Mechanical Properties Of Sisal And Pineapple Fiber Hybrid Composites Reinforced With Epoxy Resin

In this study, Work has been carried out to investigated tensile , bending and impact properties of hybrid composite of material constitutes sisal fiber and less discovered pineapple fiber. These composites are adhered using epoxy resin cosists HY951 resin and LY551 hardener suitably mixed in appropriate volume. Hybrid composites were prepared using sisal/pineapple fibers of 100/0, 70/30, 50/50, 30/70, and 0/100 Weight fraction ratios, while overall fiber weight fraction was fixed as 20gram. Here for preparing samples Hand lay up method is used , specimens are prepared , fibers are arrenged in unidirectional manner and tests are carried out , which shows tensile and bending strengths. The tensile & compressive test was applied on specimens of 300×50 & thickness varring from 4-6 mm in dimensions but in different proportions of sisal and pineapple by weight. The test result shows , the composite made by 50/50 fibers weight fraction of sisal & pineapple fiber has been shown best impact strenght 47.2 N/mm 2 as compare to other constitutes of sisal & pine fibers.this constitute have good tensile & bending strength & their density is also less than sisal fibers. These composites can be used in various purposes because of its unique features of recycleability, waste utilization, environment friendly, bio-degradibility, good strength and a good alternative to plastics.
