In this recent world the fiber strengthened composite materials are synthesized using glass fiber as reinforcements together with matrix, which have attracted the attention of researchers due to their low density with high specific mechanical strengths, convenience, and renewability. The current work efforts to make a development in the current existing helmet manufacturing procedure and materials used to have better mechanical properties as well as to enhance the compatibility between fibers and the matrix. The composites are ready with the unsaturated polyester matrix and fibers such as, reinforced composite materials and glass fiber using hand lay-up method with suitable proportions to result in helmet shell construction. The fabricated helmet are planned to estimate its mechanical properties such as tensile strength, impact strength and compression strength.

The advancements in the field of application make the study of their wear and tensile behavior of utmost importance. In this present investigation, Aluminum based alloys containing 7%, 12% and 14% weight of Silicon were synthesized using casting method. Compositional analysis and tensile studies of different samples of same composition have shown near uniform distribution of Si in the prepared alloys. Study of microstructure has showed the presence of primary silicon. Tensile tests were carried out with universal testing machine. Yield strength and ultimate tensile strength has increased with increase in silicon percentage. Wear behavior was studied by using computerized pin on disc wear testing machine. Resistance to wear has increased with increase in silicon amount. The worn surfaces were analyzed using scanning electron micros
