Evaluation of mechanical behavior for animal fiber Reinforced hybrid fiber composite for marine application

Abstract

When natural fibers are bonded together with synthetic material, they exhibit increased mechanical properties which are environment friendly and of low cost. The application of natural fibers as a substitute for chemical fibers draws great interest due to its less weight, lower raw material price, and ecological benefits of using green resources which are biodegradable and renewable. By combining these natural fibers in different compositions, the above-mentioned properties can be enhanced. In this investigation the natural material of goat woolen fiber, hen feather fiber, human hair fiber and synthetic aramid material of Kevlar 29 (K-29) are reinforced with Epoxy resin by hand layup technique and three samples are prepared at various combination. To distribute uniform pressure on sandwiched layers a method called Compression Molding is followed. Tensile strength, flexural strength is performed as per ASTM standard. In addition to this Water Immersion test is also carried out to determine the amount of water absorbed under specified conditions. Bonding layers and structure characterized by Scanning Electron microscope (SEM). The result proved that composite material is enhanced good mechanical properties and very less water absorption. It is used for light weight and for enormous applications in engineering industries and for lining materials of marine environment.

Sustainable engineering of human hair fiber-composite in engineering application

“…The composite is manufactured in physical fabrication by hand layup [12,14]. The plain square surface is chosen as the pattern dimension (300 × 300 × 3.5 mm3), over which a layer of wax is coated to release the composite removal after the manufacturing process.…”

“…Now the first layer of Kevlar bidirectional fiber is placed into the die, and epoxy resin with a hardener is rolled over the thread; a hand roller is used to move and distribute epoxy resin uniformly over the fiber. The process is repeated until the completion of all layer formation sequences (Kevlar Human hair (X-direction) +Kevlar+ Human hair (Y-direction) +Kevlar) by hand layup method [2,12,14]. Finally, a constant load (20 Kg) is applied to it for the uniform formation of epoxy resin, and then it is dried out at room temperature for 24 h. After a few days, a cured sample is cut into small sizes for testing [4,10].…”

“…This aligns with environmentally conscious construction, similar to concepts explored with natural fibers. Ongoing exploration promises breakthroughs in eco-friendly construction materials [13,14]. Carbon powder (HHC) is derived from human hair-reinforced polymer composite, which exhibits high-temperature resistance and structural application [15].…”

Review on Mechanical Characteristics of Kevlar Composites

“…Dinesh et al [13] examine the natural fiber composites made from hen, goat hair fiber, human hair, Kevlar followed by the tensile, flexural and water absorption test. It was found that the sample made from the composition of Kevlar and human hair had resulted in the best sample for tensile and flexural applications as it generated very high values of strength.…”

An overview: characterization of natural fiber reinforced hybrid composites

“…The animal fiber like goat hair (diamond hair) possesses great insulating property and elasticity, moisture-wicking property. Goat fiber is one of the most expensive fibers among animal fibers (Dinesh et al , 2020). Table 2 represents the mechanical properties of various natural fibers.…”
