There is also lots online about the thickness and the number of layers used on boat hulls. By the looks of things lots of companies use double layers of 6mm and use the outer as a of type sacrifical skin. Very similar to how galvanising was used in the olden days for sacrifical protection. Been a while since I did my materials module on my degree so maybe resins have changed and the pre-treatment process has changed for the better.
Hello Chaps, I can help a little the technical aspects.
Mr Dimmadan, Sorry but you are almost there. I recommend a refresher from your course notes. 😀
Carbon fibre is on its own is not woven. But it can be, its not always used in a woven form. Getting it wet is nothing like getting water on cardboard and your bars will never bend rather than snap. Carbon fibres do not soak up water. Carbon composites are stiff, but also brittle. In the marine industry you do sometimes see outerskins of different materials, but this is not anything to do with galvanising (galvanising prevents corrosion on a surface, I think you meant galvanic corrosion and the use of a sacrificial anode) This is not related to our problem here.
So to the question: I guess it is whether the bars are still ok and usable?
My first question is how hard did you hit them ? I can see that you have a scratch, but did they experience some real impact ? If they did it is likely that you have caused some internal damage to the bars which will help them to fail later. You are unlikely to know this without the use of some non-destructive testing equipment (ultrasound is good!) If you don’t happen to have this at your disposal you could strip the bars off your bike and use something to tap the surface. Tap the around the good end and then the area of suspected damage, if there is a change in tone its likely that damage is significant. Although this still does not guarantee that your bars are fine. If you are doing very aggressive and demanding riding it could be a problem and the bars have some internal damage. They could just snap and probably leave a very jagged and sharp surface which might be a danger in itself.
The real worry might be that you have started a crack with your scratches any crack will propagate and cause the bars to fail. In short, if they have really had an impact I would probably not use them again. Although its hard to tell without seeing and touching them. If you want some more info and have more detail, drop me an email and we could discuss further if they are good or if you might want to repair them.
Cheers
