Patent Category: 

Overview: 

Hybrid nanocomposite using polyester resin and nanoparticle-carbon-nanotube coated carbon fiber. This composite is more thermally stable, electrically conducting and shows significant improvement in modulus.

Key Features: 

  • Outstanding mechanical properties of carbon nanotubes are obtained (Young’s modulus of ~1.25 TPa, and Tensile strength of ~ 100 GPa] in a structural hybrid composite.
  • Problem of dispersion in the matrix is avoided as carbon nanotube are need not to be added during fabrication.
  • Excellent thermal stability and mechanical properties are obtained.

Applications: 

Wide ranging applications from aerospace, automobiles, medical applications, heavy machinery, space materials, chemical, civil engineering industries, etc.
