Comments on: A modernized steel helmet is simultaneously lighter than the PASGT and performs better against both fragments and handgun rounds https://www.isegoria.net/2023/05/a-modernized-steel-helmet-is-simultaneously-lighter-than-the-pasgt-and-performs-better-against-both-fragments-and-handgun-rounds/ From the ancient Greek for equality in freedom of speech; an eclectic mix of thoughts, large and small Thu, 21 May 2026 16:19:21 +0000 hourly 1 http://wordpress.org/?v=3.6.1 By: Isegoria https://www.isegoria.net/2023/05/a-modernized-steel-helmet-is-simultaneously-lighter-than-the-pasgt-and-performs-better-against-both-fragments-and-handgun-rounds/comment-page-1/#comment-3607616 Isegoria Fri, 26 May 2023 18:30:38 +0000 https://www.isegoria.net/?p=50035#comment-3607616 When I went to look up D3O, I realized I’d mentioned it here before:

As keen snowboarders, Palmer and Green drew inspiration from snow and decided to replicate its matrix-like quality to develop a flexible material that incorporated the dilatant fluid. After experimenting with numerous materials and formulas, they invented a flexible, pliable material that locked together and solidified in the event of a collision.

Team Wendy (yes, a real company) created a reactive foam helmet lining/helmet suspension system that radically reduced chances of traumatic brain injuries and offers more comfortable support in the typical kevlar helmet.

In terms of blast protection, there are interesting possibilities with regards to expansive fabrics (woven in such a way that volume increases when stretched, like a box unfolding).
