Evaluation Of Mechanical Properties Of Sustainable And Low Cost Coir Fiber Composite: An Experimental Approach

Abstract

Now day’s upcoming composites are concentrating on natural fiber like: Coir fiber; banana fiber; jute fiber and pineapple fiber etc. Natural fibers are used to make reinforced composites because of its accessibility, durability and adaptability. Simultaneously, these composites should be environment friendly, and its biodegradable. The emergence of green fibers leads to lesser ecological effect because of the biodegradable qualities in its production.
The mechanical behaviors of coir fiber-reinforced composites in terms of tensile, flexural, impact, and hardness were tested, according to ASTM standards, and tested done in well proof lab (MRC lab in MNIT Jaipur). The short treated coir fibers were utilized in reinforcement composite material, with varying ratios of length and made 3 composites (C1, C2, C3) with 30% coir fiber, epoxy resin (LY-556) as matrix material, and hardener (HY-951) both took 70% as the ratio of 10:1 and fly ash as a filler material used last two composites (C4, C5), in C4 fiber-25%, metrix-70% and filler-5%, similar in C5 fiber-20%, metrix-70% and filler-10%.
