The main objective is to Extraction of cellulose nanofibers using Mechanical ball milling Process and Chemical Treatment Methods. The Nanofibers are incorporated with Epoxy Matrix to make composite plates. Mechanical properties such as tensile strength, Flexural strength, and impact energy are evaluated. Mechanical Extraction method such as Ball Milling is carried out for 2 hours and 5hours. Using SEM image the ball milling powder are visualized to determine the diameter. In Chemical Treatment Methods three Different kinds of Treatment are performed namely sodium Hypochlorite, Sodium Hypochlorite, and Acetic acid. Using Handlay up method these fibers are incorporated into the epoxy matrix to fabricate composite plates. The ball milling process is carried out without any chemical Treatment process. Increases in milling process result in the chance of occurring Nano fibers. In my study Nano sized fiber is not obtained, only the 28 microns fibers are converted into 3-4 microns. In chemical treatment process three samples C1, C2, and C3 are prepared the difference in a sample is the employment of chemicals. Sample C1 gives better dimensions of fiber because the sodium hypo-chlorite remove the lignin and pectin content since the chemical is Basic in nature. While in sample C2, C3 equal amount of acetic or only acetic acid neutralize the basic content Mechanical properties show that chemical treated sodium hypochlorite sample gives better Mechanical Properties. Better strength is achieved with a chemical samples here water absorption test is carried on all the chemically treated samples The result shows the sodium hypochlorite sample absorbs less amount of water and its mechanical strength is decreased compare to the mechanical properties. Experimental and theoretical tensile strength are examined using different theory models .The result depicts that Hirsch model is very far from experimental value. The future work is to treat the fiber with different proportion of chemical A hybrid composites are prepared with varying the volume fraction of fiber. Free vibration test should be conducted on hybrid composites.
