MiralonTM

4

Carbon nanomaterial imparting effects such as

• Electrical conductivity

• Flame resistance

• Thermal conductivity

• Corrosion resistance

• Mechanical damping

• Performance enhancement in composite systems

The properties of MiralonTM are being developed & used for aerospace, industrial and construction applications

Scale of structural materials production today

What are we competing against?

Carbon fiber

145 Thousand Tons

• High volume structural materials on a global basis

• Commodity materials in billions of tons through to high performance in kilo tons

• Replacing all steel used in auto is approx. 200-300MT

• Need for multiple large scale methane pyrolysis plants in megaton range to compete

• To make a high volume impact quickly, need to focus on construction applications with less demanding performance needs

Cement - 4.4 B tons

Concrete 40 B Tons

Steel 1700 Million Tons

Current view of performance targets

7

• Global concrete market approx. 40Bn

tonne per annum

• Volume potential around 5.6 megaton

at estimated carbon concentration

• Roads and infrastructure 1-1.5 megaton

• Challenge to disperse into highly

viscous material

• Interaction with other additives etc to be

taken into account

• Cost target <$1-2/kg to be competitive

• Wear resistance >50% of standard

concrete to be lifetime cost attractive

• ASTM C494 standard / NTPEP

certification

• Compressive / flexural strength > 90%

of reference concrete

• Freeze &thaw / shrinkage attributes

Concrete additives

Extending concrete lifetime

Replacing steel rebar with Miralon

reinforced polymer

Current view of performance targets

8

• Rebar addresses limited tensile

strength and ductility of concrete

• 300MT volume pa, $300Bn market

• Alternative CFRP, GFRP etc being

developed but niche products

• Pultrusion process needing

impregnation with epoxy resin –

production speed is critical

• Chemical and corrosion resistance is

key

• Multiple standards / specs – inc ACI

440 / ASTM D7205/D7205M-06

• Modulus higher than 124 GPa for mass

market & compete with steel

• ~50-70 GPa modulus & 500MPa tensile

strength to compete with GFRP

• Address other FRP weaknesses by

improving creep-rupture and fatigue

• Price needs to be <$1/kg to be

competitive

Barriers to commercialization

Roadblocks to be overcome

• Creating the scale for desired impact on climate

• Cross linking of carbon nanomaterials for structural

applications or megaton expansion of petrochemical

resins?

• Logistics and supply chain – huge volumes of solid

materials to move and locations may not match where

demand is located

• EHS / toxicology data and end of life disposal

challenges

• Collaboration –science, engineering and capital

investment beyond a single company
