Hypersonic shear thickening - GC's secret sauce

(Just posted on our UK Crowdcube funding site: www.crowdcube.com/graphenecomposites) This is what our graphene/aerogel composite does - and to our knowledge, what no other material does. With "shear thickening" materials, the harder you hit them, the harder they get. "Hypersonic" means that it works at several times the speed of sound - as with high-velocity bullets.

In ballistics tests of our GC Shield versus high-powered, high-velocity bullets (e.g. NATO M80 7.62 x 51mm sniper rounds travelling at 2.5x the speed of sound, designed to kill targets a mile away) fired at close range (10 meters), with high-speed (100,00 frames per second) video, you can actually see the shock waves from the bullet impact shooting out sideways from our shield at nearly the same speed, whilst in the same 1/100,000th of a second, you can also see the front strike face of our shield puff out - back towards the bullet - using the bullet's own force against it - flattening or disintegrating it. This is what we call hypersonic shear thickening.

This is GC's secret sauce - it's what makes our GC Shields so effective at stopping (and flattening) bullets. It's also what makes it so good at force dispersion that there is virtually no back-face deformation on the back of our shields - and this means that there is much less damage to someone behind our GC Shield than with other shields.

This graphene/aerogel composite is also what makes our GC Shields so much lighter than other shields - especially at higher levels of protection.

Note that our graphene/aerogel composite, GC Shield, Shield Wall and Shield Curtain designs are all covered by patents pending. And we are willing to licence our GC Shield technology to existing armour manufacturers (provided that they meet strict UK/US security criteria) so that end customers (schools, police etc) can have greater access to our technology more quickly.
