Bike Helmets made of paper!

Here's a couple of design ideas coming out of London for paper based bike helmets.

What do you think?

This one is designed to be a single use and then recycle:


This one is, at least the initial design, more permanent:

Gettin' in early with my I hope this thread delivers.

Now all I need is a Dr Pepper. Note that I correctly spelled "Dr" without the period.

No A&S, please!

Just the functional & practical.

If helmets aren't your deal, fine. Stay out of this discussion.

The first one developed by "designers", i.e. art students, gives absolutely no data on its efficacy in reducing force from impact. They may have passed "rigorous European safety standards in initial tests" but that statement means absolutely nothing. Is the helmet better than nothing? I don't know.

The second one is more interesting. In principle, the idea of "honeycombed" crumple-zone is solid, already with a lot of real-world application and there's no reason to believe this idea would not work with a bike helmet. According to the video, it absorbed 3x the energy as polystyrene helmets but that strikes me as a dubious claim since they didn't mention what type of foam helmets. Nevertheless, I think the idea *could* be made to work better than styrofoam at impact reduction and for cheap since the materials and production methods are already readily available. A collapsible model, presumably made to be transported in a small package and assembled by the buyer is a novel idea.

Paper as a material for helmets is interesting. I'll wait until there's more engineering involved...

Paper will work great, sure! Because nobody riding a bike ever sweats much. :|

Yes that poses a problem for durability, but there's already waterproof paper-based cardboard so I'm not sure if it's an insurmountable problem.

It's really quite brilliant, isn't it? (I tease my English friends!)

Seriously, a great idea.

Re: water resistance, the first vid said they're resistant for 6hrs thanks to addition of organic additives.

And the first is REALLY dorky looking. But it is one time use, 'sustainable' design. And how effective it is hasn't been really determined.

And can you imagine the 'helmet hair'?

As to the second design I think the impact absorption vs. plastic foam may be superior and have real merit.

The first one somehow reminds me of a dog-food bowl drunkenly strapped to the head with a necktie..

I was reading something where they made claims that the corrugated/honeycomb cardboard idea employed by the second design had superior impact resistance and energy absorption since it had good lateral distribution of force and near-complete direct deformation which is unlike Styrofoam which would rebound significantly more. I'll see if I can dig it up, it was pretty interesting.

Uh, they have them (only two though) in my little town of Savannah.

I think some other US cities have them too. Fox News was all pissed off about them if IIRC.

Meh. Helmets are worthless, for the most part. Cyclists think they are capable of delivering way more protection than they actually can. So, why not a paper helmet? Won't be any worse than the beer-cooler styrofoam ones.
