matrices, fiber loading percentage, size and orientation of fibers, stacking sequences, degree of interfacial bonding, fiber surface treatments, hybridization and incorporation of additives and coupling agents. Tensile and flexural tests are the most important investigations to predict the applications of the materials. A good number of research has been carried out on tensile and flexural properties of natural fiber reinforced polymer composites. In this paper, a review on tensile and flexural properties of natural fiber reinforced polymer composites in terms of effects of fiber weight fraction, geometry, surface treatments, orientations and hybridization is presented. Moreover, recent applications of natural fiber reinforced polymer composites are also presented in this study.

“…Alternatively, one can use possibility distributions or fuzzy numbers (e.g., triangular fuzzy numbers and trapezoidal fuzzy numbers) [ 31 , 32 , 33 , 34 ] to represent the uncertainty associated with each combination of machining condition and performance parameter. Possibility distribution based analysis has been shown to be effective in quantifying the uncertainty associated with materials’ properties [ 35 , 36 , 37 ], surface roughness [ 38 , 39 ], CO2 emissions and alike [ 40 ]. A possibility distribution is a probability-distribution-neutral representation of uncertainty associated with a quantity [ 31 , 32 , 33 , 34 ].…”

Ti6Al4V alloys are difficult-to-cut materials that have extensive applications in the automotive and aerospace industry. A great deal of effort has been made to develop and improve the machining operations of Ti6Al4V alloys. This paper presents an experimental study that systematically analyzes the effects of the machining conditions (ultrasonic power, feed rate, spindle speed, and tool diameter) on the performance parameters (cutting force, tool wear, overcut error, and cylindricity error), while drilling high precision holes on the workpiece made of Ti6Al4V alloys using rotary ultrasonic machining (RUM). Numerical results were obtained by conducting experiments following the design of an experiment procedure. The effects of the machining conditions on each performance parameter have been determined by constructing a set of possibility distributions (i.e., trapezoidal fuzzy numbers) from the experimental data. A possibility distribution is a probability-distribution-neural representation of uncertainty, and is effective in quantifying the uncertainty underlying physical quantities when there is a limited number of data points which is the case here. Lastly, the optimal machining conditions have been identified using these possibility distributions.
