Composite Materials

Over 2000 years ago the first version of steel was born and we still use it today. The Tisdale Group is developing products that are stronger, lighter, easier to work with and cheaper than modern steel products and ceramics. This "next generation" of materials will revolutionize survivability, mobility and agility.

Arctic Shield: Our current material in development.

Our material is scalable (thin as a few millimeters to several inches or even feet depending on the requirements), easy to work with, very low cost, light weigh (101.23 lbs. at 12”x12”x6” with a Ti-6Al-4V outer shell, even lighter and cheaper with an Aluminum or polymer shell) and maintains a higher ballistic survivability than RHA (245.34 lbs. at 12”x12”x6”). The material can be made into any shape or size. Through initial computer simulations of 6” of material and a thin Titanium (Ti-6Al-4V) outer shell, we were able to effectively stop a 3.5” EFP. The slug of copper was 20mm in diameter, 52mm long, a rounded nose with a radius of 9mm and a temperature of 1400K. Its velocity was set to 2520m/s which yielded a kinetic energy of roughly 450kJ. We have also conducted live fire experiments with our material against live EFP warheads and have successfully arrested the projectiles. There is more work to do but we are very close to a viable product. The picture below is 2025 aluminum that was behind a section of test armor. It represented the back plate (there was no front plate) and as you can see the EFP did not penetrate the aluminum.
