I see no evidence of high friction movement by the skewer.
That fork looks like it dropped out of the frame & landed on the dropout resulting in damage.
I don't like the look of how the metal was inset into the epoxy. Looks a rush job.
There should be an excess of epoxy.
The excess epoxy should be faired for a nice smooth transition effectively encapsulating the part.
It is clear that the part that chipped away was unsupported & not bonded to anything. (Void)
Of the part that did have epoxy, there was no bond to the metal.
This indicates proper manufacturing cleanliness standard was not obtained.
A quality drop out is more than a thin metal washer placed by bare hands with the tiniest possible squirt of epoxy.
Bargain internet brand?
Safe is not a word I would associate with this fork.
