JUST A THOUGHT FOR STRENGTH IN FRAMES

[powerzap69]

I Was Just Admiring The Good Work Performed By Skidsteer On His Buggy. *and A Thought Occurred To Me. *it May Be Way Out Of Bounds And Unfeesable But May Be An Idea To Consider. *lets Start With A Simple Excample. *take A Soda Pop In A Can. *not Very Easy To Puncture The Can With A Blunt Object. *now You Empty The Can And Its Easy *to Rupture Or Break The Outer Surface. *now I Know Everyone Is Looking For Lightweight Aplications. *so Instead Of A Liquid What About Say An Inexpensive Harmless Un Flamable Gas Like Nitrogen. *itas Inert And Would Actually Help Sustain A Fire In The Case Of An Accident. *by Forcing Out All Of The Oxygen. *commonly Used In Pressure Testing Pipes After Welding. *like I Said I May Be Way Off Base With This Idea, I Know Most Failures Occur At The Componants And Rarely The Frame. *but May Be An Idea To Explore Even In The Componants. *just A Thought Looking For Reason

Only bad part is you got a hole in every section to weeken the structure....And caps are for when you are pissed off. *

[powerzap69]

I THOUGHT CAPS WERE FOR YELLING, I'M NOT ALWAYS MAD WHEN I'M YELLING. but i will tone it down for those that are more sensitive.. *and he hole wouldn't have to be especially large. *look at the structural gains a soda can has. *wouldn't it be worth the effort? *its hard coming up with new ideas in this day and age. *heck now there taking engine parts and dipping them in criogenics to ease tension points in molecular structure for race engines.

Sorry but I see no benefit that can be gained.The soda can is very thin wall and easily deformed and as such it takes only a bit of pressure inside to "stiffen " the walls significantly.The steel used in a frame I doubt would see the same results since the walls are very stiff to start with.Extremely high pressure maybe but the pressures needed would IMO be dangerous in and of themselves..

What if they were injected with expanding foam?Also light wieght and you would float if you ended up in the drink.

[masterfabr]

Aw,c'mon ,the guy was floating an idea past us.

[Rorty]

If the tube wall was as thin as what you're suggesting, then even a small crack would let the internal pressure drop and all of a sudden you would be driving a buggy with similar properties to a garden hose.

Filling the tube with a rigid foam has merit and the principal is already used in sandwich laminate construction. The choice of foam would be the challenge; it would have to be easy flowing (to fill all cavities) and yet rigid enough to withstand the sorts of impacts and deformations likely in buggy driving/racing.

A possible solution would be to pre-fill the tubes with a fire resistant foam that could withstand the heat of welding the tubes together. Nice idea, but the costs would probably outweigh the benefits of time tested tubular steel construction.

See guys! It could work [smilie=icon_razz2.gif]

negative feedback is as welcome as posative feedback as long its done like rorty did. *he explained why and a great explenation at that. *but without proper testing of the thery, you cant really make a determination of the benafits. *its already been tested more then likely but has it been tested with all the new materials we have on hand. *thanks rorty. *i value your inpute as well as other ideas. *i have an invention that i've done an online patten for which could be a great benafit to those on this site being there are probably alot of welders here. *i just dont know how to properly introduce it into the mainstream as of yet. *keep them coming. *this is simalar to how everday things we use were thought up.

[powerzap69]

and by the way, i wasn't suggesting on using a thin tube. *but merely to reinforce the metal you already choose to use. *no harm in making things stronger.
