Magnesium alloy nanocomposite prepared with hard ceramic particles via conventional technique is a promising future material for automotive applications due to its unique characteristics like low density, high strength, castability, and good wear resistance. The present study is to enhance the tribo-mechanical properties of alumina nanoparticle (10wt %) reinforced magnesium alloy (Mg/Al) composite by incorporating 1wt%, 3wt%, and 5wt% zirconium dioxide (ZrO2) nanoparticles through stir casting method. The tensile strength, impact toughness, hardness, and wear rate of developed composites were compared with (10wt %) alumina nanoparticles reinforced magnesium alloy composite. The nanocomposite containing 3wt% ZrO2 shows maximum impact strength of 22.8 J/mm2. The maximum tensile strength (88.9MPa), hardness (124.5BHN), and wear resistance (9.802mm3/m at 20N) are obtained for 5wt% ZrO2 magnesium alloy nanocomposite.

The main objective is to Extraction of cellulose fibers using mechanical ball milling process and chemical treatment methods. The fibers are incorporated with an epoxy matrix to make composite plates. Mechanical properties such as tensile strength, flexural strength, and impact energy are evaluated. Ball milling is the mechanical extraction method of producing nano size powder. The increase in milling process results in the chance of occurring nanofibers. The ball milling process is carried out without any chemical treatment process. In chemical treatment methods, three different kinds of treatment are performed namely sodium hypochlorite, sulphuric acid and acetic acid. Using hand layup methods these fibers are incorporated into the epoxy matrix to fabricate composite plates. In my study nanosized fiber is not obtained, only 28 micron fibers are converted into 3-4 microns.
