Development of mathematical models to predict tensile properties of ‘carbon nanotube coated carbon fibre reinforced polypropylene (CNT-CF/PP)’ composite is briefly discussed. In order to incorporate the work out, Halpin-Tsai and Combined Voigt-Reuss model has been implemented. Reference composite was taken on the basis of highest amount of CNT growth over carbon fibre tows. Young's modulus for CNT-CF/PP composites has been found 4.54 GPa and the tensile strength has been estimated 45.37 MPa considering the optimum operating condition of chemical vapor deposition (CVD) technique. Stiffness of the composite is represented through the stress-strain plots; stiffness is proportional to the steepness of the slope. There are slight deviations of results that have been found from projected theoretical method over the experimental findings.
