Mechanical And Physical Properties Of Polyurethane Composites Reinforced With Carbon Black N990 Particles

The effects of carbon black N990 on polyurethane properties with different weight fraction 2 4 6 8 and 10 wt of the former were investigated in terms of tensile strength hardness impact strength flexural strength and density. The tensile strength increased when 4 wt carbon black was added. The Impact strength also improved by 33 at the same percentage of carbon black. Flexural strength improved by 12 at 6 wt. in comparison with the neat samples. Moreover the hardness and density increased with increasing carbon black fraction for all samples. Thus carbon black N990 acts as a particulate reinforcement that improves the mechanical properties of polyurethane.
