martenistic stainless cage?

damn, do i look 200lbs? i must be drinking too much. maybe if i drink more you'll look how i pictured you....

uh, yes, same diameter tires as on a lot of jeeps but with softer rubber, going down slick rock or pavement and jamming on the brakes at 30-40mph.... if you don't think there's some decent forces there for the size of the tubing, you're nuts.

Tires might be the same diameter, but the section width and traction is much less than what we use on our Jeeps.
 
tire load and the torque applied is pretty damn different too :rolleyes:
 
how is this even still a discussion? you are comparing apples to oranges here Dan. a mountain bike frame is not subjected to anywhere near the forces that would be applied to a cage (internal OR exo) in a rollover situation... unless you are a 4k+ lb fatass dropping frame right onto a rock.

make a sample piece that hangs out on the side of your jeep and beat the shit out of it on some rocks, like was mentioned earlier. then make your decision.
 
it might handle getting smacked into rocks on the first day, but what about the first year? or second? .098 is thin. heck even .120 is too thin for certain areas (bumpers, sliders, corners) IMHO

seems like if you could get a thicker wall thickness it would be good though.

carbon fiber is strong, however, when it goes, it goes. there is no bending, there is only failure. i'd hate to be on my 3rd roll when the tubing shattered on the second.

having worked with fiberglass and carbon fiber products... this is wrong. it is not a rigid product.

you are able to see signs of wear and tear. fibers frey and show signs of stress. but the nice thing about fiberglass is its ability to absorb impact. if you have ever used a high end hockey stick, or felt a surfboard flex under your feet, you know what i mean. carbon nanotubing technology is a big deal, its strong enough to scafold an entire sky scraper, but much lighter.
 
ok, so while i'm rolling, i'll stop and look for signs of wear and tear before i finish rolling :D

you cannot always see carbon fiber damage, if the layers start to delaminate after an impact, you will likely not notice unless you go around tapping your entire cage listening for a difference in the sound. and that's when they fail catastrophicaly, when the damage goes unseen and the tube loses it's structural integrity. then POP!

? bicycle frames are not made out of 1 3/4" .098 wall tubing either. so it is relative, just at a different scale. chromoly fails on a regular basis in mountain bike frames, and i know there are plenty of chassis and cages made out of that.
 
Guess you can just hold your cage up then.

If you really want to save weight, build your cage out of Sch. 40 pvc, its pretty strong stuff
 
I've got this pretty tough material you guys should look into, it hasn't been used in automotive fabrication yet but I bet it's definitely going to catch on- this stuff is TOUGH. So I haven't seen it before but it's definitely metal. I've thrown this stuff at the floor, stomped on it, kicked it, even put it on my desk and elbowed it, DIDN'T EVEN BEND. So I figured, ya no one's going to take those tests seriously so I took it to the EXTREME. I got a ladder and brought it to the top of a 2.5 story building and just wooped straight down at the cement. When I went to go check it out, much to my amazement NOT A SCRATCH ON IT. I thought to myself, can I take this even further!? So here's what I did, I got in my car, hopped on the highway and got up to 75mph and as I drove by a building I chucked it out my window into a wall. Guess what, still looked BRAND NEW. Try that with HREW, DOM, Chromoly, Stainless steel, I guarantee it would bend. I've got NASA on the line and they're going to stop by tomorrow to come check this stuff out. I'm definitely gonna patent it, but I'll let you guys in on the first batch for sure. Easily your best choice for cage material.
