Chemical and Water Absorption Behaviour of Hardwickia Binata Fiber Reinforced Composites

Abstract

In recent years Natural fiber reinforced polymer composites have been used in the engineering applications.Composite materials possess high strength to weight ratio, and due to these facts composite materials are becoming popular among researchers and scientists. The major proportion of engineering materials consists of composite materials. Natural fiber reinforced green eco-friendly composites made from jute, hemp, sisal, banana, coir, green bagasse from the natural sources provide indisputable advantages over synthetic reinforcement materials such as low cost, low density, non-toxicity, comparable strength, and minimum waste disposal problems. In the present work, natural fiber Hardwickia Binata was introduced and composites were prepared varying fiber loading like 5%, 10%, 15% and 20% using hand lay-up process. Water absorption and chemical resistance properties were examined for the fractured fibers. Scanning electron microscope (SEM) analysis is carried out and analyzes the structure of the fractured surfaces after water absorption

Impact Strength, Water Absorption and Chemical Resistance of Untreated and Treated Cordia-Dichotoma Fiber/Polyester Composite

“…This study concludes that water absorption increases with increase in fiber content and it follows Fickian behavior; chemical resistance decreases with an increase in the fiber weight ratio and was maximum for 10 weight percentage of fiber. The chemical resistance test was conducted by a few researchers and observed their behavior and found that there was a weight gain for some acids and bases meanwhile there is some weight loss also observed for few [20,21].…”
