Influence of Distinct Environment on the Mechanical Characteristics of Arhar Fiber Polymer Composites

Abstract

Over the past decades the need for eco-friendly, non-toxic and biodegradable material is growing significantly. Natural fiber polymer composites have become the prior choice for many applications, as the natural fiber polymer composites are economical and eco-friendly materials in contrast with synthetic fiber reinforced composites. In the current study arhar fiber is used as a reinforcing material. Arhar fiber epoxy composites are fabricated using the hand lay-up technique. The materials were tested for weight gain in different environments (saline water, mineral water and subzero temperature condition). The composite samples immersed in the different environments were tested for tensile strength. It is observed that weight gain is more in mineral water and saline water, minimum weight gain is observed in subzero condition. Maximum tensile strength is observed in 10%fiber content samples. Strength depreciation ismore in samples immersed in the saline water environment.
