Talk:Bulletproofing

Samurai Armor History Adittion

In the Japanese Armor wiki page there's mention of "tameshi gusoku", or feudal Japanese bulletproof/bullet resistant armor. However, that page only lists a visual media source for this type of armor, and there's little written on it there. If we could locate a stronger source for this it could be a win for both the bulletproofing page's "development" section and the Japanese Armor page, but I'm personally having trouble finding anything online regarding it. — Preceding unsigned comment added by Laldowaldo (talk • contribs) 20:34, 13 June 2022 (UTC)

Since Body armor redirects to Bulletproof vests, should we remove this "duplicated entry" in the Uses list? --Hurricane111 13:55, 10 August 2005 (UTC)

Fat

I have removed the uncited paragraph added by anonymous user User:82.11.31.111:

A layer of 60cm of fat is enough for a human to become bulletproof. Carrying this much fat however has its own health risks.

This seems is a bit too bizarre to go in the article, at least in this form, and according to what I assume is the source (see below) is not actually correct. The source concedes that it would not make someone genuinely bulletproof, for instance they would still be vulnerable to serious harm from the shock wave or from more energetic bullets.

A quick search shows it possibly comes from Times Online[1]. It answers a question about how much fat you would need to prevent a bullet reaching an internal organ. It refers to a book, Compendium of Modern Firearms, K. Dockery and R. Talsorian (Games, 1991), that states that a 9 mm handgun bullet can penetrate about 60 cm of flesh but damaging 1 cm³ of tissue for each cm travelled. The article suggests that this might be an underestimate because fat is less dense and softer than muscle, and then discusses this result in some detail, for example concluding that such a person would weigh 650 kg!

Term bulletproof

The term "bulletproof" was coined in the Middle Ages when plate armor was shot with a firearm before being delivered to the owner. The dent in the armor made by the bullet was the "bullet proof,"[citation needed] showing the purchaser that the armor could withstand a hit from a firearm. They didn't have firearms in the Middle Ages, gunpowered canon's came to europe in the late 1400's and was until around 1600 that handheld firearms were invented. This story seems very unlikely. —Preceding unsigned comment added by 60.242.110.77 (talk) 13:46, 14 June 2009 (UTC)

Arrow-proof

I read in a history of Gengis Khan that some of the combatants of the time had realized that wearing silk helped to remove arrows from wounds more safely. So, is arrowproofing a precedent of bulletproofing? --Error (talk) 19:31, 26 July 2015 (UTC)

Material characteristics

Under Invention and Design, there is the opportunity to include some technical discussion of specific material characteristics and analytics from which "bullet proofness" can arise. For example in the case of fibers, strain rate is crucial as it embodies the speed at which the impact pulse is spread (dispersed) across the material. A further, related topic could be impregnating fabrics with (non-Newtonian) Shear thickening fluids (STF) aka dilatant. The purpose of such content would be to guide the reader to explore some of the underlying physics regarding kinetics, deformation, shear, and computational domains such as Elastic Plastic Impact Computation (EPIC), etc. Does anyone have an objection to mentioning these topics?
