A composite material is a combination of two or more materials arranged in the form of layer one on the other layer using binding material through some prescribed methods. The Bio-epoxy composite is prepared by hand layup method using Bio-epoxy, natural fiber, and particulate here we discuss the properties and characterization of the composite such as reaction with moisture content in soil, degradability and reaction with water. In this paper, the moisture absorption rate as a function of time is discussed with reference to the Bio-epoxy prepared. The matrix structure is the same as that of any composite but the reinforced material used is the hybrid being the natural epoxy. The bio epoxy hybrid composite is having high moisture absorbing capacity which leads to low flexibility in the specimen. The natural fiber used here as well as the particulate is readily degradable in soil when exposed to a specific time. The matrix reinforced hybrid composite used here is flexible in its very nature indicating its adaptability to various uses. The composite is eco-friendly. There is also a comparison between the traditional epoxy and the bio composites to check the time required for degradation. The usage of these bio composites makes the surrounding less harmful and it also cost-effective. There was also a test conducted for bio composites with water and soil for 72 hours. The natural fibers used havea high affinity for water therefore degradation easily takes place along with reinforced particulate material that is Tulsi seeds. In this article synthesis and characterization of hybrid bio-epoxy composite, and the reaction of these composites in wet environmental conditions are discussed.
