Composite materials are replacing traditional materials because of their superior properties such as high tensile strength and high strength to weight ratio. Natural fibers such as bagasse and jute are abundant in nature, which have high tensile strength and low extensibility as compared to other natural fibers. In synthetic fibers, glass fibers are the most common of all reinforcing fibers for polymeric matrix composites. The main advantages of glass fibers are low cost, high tensile strength, high chemical resistance and excellent insulating properties. Epoxy resin has more strength as compared to other resins. Addition of small amount of chemically treated natural fibers to synthetic fibers may enhance the mechanical properties of resulting hybrid composites. The main aim of this work is to identify the optimal chemically treated natural fiber material to be used along with glass fiber in hybrid epoxy composites and to enhance the strength of the composites. In this work, the jute and bagasse fibers were treated with different three chemical solutions such as sodium hydroxide, potassium permanganate and stearic acid. The hardener polyamine 301 mixed with epoxy resin AE103 in the ratio of 1:10 was used. Specimens were prepared by compression moulding process, with five hybrid layers of natural fibers and glass fibers and allowed to cure for 3 hours. Specimens with both untreated and treated fibers were fabricated and their mechanical properties such as tensile strength, flexural strength are to be compared and the optimal chemically treated natural fiber material will be identified
