Influence of Carbon Nanotubes on Mechanical Properties of Polyurethane Composites

Habib Siddiqi Ahsan Najeeb

The main purpose of this work is to investigate the influence of carbon nano tubes (CNTs) on mechanical properties of polyurethane composite. Synthesis of carbon nano tubes (CNTs) was done by solution processing method using N-methyl-2-pyrrolidone (NMP) and tetrahydrofuran (THF) solvents. The small compact particles of polyurethane was converted into blend polyurethane by heating at 100°C in tetrahydrofuran solvent (THF).Samples were prepared using different wt%ages of carbon nano tubes (CNTs) i.e. (i= 0, 0.1, 0.5, and 1) and Polyurethane (PU) i.e. (i=100, 99.9, 99.5, and 99) in respective order. These samples were characterized by stress strain curve, modulus of elasticity (E) and percentage elongation by using universal testing machine (UTM).The addition of 1wt% of carbon nano tubes showed the higher stress in 19.2551 N/mm² and respective strain in 700.2294. Maximum elongation and modulus of elasticity is 140.0459mm, 0.26N/mm² . Hence, results show that increase in stress strain, E, and percentage elongation is direct relation with nano particles.
