A graphene enhanced resin composite that conducts electricity offers significant commercial advantages in aircraft manufacture. This could transform the wind turbine market as the resin can be heated and use to de-ice surfaces.

The video comes from an update by MD Mark Thompson back in December. We recommend watching the entire clip as he mentions other large volumne applications they are working on in sustainable packaging etc.

The Talga graphene enhanced resin can also be used in (conductive) concrete and other large scale commercial applications in construction and roading.

“Australia-based advanced materials technology company, Talga Resources, has reported outstanding conductivity results from its Talphene-enhanced epoxy composite trials undertaken at TWI in the UK.
 
Carbon fibre reinforced polymer (“CFRP”) panels were constructed using a dispersion of Talga graphene (Talphene) in the epoxy-based resin of the composite and subjected to a range of conductivity tests pertinent to aircraft applications….
 
Results reported by Talga showed the Talphene panel provided similar lightning strike protection as copper mesh panels currently used in composite aircraft but saved 75% of the weight of the copper.
 
Further results demonstrating Talphene’s significant conductivity included up to 500% increase in dielectric constant, 100% increase in resin thermal conductivity as well as spot temperatures well over 100 degrees celsius in anti-icing trials.
 
As CFRP resins are normally non-conductive, these results are said to be highly positive.
 
The ability to improve the weight, electrical and thermal conductivity of CFRP composites has significant benefits for applications such as lightning strike protection and wing anti-icing on aircraft, both of which currently use heavy copper mesh.
 
The same technology would also be of benefit to wind turbine blades that require manual or chemical de-icing in winter.
