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 dangerous assumptions here.
The resin used is fairly important in any composite, and there's a huge difference between air-dry, room-temp curing epoxies and the exotic stuff the aerospace and F1 people use in their autoclaves. Any figures you read in a book on relative strengths are theoretical, and stuff you can get off the shelf isn't necessarily up to top standards, unless that shelf happens to belong to Boeing, et al. Strong in pure tensile strength does not mean strong in all dimensions under all uses. It's hard to align CF fibers so all of the forces are taken only in tension along the length of the fiber, and CF is actually quite weak under bending loads. |
