Abstract—The technologically advancing society is continuously challenging the limits of conventional materials and placing newer demands on material performance. Composite materials form a material system composed of a mixture or combination and are insoluble in each other. Composite material comes under one class of engineered material developed specifically to meet such a challenge. Glass fiber reinforced resin matrix composites were first introduced in the early 1940s. Since then, the use of composites is growing steadily in various industries such as aircraft, marine, automobile, sporting goods, etc. Some of the advantages of composites include high specific strength, high specific stiffness, fatigue strength and impact resistance, thermal conductivity, corrosion resistance, and good dimensional stability. Composite materials are usually designed to possess certain specific properties desirable in that application. Unusual combination of properties not easily obtainable with alloys such as higher fracture toughness, higher oxidation and corrosion resistance, directional properties, good resistance to heat, cold and moisture, ease of fabrication and low cost could be brought out; of course, not all together simultaneously. In our project work we have developed hybrid FRP composites (Glass and Fly ash reinforced vinyl ester polymer) using hand lay-up process. The materials are subjected to tensile and bending tests as per ASTM standards.

Index Terms—FRP, Glass-fiber, Flyash, Vinyl ester, Hand lay-up method, ASTM standards
