Jute-basalt reinforced epoxy hybrid composites for lightweight structural automotive applications

Abstract

The utilization of lightweight construction is one of the keys to increase the fuel efficiency and reduce the environmental effect of automobiles. Natural fiber composites are replacing expensive synthetic fibers increasingly commonly in the automotive sector. To further lower the weight and price of the vehicle without losing rigidity and strength, basalt (B) fiber could be incorporated into jute (J) fiber composites. For the generation of hybrid composite laminates, woven textiles made of J-fiber and B-fiber were combined with an epoxy matrix. The primary mechanical features of the J-B/epoxy composite laminates, including tensile, bending, shear, and bearing characteristics, were investigated. Hand lay-up approach was used to prepare the hybrid composite laminates. The impact of the number of J-plies relative to the number of B-plies on the mechanical properties was explored. The findings proved that the basalt/epoxy composite has the maximum ultimate tensile strength, young’s modulus, toughness modulus, bending strength, bending modulus, in-plane shear strength, and bearing strength. Whereas the J/epoxy composite showed the maximum failure strain and bending strain. Hybridizing J-fiber with B-fiber improved the tensile, bending, in-plane shear, and bearing characteristics of the prepared composite. The maximum specific tensile, bending, in-plane shear, and bearing strengths are displayed by 3B-2 J-3B, followed by 2B-4 J-2B.

Multi attribute decision making through COPRAS on tensile properties of hybrid fiber metal laminate sandwich structures for aerospace and automotive industries

“…It is worth noting that the modulus of toughness is the ability of a material to absorb energy in plastic deformation. It is defined as the amount of strain energy density (strain on a unit volume of material) that a given material can absorb before it fractures, which can be calculated as the area under the curve up to the break as follows: 49,51,62,76,77 where ɛ 𝑓 signifies the failure strain.…”

“…Two perpendicular strain gauges were involved on the contrasting surfaces of each test specimen to determine the actual tensile modulus (Eact.) and the Poisson’s ratio (v12). Strain gauges were used by many authors 49,74,78–81 to determine the actual tensile modulus (Eact.) and the Poisson’s ratio (v12). Strain gauges working principle is simple: the electrical resistance of a conducting wire is a function of the material’s electrical resistivity, cross-sectional area, and length.…”

“…46 Due to its low cost, lightweight, and availability, jute (J) is considered a promising natural fiber. [47][48][49][50] In spite of these advantages, J-fiber has some drawbacks and thus needs to be hybridized with other strong fibers. Based on the abovementioned literature survey, quite little work has been undertaken with a view to investigating the properties of jute (J)-reinforced polymer FMLs and their hybrids.…”

“…Due to its simplicity, low cost, and few infrastructure requirements, the wet-wrapping method was used to manufacture GFRE circular composite tubes reinforced with different wt.% of HNTs. 5,48,49 The manufacturing steps carried out at room temperature (25 ° C) can be described as follows: The mixture, consisting of epoxy/HNTs/hardener was regularly placed on the glass fabric, as shown in Figure 4(a). Glass fabric was impregnated using both a roller and a brush, Figure 4(b).…”

Comparative study on three body abrasive wear behaviour of natural compliant thermoplastic composite under dry and lubricated conditions

“…The hybrid composites developed with the combination of natural and synthetic fibers shows enhanced wear resistance and can be used in tribological applications such as sliding elements, sliding bearings, seals, conveyors, clutches, tyres brakes, etc. Jute-basalt reinforced epoxy hybrid composites for lightweight structural automotive applications was developed and assessed by Hassan Alshahrani et al 38 where it was found that hybridizing Jute fiber with Basalt fiber improved the tensile, bending, in-plane shear, and bearing characteristics of the prepared composite. Evaluation of mechanical properties of jute/glass/carbon fibers reinforced hybrid composites was carried out by Abd El-baky 39 where the results showed that the hybridization process can potentially improve the tensile and flexural properties of jute reinforced composite.…”
