Background
•	Conventional Body Armour
–	 Multiple Layers of neat Kevlar stitched together 
–	 Rigid plates from pressed phenolic resins w fabrics
–	 Rigid ceramic SAPI inserts for higher threat levels 
–	 Long production times
–	 Lacks modular field serviceability
2. Extremities protection 
–	 Non existent
–	 Reister 1973 statistics from WWII and Korean War battlefield
–	 16% of deaths due to trauma to extremities
–	 70% of non fatal injuries to extremities
3. Agility 
–	 Present system limits mobility agility

Material considerations
•	Flexibility
•	Low Bulk
•	Cost savings
•	Lightweight
•	Protective increment
•	Wider application base
Other Parallel Researches
•	US Army Research Lab
•	University of Delaware
	Department of Chemical Engineering
	Centre for Composite Materials

Weakness – high OH content, two high hygroscopic components – PEG and silica
Our solution – lower risk of hydrolysis with higher ceramic content
Hand Stab Test Demo
•	2 samples K29, 215g/sqm density
•	One treated 20% density, one untreated
•	Untreated easy of penetration via stabbing utilizing Japanese paring knife
Hand Stab Demo Treated
•	Fabric Treated with 12% liquid ceramics
•	Stab 4 times
•	Little pulling due to locking of fibres
•	More fibres being utilized to resist stabbing
•	Lower density anti stab vest required
Colloidal Mechanism
•	Suspension fluid is used to hold up nano ceramic particles
•	Super saturated solution causes network to form when impregnated into fibres and dried
•	Super saturation lowers hygroscopic PEG content and increases ceramic content
•	Ceramics network formed from linked agglomerates and aggregates has faster locking time on impact

Locking Mechanism
•	Networks collide when projectile hits it causing the material to become macroscopically rigid
Aerospace applications
•	C130 interior Panels
•	Helicopters interior Panels
•	Advantages
•	Soundproofing

Fabric Pulling Neat
Treated Fabric Pulling Patterns
Fibre Locking Mechanism
Advantages
•	More fibres tensioning involved other than the common 2 axis
•	Nano Ceramic particles forced out of the suspension fluids after resisting projectile with negative normal forces dissipating kinetic energy
•	Low force flexibility
Normal and Bunch Pulling
Why Use Colloidal Technology?
•	Hybrid stab/ballistic vests now possible with lower cost aramid fabrics
•	Soft and permanently flexible
•	New market potentials in aerospace, B type vehicles, tents etc
Comparison With STF
•	20% impregnation required for ARL STF
•	We require less than 12% 
•	More ceramic content at 66 to 75% over ARL’s 50 to 65%
•	Smaller particles to go in between fibres for better locking and reinforcement
•	We developed anti-hygroscopic production techniques
ARL STF 20% Vs 6% Protectron 
Variables
•	Know-how for calibration of gel
•	Particle size and blends
•	Use for SAPI inserts for 
–	Bullet fragmentation
–	Stab knife
–	Stab spike
