So,
Carbon fiber is 6 times stronger than steel. here are my thoughts. take off the outer rocker. Fix the rust with new steel. sandblast the area Lay on a layer of CF directly to the inner long front to back, wrap in to the bottom and top horizontal layers. when using CF and bonding it to steel, I have read that you would use an epoxy resin to bond it directly to the steel, so it would be the same as putting por 15 on steel (por 15 is an epoxy layer) So, thoughts? plus, minus?

lots of good thoughts... I will tell you what I know... Carbon fiber has been tested in a specific application...to reinforce aging bridges..it is applied cold to bare sand blasted steel to add structural integrity to these aging structures... The epoxy is very specific, and por 15 is not it. I would use the correct epoxy, it is available. So, in the bridge application, it is applied in the field, in varying weather conditions, and has held up to being exposed to many different twisting and bending stresses. I would use the same cloth and epoxy that is being used for the bridge application. I still have my concerns...but I am gonna run this by a few composite engineers to get some real world feedback, I may even track down the company that is doing the bridge tests to get some feedback... I was just thinking that it would be a great way to stiffen up the car with less weight. And, if it does not work...I can always remove it and add more steel. Rich |
