Properties  Highest tensile strength of any material EVARRR!!!!  63 GPa compared to.4 GPa (structural steel ASTM A36)  1/50,000 th the width of a human hair  132,000,000:1 possible length to diameter ratio  Up to 18 cm in length  Made up of hexagonal structures that can be linked to form strands or sheets.  Highest tensile strength of any material EVARRR!!!!  63 GPa compared to.4 GPa (structural steel ASTM A36)  1/50,000 th the width of a human hair  132,000,000:1 possible length to diameter ratio  Up to 18 cm in length  Made up of hexagonal structures that can be linked to form strands or sheets.

Current Applications  Cement Based Foam Concrete Reinforced by Carbon Nanotubes  Increases foam concrete’s compressive strength by up to 70% making it comparable to conventional concrete at approximately 2800 psi  50% less dense than conventional concrete with an average density of under 70 lb/ft^3  Easy to pour as a slurry  Carbon nanotubes make up 0.05% of the mix by mass.  Reduce heat conductivity between 12-20%  Used in resins, which makes composite materials 20-30% stronger. (Chemically bond to epoxy)  Found in wind turbines, hunting arrows, and surfboards.  Cement Based Foam Concrete Reinforced by Carbon Nanotubes  Increases foam concrete’s compressive strength by up to 70% making it comparable to conventional concrete at approximately 2800 psi  50% less dense than conventional concrete with an average density of under 70 lb/ft^3  Easy to pour as a slurry  Carbon nanotubes make up 0.05% of the mix by mass.  Reduce heat conductivity between 12-20%  Used in resins, which makes composite materials 20-30% stronger.
