The Influence of Fiber Treatment on the Mechanical Behavior of Jute-Coir Reinforced Epoxy Resin Hybrid Composite Plate

The use of plant fibers to replace artificial fibers such as carbon fiber or glass fiber is the subject of studies by many researchers today. Vegetable fibers are considered for their renewability, degradability, low toxicity and low cost. In this work, the mechanical properties of tensile and flexural strength and modulus of elasticity of hybrid composites of sisal fibers with glass fiber in an epoxy polymer matrix were evaluated. The fibers were treated in a 10% by weight sodium hydroxide solution and subjected to tensile tests in a universal testing machine according to the ASTM D3039 and D790 standards. The best performing composites were the sisal + fiberglass hybrids, at 86% for the tensile strength and 64% for the elastic modulus. In the bending tests the results showed a performance of 119% for the maximum stress and 138% in the greater breaking stress for the hybrid composites.

“…Polyester resin matrix with density 1.1-1.5 g/cm3 was prepared by taking the required weight in a glass beaker and by mixing it with hardener methyl ethyl ketone peroxide (MEKP) with 1.5 % by weight and stirred for 2 minutes. Then cobalt naphthalene 2 % by weight was added which acts as accelerator and again stirred for 2 minutes and hence the matrix was prepared [34].…”

Fibre reinforced composites are used in automotive, defence and structural applications because of their economic and ecological advantage but they have limitation of lower mechanical strength. To balance this limitation of mechanical properties, hybrid composites are being manufactured. In this paper jute and human hair was selected for preparation of jute / human hair reinforced polyester hybrid composite. Human hair was selected because it is non-biodegradable and has high tensile strength. A single human hair can bear 1.5 Newton load. Recently various researcher started work towards development of bio-composites. It has been found that a mechanical property increases after adding hair in hybrid composites. Mechanical properties such as tensile strength, young modulus, and flexural strength were also compared with the already published jute composite results. To understand the fracture behaviour of composite morphology of the fractured surface was done by scanning electron microscope (SEM). The composite application is in environmental conditions addition and thus it is subjected to moisture presence, therefore study of water absorption behaviour of fabricated composite was also studied.

“…Owing to the growing concerns regarding environment and biodiversity, modern researchers and industrialists are continuously trying to develop eco-friendly products. Off late natural fibers like Sisal, Jute, Aloe vera, Hemp, Banana, Coconut etc, by virtue of certain special physical properties, such as biodegradability, renewable potential, flexibility, low density and abrasion rate, have gained significant traction for the potential it possesses to be utilized as reinforcements while fabricating composites [1,2]. Composite materials consisting of natural fibers are being extensively used in the automotive industry [3].…”

The research work aims to utilize one of the cheapest and most abundantly available natural fibre, sisal fibre, to fabricate a hybrid nanocomposite possessing high performance efficiency. Glass fibre (GFC), sisal fibre (SFC) and hybrid glass/sisal fibre reinforced epoxy laminate composites (HFC) were prepared and subsequently, three of the most promising nano-fillers, MXene (HFCMXN), Graphene nanoplatelet (HFCGNP) and Multi-walled carbon nanotube (HFCCNT), were added into the hybrid composite. The fabricated composites were comprehensively assessed and analysed for their mechanical properties, swelling and flammability behaviour. It was observed that the glass fibre reinforced composite had lowest void content (6.3%) and glass/sisal fibre reinforced laminate had the highest void content (17.2%). The addition of nano-fillers did not further enhance the void content owing to the relatively uniform dispersion of the nanoparticle, which was particularly ensured during the whole fabrication process. The incorporation of nano-fillers led to a significant enhancement in the mechanical properties; tensile and flexural strength being highest for composites containing two dimensional nano-fillers. The GFC exhibited minimum weight gain (2.25%) and least swelling thickness (1.66%) upon soaking. Among hybrid composites, nano-filler reinforced composites had relatively less weight gain post in comparison to the hybrid composite without any nano-filler. HFCGNP had a weight gain of 6.69%, as opposed to 8.51% observed in case of HFC. The nano-fillers acted as an effective water barrier that reduced the tendency of water absorption. Furthermore, upon flammability test it was found that the burning rate decreased in order of GFC, HFC, HFCCNT, HFCMXN, HFCGNP and SFC. The addition of nano-fillers led to a decrease in the burning rate owing to the promising flame retardant properties of graphene which suppressed flame propagation and helped in extinguishing the flame.
