The extensive use of composites materials has created disposal and environmental issues. With awareness of preserving the environment, the use of environmentally friendly, sustainable and biodegradable composites have been started. From few decades, natural fiber-reinforced composites (NFRC's) and bio-degradable resins are used extensively for automotive, construction and other applications. The hybridization of synthetic fiber with natural fiber has gained the attention of researchers. The axisymmetric components such as pressure vessel, driveshaft, storage tanks, pipes, etc. are fabricated by filament winding process. Commonly glass, carbon, aramid fibers are used for this process. The use of natural fibers is challenging in filament winding as these fibers are not continuous, hydrophilic nature, poor bonding with matrix, available geographically, less tensile strength as compare to synthetic fibers. This paper is intended to explore the potential of natural fiber for the filament winding process. High cellulose content and low microfibril angle (MFA) in plant fiber are responsible for the high strength of the natural fiber. Surface modification techniques improve the adhesion between fiber and matrix which results in improving the tensile strength of the composite. Few researchers used sisal, flax and jute fiber for the filament winding process. This paper contains, an outline of filament winding process parameters like fiber tension, winding pattern, winding angle, optimum winding pattern and potential of few plant-based natural fibers and their properties have been highlighted for filament winding process. Also, surface modification techniques to improve the tensile strength of a few plant-based fibers are also been discussed. The global composite pressure vessel synthetic material market is expected to grow at a Compound Annual Growth rate (CAGR) of 23% from 2017 to 2023. The development of a new hybrid composite made of natural and synthetic fiber suitable for filament winding need to be discovered. © 2021 Elsevier Ltd. All rights reserved.

Biodegradable composites for filament winding process

In recent years, compressed natural gas (CNG) as a fuel for the automobile is overgrowing, as it is cheap and environmental friendly compared to gasoline and diesel fuel. To improve fuel efficiency, lightweight composite pressure vessel tanks are used for the storage of CNG. Due to high specific strength, fiber-reinforced composites are most widely used. Synthetic fibers like carbon, glass fiber are used for the fabrication of these pressure vessels. In the last few decades, due to environmental concerns, the hybridization of synthetic fiber with natural fiber has gained the attention of researchers. This paper focuses study on the effect of adding natural fiber on first ply failure (FPF) pressure based on the Tsai-Wu failure criterion. The laminate stacking sequence on first ply failure pressure for carbon/epoxy, E-glass/epoxy, and hybridization of these fibers with abaca fiber is studied. Abaca is strongest among other natural fibers as it contains high cellulose which is responsible for strength of the fiber. CNG tank with a 30-liter capacity, inside diameter 261mm, thickness 12 mm, applied pressure of 25 MPa with both ends closed is considered. Stacking sequence of symmetric laminate [(90)2/∓θ/(90)2]S, for different orientation of helical winding i.e. θ = 150,250,350,450,550,600,750 is analysed for these composite materials. A hybridtube made of synthetic and natural fiber with uniform thickness is considered. The simulation results of the first ply failure pressure are compared with theoretical results. Autodesk Helius Composite software is used for calculating material properties and, first, ply failure analysis. It is observed that burst pressure decreases as helical angle θ increases, and for the stacking sequence of [(90)2/∓150/(90)2]s burst pressure is maximum for all tubes. The Burst pressure of the hybridcarbon/Abaca tube reduces by 69.5% to 42%for winding angle between 150 to 450 compared to standard carbon tube. For hybridE-Glass/Abaca tube, burst pressure reduction was 21%to 4.7%for winding angle between 150 to 450 compared to standard E-Glass tube. For hybrid Carbon/Abacatube, the drop in burst pressure is less 23.7% to 1.74%,respectively, compared to carbon tube for helical angle in the range 550to 750.Slight improvement in burst pressure (1.14% to 7.5%) is observed for the helical angle between 550 to 750in the case of a hybrid E-Glass/Abacatu be compared to the E-Glass tube only. For the E-Glass tube, intermediate lamina can be replaced by Abaca fiber. Copyright © 2021 by ASME

First-Ply Failure Pressure of Symmetric Laminated Hybrid Composite CNG Tank

A car's engine cannot power all of the wheels alone. That’s why the drive shaft is necessary to propel the vehicle. To propel the drive wheels it is necessary to take power from engine and send it to drive wheels by means of a drive shaft (half shaft). As it is transmitting the torque from the engine to the wheels, the drive shafts are subjected to the torsional stress and shear stress, which cause the failure of drive shaft. Any break down in drive shaft will cut the power flow from engine to the drive wheels. That’s why it is indispensable to analysis the drive shaft. The properties required to the drive shaft are hardness on the surface to resist the wear and toughness in the core to resist the deformation that can be achieved by doing the heat treatment.
