Hello ladies and gentlemen! I could use some diverse minds to help me solve a problem with a potentially life saving piece of equipment. I am looking for a material that is lightweight, cost effective and has good anti-ballistic property's. I work in an environment where knifes and ice-pick are a greater threat then bullets. After a close call and armor failure, I am needing something better.
I am playing with the idea of making a flexible roman reminiscent lamellar armor .I am currently working with Kevlar, HDPE specify delrin (polyethylene high-density) , Fiberglass (resin coated) ,vulcanized rubber, aluminum and PVC sheeting. My goal is to make round laminated disc to stack and intertwine with dyneema cord.If you are aware of any materials that could help me that is cost effective, please let me know. This is my first post here. Any input will be greatly appreciated! Sorry if I didn't follow correct posting protocol. I figured the most appropriate place for this was under physics or possibly engineering.
What the vest is up against: "The ice pick has a 4 mm (0.16 in) diameter with a sharp tip with a 5.4 m/s (17 ft/s) terminal velocity in the test."(wikipedia.org/wiki/Ballistic_vest)
