Flexural and Specific Wear Rate of Seawater Aged Bamboo, Jute and Glass Fiber Reinforced Polymer Hybrid Composites

Abstract

Abstract Natural fiber reinforced polymer composites have been used in different industries because of its high specific strength, modulus, cheaper and biodegradability. However, natural fiber reinforced polymer composites have lower mechanical properties and degrades its mechanical properties through seawater aging or moisture absorption than the composites having synthetic fiber. Therefore, the hybridization of natural fiber with synthetic fiber is needed to improve its mechanical properties in seawater aged condition. In this present investigation jute, bamboo and glass fiber is taken as the reinforcement medium for the preparation of the polymer hybrid composites. Three variety of hybrid composites such as [GJB]s,[GBJ]s,[JBG]s were considered for this investigation. The specimens were aged in seawater for 30days. It is found that [GBJ]s hybrid composite absorb more amount of seawater than the other two hybrid composites followed by degradation of its flexural strength by 42% and modulus by 33%. The [GBJ]s type hybrid composites shows lowest specific wear rate than the other two hybrid composites in dry condition and for seawater aged condition [JBG]s type hybrid composites shows minimum specific wear rate as compared to other hybrid composites
