Hybrid Ceramic Armor!

(huge thanks to Chris for coming out and shooting with me, if you want to check out his youtube channel heres a link:youtube.com/@c...
this project video I showcase some ceramic/elastomer hybrid strike faces that can handle some serious damage. It covers topics such as: LIBA armor system and similar patents, the T-64 ultra porcelain armor, proper packing configurations of ceramic balls (including circle packing and sphere packing problems.) Different elastic resins, and where to go from here. I hope this video and PDF paper serves as a guide for those interested in getting into more dynamic armor systems. This was a really fun project to work on, and I'm excited to finally show it off. This video is much longer than others I've produced, however I felt like it was needed to get all the information out. I really think this could be expanded on, to create Flexible rifle-rated armor.
Here's the links for all the materials used, and articles quoted and photos used.
First, links for the materials.
Porcelain balls were bought form this distributor on ebay: www.ebay.com/s...

simpact resin 85A and 60A was bought from this website (and information and data sheet was used from there.): www.smooth-on.... you can use that website to find a local distributor as well.
Now onto the sources, first up LIBA armor information:
