Investigation of tensile and flexural strength of sisal fiber reinforced epoxy composite with waste tyre rubber particle as filler

The world’s tendency toward utilizing reused materials requests new items from natural resources and waste polymers. In this work, composites made from waste rubber particles (average particle size: 320 mesh) and sisal fiber in unidirectional form with matrix material as epoxy resin were prepared by hand lay-up method & investigated the mechanical properties for the influence of waste rubber particle loading in natural fiber composite. The effect of different loading of waste rubber particle (0,5,10,20 %wt) on the tensile and flexural strength was investigated. The results represent that 5%wt waste rubber particle loading composite shows maximum tensile and flexural strength & further increase in rubber particle loading shows decrease in tensile & flexural strength.
