TRANSCRIPT
Liquid -Based Combat Armor
• Light and flexible body armor .
• Hardens instantly and reversibly, allowing thinner, lighter more flexible armor.
• Based on liquids that behave like a solid in especial conditions:
1. Shear-thickening fluid2. Magnetorheological fluid
Shear Thickening fluid (STF)
1. Hardens instantly2. Behaves like a solid
when encounters mechanical stress.
3. Formed of silica particles suspended in polyethylene glycol. Forming a Colloid
4. The energy of a sudden impact stick together the particles forming Hydroclusters.
5. Four layers of STF-Treated Kevlar can dissipate the same amount of energy as 14 of neat Kevlar.
6. Requires no electricity.
Magnetoreological Fluid (MR)
1. Hardens instantly, after a person actives the magnetic field.
2. Requires current traveling to create a magnetic field.
3. Based on a ferrofluid, “oils” filled with iron particles between 3 and 10 microns.
