Differences in Carbon Fibre

Bas Jaski didn't say a CF/resin matrix doesn't undergo elastic deformation. He said, in effect, that it doesn't experience plastic deformation like aluminum. For example, if your friend made bows out of aluminum like that used in Ferrari bodies, bending the tips together would result in a bow which would be permanently bent and unusable. That's because it was taken past the range of elastic deformation into plastic deformation.

CF parts typically experience elastic deformation too, like the bow you mention; i.e. the part can "spring back". But once the elastic limit is exceeded, the part is likely to fracture rather than bend. Try bending that bow into a tighter and tighter circle. At some point it will break. That's what Bas Jaski was trying to say, I think.

Yes you are correct .

In F1 it also ''bends'' so to say.

Indeed what I was getting at, answering the question to another, who seemed afraid what would happen if lets say an interior part or bumper got hit somehow, in that sense it would break .
