These are non-abrasive and biodegradable materials. The composites of nat- ural fibers have unique properties compared with traditional composites of fiber. The main objective of the present study is the utilization of jute and coir fibers if reinforcement material for the fabrication of natural composites. To characterize the composites and develop a better understanding of these compos- ites, the physical and mechanical properties of these composites are evaluated to find hardness, flexural and tensile properties of the jute/coconut coir reinforced polymer matrix composite. It is found that the composite with the composition of 85% jute and 15% coconut provides higher tensile strength because of the higher wt % of the jute fiber. The composite with a composition of 50% jute and 50% coconut coir fiber behaves like semi brittle and ductile as it contains 50/50% jute and coconut fiber. Hence, from this study, it was concluded that composite specimens are fundamentally more durable than pure coir specimens. Ó 2020 The Authors. Published by Elsevier Ltd.

Introduction In recent years, there has been increased environmental aware- ness of natural fiber composite because of the expanding ecological mindfulness. Hence, natural fiber composites are progressively being used in different applications [1,2]. The improvements in ris- ing bio-based plastics are breathtaking from a mechanical perspec- tive and mirror their agile development in the commercial center [3,4]. Singh et al. [5] reviewed the jute fiber and their composite and concluded that the fiber and their composites could replace of the steel, wood, and many more old materials in coming future. Many review articles are available in the literature on polymer matrix-natural fiber composites [6,7], and their mechanical behav- ior [8–10]. The effect on the morphology, crystallization, mechan- ical and warm PLA Lattice biomedical properties of bamboo cellulose nanowhisker was observed by Qian et al. [11]. We noticed that PLA/BCNW composites had a significant degree of straightfor- wardness and tensile modulus, with a 2.5 wt% BCNW material, and the BCNW reduced the malleable property. Prasad et al. [12] reported the properties of practically slope composites strength- ened with squander common fillers. They observed that the hybrid composite materials show lower tensile strength and moisture content and better hardness. They suggested the application of hybrid composites as an alternative to the glass fiber/natural fiber-based composite materials for medium structural applications. There have been few studies on composites of jute fiber and coconut coir separately. For instance, Naveen and Raju [13] evalu- ated the mechanical properties of coconut coir fiber reinforced polymer matrix composites. The experimental results have shown that the composites’ tensile, static and dynamic properties are sig- nificantly influenced by increased reinforcement levels. Research- ers have also suggested that coir can be used for many structural and non-structural uses as a possible reinforcement tool. Daramola et al. [14] studied the effect of pineapple leaf fiber content on https://doi.org/10.1016/j.matpr.2020.07.684 2214-7853/Ó 2020 The Authors. Published by Elsevier Ltd.
