Don't try this at home. I am taking personal responsibility for what happens in my car.
Hi all, I recently purchased a fire extinguisher for my car (it weighs 1.5 lbs or 0.68 kg). I browsed the internet for a decent bracket to mount it inside my car, under the front passenger seat. Everything was fairly expensive which made me want to make a DIY version that would be cheaper.
I have been trying to find what sort of materials I can/should use. The last thing I want is the bracket to break and have a 1.5 lbs metallic projectile flying inside the car in the event of a crash.
The bracket should be 16" or ~40 cm wide so that I can use the bolts on which the passenger seat is mounted to attach the bracket. (See picture below)
Obviously I could use some thick steel and be safe but I don't really have easy access to tools to cut metals so I would like to try something else.
My requirement for the bracket is that it should be able to hold on to the fire extinguisher in the event of a frontal collision on the freeway. Which would be an impact of, if my memory serves me right, of
65 mph + 65 mph = 130 mph or ~210 kmhIf my math is correct this would be equal to
210000 * 0.68 = 3966 N
After that I'm not sure where to go... If I was considering using a PVC pipe, would I be able to relate those Newtons to the tensile strength of the pipe to figure out if it would hold up?
I had also thought about 3D printing the bracket but a friend pointed out that it's hard to make measurements with PLA because the printer layers the material so the "resistance" or "strength" is different in different directions.
I am also open to other material suggestions! Thank you.
