Binding two carbon fiber ends

[holmesss]

Hello,
The question might be a bit more in the materials field .
Is there a way to join two ends of carbon fiber?
I know that you can bond them together, but if we do that, will the properties of the joint be the same as the other locations of the 2 pieces or will it be weaker?
Whats the best way to have the best junction if for example i want to link two ends of a normal carbon fiber sheet and then have the least deformation possible when I subject it to tension(for example have the normal deformation that I would have when I put a continuous sheet of FC to tension)
Thank you

Your question is like asking how to join two ends of wood. I don't know why anyone would be interested in answering such a vague question.

Maybe it would be interesting to answer because it's called "helping"..
If I knew something on the subject I wouldn't have bothered you.
So yes maybe it's easy for you, may you share your opinion?
Thank you.

you can make a bonded or fastened joint, either by overlapping the sheets, or by adding overlapping separate doubler sheet. Either way, it is very difficult to obtain tensile strength of the joint that is equal to the basic sheet.

What specific material, thickness, configuration are you attempting to join? What is the application? A lot more detail is needed to be able to provide specific recommendations.

Thank you SWComposites.
It was a curious question because I read somewhere that lasers could join FC sheets and I wanted to make sure if that is possible.
As I understood from your answer, there is no way to chemically join the two structures as if they were continuos again, which makes sense.

No, cannot join the fibers directly. Can use lasers to heat up fiber reinforced thermoplastic sheets and "weld" the resin together, but there is still a discontinuity in the fibers.

Perfect thank you very much!
