Carbon frame scratches

Errrr .... I had to look a couple of times to even find what you were talking about. I can't see the rest of the bike, but neither of the scratches shown in the photos are signs of impending structural doom. You should stop worrying and go for a ride.

I think Jack Osbourne snr above makes a good point. Give your fork and steerer a good look over since you've had a crash. You don't want those bits to give way at any sort of speed due to some damage you may have overlooked.

The damage on the chainstay looks superficial. It doesn't look like it's damaged the carbon fibres. I would get in touch with Planet X if you want to touch it up. They should know what matrix material (ie. plastic or resin) they've used in construction and hence what is safe to use on it.

The dropout looks like it's just got regular wear and tear and shouldn't be anything to worry about.

None of that looks anything more than superficial to me. Certainly my frame has much worse scratches on the chainstay and that has been cleared by a carbon frame maker for use. Certainly the drop out doesn't look  bad at all. 

Emailing PX makes sense.

In my humble opinion the scratches are superficial and absolutely not going to cause any issues. Seal them up to stop any further deterioration and you'll be good to go.

HOWEVER... as with any crash damaged frame, I would be examining every square millimeter of it for any signs of damage ie cracks, cracks in lacquer, whitening in lacquer etc.

I would also take the fork out and examine both the blades and the steerer. Don't just assume it's okay.

I suspect you'll be fine though.

Isn't the dropout metal?

if there is no fiber, don't wory , if you can see fiber like torn cloth, throw it away. you can cover it with some epoxy glue to seal it.  for the grooves on the dropouts from the axle, dont worry with that too, everybody has that when there is a threaded axle present.

Agree, doesn't sound like serious damage (pitch is used by carbon fibre repairers but using pretty sophisticated kit). Buy a bottle of cheap clear nail varnish and paint it over the scratch to seal it.

This is one of those funny ones. Anyone on here can say anything and there is no comeback, little evidence of their expertise or anything, Your LBS won't beinterested because of liability. That said.....

I have a cannondale evo 6 hi-mod. The chain came off the chainrings and scored the frame deeply. I took it to Graeme Pearson who is a world reknowned carbon frame builder, and very very good repairer and he ok'd it. I can't see any fibres, there's deep (.5mm deep?? scoring through the clear coat and in to the epoxy. 

My local LBS also manufactures bikes, and they have manufactured a few carbon bikes. They've (as yet) not had a single carbon frame from any manufacturer fail catastrophically (as in failed in such a way that it put the rider in unexpected peril) post crash. Carbon frames tend to either break completely immediately, or fail gradually over a period of time. They have had broken seat stays, chain stays, down tubes, seat tubes, bottom brackets, head tubes cross tubes that have all cracked through or around and the bike has still been rideable, much as you would expect with an aluminium or steel bike. 

I can't view your pictures but my personal opinion is that the drop outs are fine, and probably the inside of the chainstay. If you want something to compare it to, look under your fork crown where stones chip and score the carbon fibre. You'll like as not find it quite messy in there and be able to compare those to your chainstay scrape. Either way, even if your chainstay does fail completely, it is very unlikely to deposit you unceremoniously and unexpectedly on the road.
