Moisture absorption and Chemical resistance studies on Pineapple fiber reinforced Vinyl ester Composite

Abstract

This research discusses the moisture absorption and chemical resistance studies on pineapple fiber reinforced Vinyl ester composite. A composite material was developed with pineapple fiber as reinforcement in the Vinyl ester matrix. Pineapple fiber of three different weight percentages 30%, 40% and 50% wt as well as fiber length of 30mm, 40mm and 50mm respectively taken for the study. The moisture absorption and the chemical resistance property of the composite were investigated as per the ASTM standard. Five different chemicals were used to investigate the chemical resistance behavior of the composite. The initial and final weight loss of the composites was calculated to find the moisture resistance property. The chemical resistance property was increased with the addition of treated jute fiber. All the tested composites exhibited positive results on the chemical resistance test
