I was idly watching a youtube video of someone making a one piece front and they made a point of adding layers of kevlar to the inner wing to protect the fibreglass outer surface from becoming star-crazed from stones flinging up off the tyres.
This got me thinking. After I've finished de-rusting & welding up holes in the rear inner wheel arches, why not add several layers of kevlar & epoxy directly onto the steel inner arch? (Or onto the roughened protective paint)?
Instinctively I imagine there must be a problem - either the kevlar wearing through quickly or water somehow getting behind and delaminating plus creating a rust trap. On the other hand it must take more of a beating than any paint and won't come off as easily as rubberised coatings like truck bed liner.
Has anyone experience of doing this? Not experience of laying up per se but experience of doing it and finding it did or didn't work?
Similarly as it's just popped into my head. As a '60s car with no side impact protection, would kevlaring the inside of the outer door skins make any difference? I've seen something where a standard door is replaced with a carbon fibre one but with kevlar and foam to lose weight but still have some impact strength for racing regs. In this case as a race car there's no window mechanism or other gubbings inside the door so the new door is solid with foam. Would Kevlar or kevlar with something like nomex add worthwhile crash protection or just be ineffective?
It's here:
Thanks
