Possible stringer De-lamination

Hey guys I need some advice. I have a 2002 Supra launch. As I was cleaning out the engine bay this year I found what looks like some stringer De-lamination. Problem is I’ve looked around the Internet and I can’t even find pictures of what the Composite stringers look like. I don’t think they’re the old-school Supra 2 x 12’s. From the pictures I’ve seen it’s sort of a whole Lay in subfloor. I’m not sure if what I’m seeing is something to be concerned about. I’ll include a brief video hopefully you’ll be able to make out the loose fiberglass I am talking about.Attachment 19375Attachment 19376

It’s hard to see but that whole lip is not attached to the plastic sidewall anymore
