Mechanical Characterization of Hybrid Polymer Composite for Marine Application

An investigative work was conducted to examine the tensile, flexural and impact strength of carbon fiber reinforced vinyl ester composites filled with different proportions (0, 0.5, 1, 1.5 and 2) of graphitic carbon nitride (g-C3N4) and silicon nitride (Si3N4) filler. Composites were fabricated by hand layup method. Results showed an increase in tensile strength of g-C3N4 and Si3N4 particles content by 1% and beyond which the strength decreased. With the addition of 1wt% of g-C3N4 and Si3N4 in carbon fiber reinforced vinyl ester composites, the flexural strength increased to 16% and the tensile strength increased by 10%. The eroded surface of specimen was observed under scanning electron microscope and the results are reported. Incorporation of nano fillers in hybrid polymer composite will enhance the mechanical properties. Hence hybrid C-V extensively used in marine applications.
