Mechanical and dynamic mechanical analysis of jute and human hair‐reinforced polymer composites

Abstract

Application of light-weight materials in automotive and structural components such as door panel, Dashboard and internal engine cover play a crucial role in the improvement of vehicle performance. Weight reduction of automotive vehicle components results in less fuel consumption, leading to drastic reduction of CO 2 emission. Carbon emission can be minimized through replacement of light-weight natural fiber reinforced composite-based components in place of metallic components in the vehicles. Simultaneous application of heat and dynamic loads on polymer composite materials affect crystallinity resulting in the degradation of material properties and its weight. Many researchers have shown interest in the use of bio composites for automotive parts with good mechanical and thermal properties for conventional automotive materials. The present work focuses on the fabrication of jute and human hair-reinforced epoxy-based polymer composites with five different fiber compositions. Mechanical properties such as tensile strength and impact energy were analyzed. Storage modulus, loss modulus and damping behavior under different frequencies constituting a function of increasing temperature was observed. The effect of fiber composition and frequency on dynamic behavior of new combination of natural composites was analyzed for determining the viscoelastic behavior of composites. Mechanical properties were found to increase with increase in human hair composition in the composites. The glass transition temperature (T g ) obtained from storage modulus, loss modulus and damping curve exhibits a temperature between 80 and 958C for all composites. As a consequence, higher fiber content in matrix was observed to allow greater stress transfer at the interface resulting in high dynamic mechanical properties. The experimental results have shown that the natural fiber-reinforced polymer composite is sustainable in withstanding dynamic loads. POLYM. COMPOS., 00:000-000, FIG. 13.

Mechanical Characterization of pineapple leaf fiber and corn husk powder reinforced epoxy composites

“…The formation of grooves roughens the fiber surface, thus increasing the interfacial bonding between fiber and matrix by interlocking mechanism. Similar mechanisms Figure 6: Fractured surface of sample A were due to interlocking as observed in our previous research works [25][26][27][28]. Figure 6 shows fractured surface of the composite A which is due to fiber pull indicating the weak bonding of fiber with the matrix.…”

Plant Fibers-Based Sustainable Biocomposites

“…As a result, higher fiber content in matrix was observed to possess greater stress transfer at the interface resulting in high dynamic mechanical properties. Addition of jute and human hair with epoxy matrix shows enhanced viscoelastic behavior of the composite material [66].…”

“…A fibre is considered by its length presence some better compared to its dimensions. Jute fibers are fully bio-degradable, recyclable and environmentally friendly [4][5][6]. Hybrid is the flexible system with unique properties in which combined two or more fibers types to design composite materials that overcome the drawbacks of individual fibers composites [7][8].…”

“…Measured the devotion between the fibre and matrix surface and determined that the mechanical properties can be enhanced by chemical methods and new processing techniques [8][9][10][11]. Several natural and synthetic fibres are like flax, jute [5], oil palm [16,18], basalt, cotton [15], Kevlar, coir [14] carbon [20], Americana kenaf, sisal [13], glass [17] and banana are used for commercial purposes. Basalt fabric is a material prepared from extremely fine fibers of basalt.…”

“…Currently, hybridizing natural fibers with synthetic fibers, getting innovative consideration, to prepare a composite with improved properties, such as low cost, light weight, ease of fixing. Among several types of natural fibres, jute fibre has a high content of cellulose which considers an attractive option for the special engineering materials such as construction structures, building, automotive, aerospace, biomedical materials, in an eco-friendly manner [3][4][5][6][7][8][9][10][11][12]. In last decade, natural fiber reinforced epoxy resin composites have attracted growing research benefits owing to their potential as a substitute for composites reinforced with synthetic fibers like basalt, glass, Kevlar or carbon [13][14][15][16][17][18][19][20].…”
