What is a strong lightweight material that would be good for military grade body armor?

I want to design a military style bullet proof vest and I have a good design but need a few materials to tests, any suggestions?What is a strong lightweight material that would be good for military grade body armor?Probably a boron carbide or silicon carbide ceramic baked over a kevlar inter-liner. US military currently uses the ceramic insert, or SAPI (small arms protective insert) as its primary means of halting the puncture function of high-speed projectiles (bullets) to vital areas, while relying on kevlar to slow the penetration of slower shrapnel materials to non-vital areas by hampering the penetration of non-linear non-symetric projectiles through successive disruption of momentum and inertia the subsequent layering. The ceramic plate provides superior protection to high-speed impact, but is successively weakened to consecutive impacts due to its frigid-to-non-existant malleability. A kevlar-meshed interlayer would greatly improve the resilience of the ceramic plate. This, however has yet to be developed, as a means to cure the ceramics while maintaining the tensile integrity of the kevlar within the plate has not yet been developed. Could a production method be developed though, this would probably be the most effective composite.

(However, if this question is in reference to a home experiment or school project, I would suggest leather, ballistic nylon, shorn carpet, linoleum, 1" ply rubber, etc. And only under parental supervision.)What is a strong lightweight material that would be good for military grade body armor?
Buckminster fullerines, if you can get your hands on them. Woven nanotubes would be good as well.What is a strong lightweight material that would be good for military grade body armor?I was going to say silk, but upon further investigation I found that modern munitions are simply too fast and powerful..What is a strong lightweight material that would be good for military grade body armor?
illegal to let you know. kevlar is found on many tires tho.What is a strong lightweight material that would be good for military grade body armor?I wouldn't feel safe wearing body armor made from a guy that had to ask people on Yahoo Answers for help
